C Program to Remove First Occurrence of a Character in a String

In this tutorial, we will learn to create a C program that will Remove the First Occurrence of a Character in a String in C programming

Prerequisites

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

Operators in C Programming.
Basic Input and Output function in C Programming.
Basic C programming.
For loop in C programming.
Conditional Statements in C programming.

What is a string?

As we all know the String is a collection of characters and words. The word is a collection of alphabets. For string, only one variable is declared which can store multiple values. The String can consist of all the typeable data it means Digits, Alphabets, Symbols, etc.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input string from the user.

3. Finding the characters in string.

4. Passing those variables to for loop.

5. Using conditional statements for the program to removing the first occerence character.

6. Printing the result string.

7. End the program.

Removing the First Occurrence of a Character in a String

In this program first, we will take input string from the user. Then we will take the character to be removed from the user. Then will be Removing the First Occurrence of the Character in that String. Printing the result string.

Let us take the example program from the below code for Removing the First Occurrence of the Character in that String.

Program Code:-

/* C Program to Remove First Occurrence of a Character in a String */
 
#include <stdio.h>
#include <string.h>
 
int main()
{
    //declaring the required vaiable for the prorgam.
  	char strg[100], chr;
  	int i, len;
  	i = 0;
    //Taking input string from the user.
  	printf("\n Please Enter any String :  ");
  	gets(strg);
  	//Taking the character to  be removed.
  	printf("\n Please Enter the Character that you want to Remove :  ");
  	scanf("%c", &chr);
  	
	len = strlen(strg);
	//Removing that first occurence character.
  	while(i < len && strg[i] != chr)
	{
		i++;
	}  
  	
  	while(i < len)
  	{
  		strg[i] = strg[i + 1];
		i++;  
	}
	//printing the string after removing the character.
	printf("\n The Final String after Removing First occurrence of '%c' = %s ", chr, strg);
	
  	return 0;
}

/* C Program to Remove First Occurrence of a Character in a String */

#include <stdio.h>

#include <string.h>

int main()

{

//declaring the required vaiable for the prorgam.

char strg[100], chr;

int i, len;

i = 0;

//Taking input string from the user.

printf("\n Please Enter any String : ");

gets(strg);

//Taking the character to be removed.

printf("\n Please Enter the Character that you want to Remove : ");

scanf("%c", &chr);

len = strlen(strg);

//Removing that first occurence character.

while(i < len && strg[i] != chr)

{

i++;

}

while(i < len)

{

strg[i] = strg[i + 1];

i++;

}

//printing the string after removing the character.

printf("\n The Final String after Removing First occurrence of '%c' = %s ", chr, strg);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

strg[100] = it will hold the string value.
chr = it will hold the string value.
len = it will hold the integer value.

1. Initiating the program

2. Using size of function to print the size of character data type.

3. Using size of function to print the size of integer data type.

4. Using size of function to print the size of float data type..

5. Using size of function to print the size of double data type.

6. End program.

6. End program.

Program to check the size of predefined data types in C programming.

In every programming language, there are many predefined datatypes available. Today we will create a program that will print the size of integer, character, float, and double in bytes. Because every datatype variable reserves the size in memory for each type of variable.

With the help of this program, we can find the size of the above data types.

Program Code:-

#include<stdio.h>
int main() 
{
    //declaring the requireed variable for the program.
    int intType;
    float floatType;
    double doubleType;
    char charType;
    
    // sizeof for printing the size of data type integer
    printf("Size of int: %zu bytes\n", sizeof(intType));
    // sizeof for printing the size of data type float
    printf("Size of float: %zu bytes\n", sizeof(floatType));
    // sizeof for printing the size of data type double
    printf("Size of double: %