C Program to Check Leap Year

In this tutorial, you will learn to create a c program to find given year is a leap year or not.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

C Operators
Conditional statement.
Basic input output .

Example:

So logic behind to check whether a year is leap or not is:
Logic of Leap Year:
If the given value is completely divisible by 4, 100 and 400 then it is a leap year.
If the given value is divisible by 4 but not by 100 then it is a leap year.

Logic for not a Leap Year:
If the given value is not divisible by 4 then it is not a leap year
If the given value is divisible by 4 and 100 but not divisible by 400 then it is not a leap year.

For example,

1221 is not a leap year.
2000 is a leap year.
1890 is not a leap year.

Program to Check given year is a Leap Year or not.

Here fist we take a year from user and with help of logical operator(&& and ,|| or) we will check multiple condition in a single if statement and get the required result.

#include <stdio.h>

int main() {
   int year;
   printf("enter any year \n:");
   scanf("%d",&year); //taking value from user..
   if (year % 4 == 0 && year % 100!= 0 || year%400 == 0) //logic
   {
      printf("%d is a leap year", year);
   }
   else
   {
      printf("%d is not a leap year", year);
   }

   return(0);
}

#include <stdio.h>

int main() {

int year;

printf("enter any year \n:");

scanf("%d",&year); //taking value from user..

if (year % 4 == 0 && year % 100!= 0 || year%400 == 0) //logic

{

printf("%d is a leap year", year);

}

else

{

printf("%d is not a leap year", year);

}

return(0);

}

Output

C Program to Check Leap Year

In our program, we have first declared and initialized a set variables required in the program.

year =taking year value from user.

First of all take a value from user to check whether a year is leap or not is,
then we check if the given value is completely divisible by 4, 100 and 400 then it is a leap year.
If the given value is divisible by 4 but not by 100 then it is a leap year.

C Program to Generate Random Numbers

Leave a reply

In this tutorial, we will learn to create a C program that will generate a random number using C programming.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Basic C programming.
Operators.
Looping statements
For Loop.
Basic input/output.
Inbuilt library function.

What Is Random number?

Random number is are set of digits (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) arranged in irregular order.

As you can see here some random number between 1 to 10 are shown in above image we will use here a rand() function to generate 10 different random number in our our program let us see how to do that.

C Program to Generate Random Numbers.

Here in our program we are going to use rand() inbuilt function which is define in header file stdlib.h with the help of this function we genrate 10 differnet random number let have a look at program.

#include <stdio.h>
#include <stdlib.h>

int main()
{
int i,no; // declaring variable
        printf("Random Number are\n");
	for (i = 0; i < 10; i++) 
        {
		no = (rand() % 10); // Random function
		printf("%d\t", no); // printing random numbers
	}
	return 0;
}

#include <stdio.h>

#include <stdlib.h>

int main()

{

int i,no; // declaring variable

printf("Random Number are\n");

for (i = 0; i < 10; i++)

{

no = (rand() % 10); // Random function

printf("%d\t", no); // printing random numbers

}

return 0;

}

Output

C Program to Generate Random Numbers

In the above program, we have first declared and initialized a set variables required in the program.

no = For holding random values
i = for iteration.

First of all we declare two variable i for iteration and no for holding value provided by rand() function. Here in this program we use rand() function to generate 10 random number in our program.In our program we use for loop to print Ten different random value using rand() function at multiple times.

As we can see in above image that in each iteration the rand() function called every time gives us a new random number between 1-10 because we use range from 1-10 to print 10 different values if we want to print ten different values form 1-100 then with rand() function we have to use rand()%100 it will gives us ten different value between 1-100.

What Is Simple interest?

Simple interest is basically a calculation of the interest charged on a given principal amount with in a particular part of time by the bank to customer or taken by bank.

Simple Interest = (p * n * r) / 100

here, p = Principal,

n = Time Period or year.

r = Rate of Interest.

Example

Let take an example of this,

p=5000,r=10,and t=1 year.

then,

Output

Algorithm

Firstly define Principal, rate and Time of loans.
Apply the formula.
Output Simple Interest.

C Program to Calculate Simple Interest.

First of all we take principal ,rate and time and pass them to function as a argument that will calculate the simple interest.let see a program for these.

#include<stdio.h>
float Simple_int(float p, float r, float t) // function for finding simple interest
{
    float si;   
    si = (p * r * t)/100; // formula
    return si; // returning yhe value of si
}
 int main()
{
    float a,b,c;
    float intrest;
    printf("\nEnter Prinicpal :\t");
    scanf("%f",&a);
    printf("\nEnter year:\t");
    scanf("%f",&b);
    printf("\nEnter Rate:\t");
    scanf("%f",&c); // taking all 3 values p,r and time
    intrest = Simple_int(a,b,c); // passing value in function
    printf("\nSimple Interest = %.2f\n", intrest); //output
    printf("\n");
    return 0;
}

#include<stdio.h>

float Simple_int(float p, float r, float t) // function for finding simple interest

{

float si;

si = (p * r * t)/100; // formula

return si; // returning yhe value of si

}

int main()

{

float a,b,c;

float intrest;

printf("\nEnter Prinicpal :\t");

scanf("%f",&a);

printf("\nEnter year:\t");

scanf("%f",&b);

printf("\nEnter Rate:\t");

scanf("%f",&c); // taking all 3 values p,r and time

intrest = Simple_int(a,b,c); // passing value in function

printf("\nSimple Interest = %.2f\n", intrest); //output

printf("\n");

return 0;

}

Output

In the above program, we have first declared and initialized a set variables required in the program.

a = for taking value of Principal.
b = for taking value of rate.
c= for taking value of time.
p= for holding value of a.
r = for holding value of b.
t= for holding value of c.
si= calculate simple interest.

This program takes three values of principal,rate and time in a,b,c from user and then passing these value in function Simple_int(a,b,c) as argument the above function after calculating value function returns simple interest.

As shown in above figure. The value return by the function is hold by result variable and with help of result we can print the simple interest using function.

C Program to Find Factor of a Given Number

Leave a reply

In this tutorial, we will learn to create a C program that will find Factors of a number using C programming.

Prerequisites.

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators.
If else statement.
C for Loop.
Basic input/output.

What Is Factor of number is?

Factors:=> So factors of a number are numbers that divide the number completely and remainder of divisor is equal to zero.

Example:->

The number 6 has four factors: 1, 2, 3, and 6 because all this number divide the number six completely.

C Program to Find Factor of a Given Number.

In this program we will find factor of given number using if else statement and for loop. We would first declared and initialized the required variables. Next, we would prompt user to input the number . Later we will find factors.

#include <stdio.h>
int main() {
    int no, j; //declaring variables 
    printf("Enter any  positive integer : "); // taking a postive number
    scanf("%d", &no);
    printf("Factors of gievn number  %d are: ", no);
    for (j = 1; j <= no; ++j)  // iteration of loop till given number
   {
        if (no % j == 0) // finding factors
       {
            printf("%d ", j); // printing factors.
        }
    }
    return 0;
}

#include <stdio.h>

int main() {

int no, j; //declaring variables

printf("Enter any positive integer : "); // taking a postive number

scanf("%d", &no);

printf("Factors of gievn number %d are: ", no);

for (j = 1; j <= no; ++j) // iteration of loop till given number

{

if (no % j == 0) // finding factors

{

printf("%d ", j); // printing factors.

}

return 0;

}

Output

C Program to Find Factor of a Given Number

In this program we will take a positive integer from user by prompting and with the help of loop and if else statement we will displays all the positive factors of that number.

In the above program, we have first declared and initialized a set variables required in the program.

no = It will hols number given by user.
j= for iteration of loop and finding factor.

So the logic behind computing factors of a number is we will run a loop from 1 to no, increment 1 in each iteration.
The loop structure should look like this

Within the loop in each iteration we check the condition that j is a factor of no or not. To check factor we use divisibility of number by using modulo division

i.e. if( no % j == 0) then j is a factor of no If j is a factor of no then we will print the value of j.So we will get the required factors of given number.

C Program to Check Lower Upper Case

In this tutorial, will learn to find entered character is an Uppercase or in a lower case using C programming language.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Basic Programming
Operators.
looping statements
For Loop
If else statement.
Basic input/output.

What Is Upper and lower case.

Uppercase letters are capital letters. they usually signal reader that something is important or significant in a Text.Uppercase letters represent the beginning of a sentence or a proper noun.
uppercase letters: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.

lowercase letters In writing, most letters are lowercase. Lowercase letters are all letters that do not begin a sentence or refer to a proper noun.Each word in this sentence other than the first word is written in lowercase.
lowercase letters: a b c d e f g h i j k l m n o p q r s t u v w x y z.

C Program to Check Lower Upper Case

#include <stdio.h>
int main() 
{
    char ch; //declaring varibles
    printf("enter any character ");
    scanf("%c",&ch); //taking values    
   if (ch >= 'A' && ch <= 'Z') // checking upper case condition
    {
        printf(" is an UpperCase character\n");
    }
    else
    {
         if (ch >= 'a' && ch <= 'z')  // checking lowercase condition
         {
             printf("is an LowerCase character\n");
        }   
        else
        {
            printf(" is not an aplhabetic character\n"); // if given value in not a character
        }
    }
    return 0;
}

#include <stdio.h>

int main()

{

char ch; //declaring varibles

printf("enter any character ");

scanf("%c",&ch); //taking values

if (ch >= 'A' && ch <= 'Z') // checking upper case condition

{

printf(" is an UpperCase character\n");

}

else

{

if (ch >= 'a' && ch <= 'z') // checking lowercase condition

{

printf("is an LowerCase character\n");

}

else

{

printf(" is not an aplhabetic character\n"); // if given value in not a character

}

return 0;

}

Output

In this tutorial, we will learn to create a C program that Find BUZZ FIZZ using C programming.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators
Basic C programming.
Basic input/output.
Looping statements
For Loop
If else statement.

What Is Buzz Fizz?

The concept of Buzz and Fizz is if integers between 1 to N, print “Fizz” if an integer is divisible by 3, “Buzz” if an integer is divisible by 5, and “FizzBuzz” if an integer is divisible by both 3 and 5.

Example:

A program that prints the numbers from 1 to no(suppose 15) .If number is a multiple of ‘3’ print “Fizz” instead if multiples of ‘5’ print “Buzz” and if multiple of 3 and 5 both then print “Fizz Buzz”.
1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14,
Fizz Buzz.

Buzz Fizz Program in C.

In this program we will print find Buzz Fizz using for loop. We would first declared and initialized the required variables. Next, we would prompt user to input the number of terms. Later we will find Buzz Fizz series of specified number of terms.

#include <stdio.h>
int main()
{
    int i,no; // declaring variables.
    printf("enter number ");
    scanf("%d",&no); // taking value from user.
    for(i=1; i<=no; i++)  
    {
        if(((i%3)||(i%5))== 0) // checking condition for FizzBuzz
            printf("number= %d FizzBuzz\n", i);
        else if((i%3)==0)   // for Fizz only
            printf("number= %d Fizz\n", i);
        else if((i%5)==0) // for Buzz only.
            printf("number= %d Buzz\n", i);
        else
            printf("number= %d\n",i);
    }
    return 0;
}

#include <stdio.h>

int main()

{

int i,no; // declaring variables.

printf("enter number ");

scanf("%d",&no); // taking value from user.

for(i=1; i<=no; i++)

{

if(((i%3)||(i%5))== 0) // checking condition for FizzBuzz

printf("number= %d FizzBuzz\n", i);

else if((i%3)==0) // for Fizz only

printf("number= %d Fizz\n", i);

else if((i%5)==0) // for Buzz only.

printf("number= %d Buzz\n", i);

else

printf("number= %d\n",i);

}

return 0;

}

Output

Buzz Fizz Program in C

In the above program, we have first declared and initialized a set variables required in the program.

no = number of terms to be printed
i = for iteration of loop.

Here in this program we will print number from 1 to no.If number is multiple of 3, we print “Fizz” instead of the number. as you can see in image below.

And if number is multiple of 5, print “Buzz” instead of the number.

And in final case if numbers which are multiples of both 3 and 5, print “FizzBuzz” instead of the number.So in our program we take a number from user at run time,suppose user gives a number 15 then the series of fizz , buzz and fizzbuzz is look like this.
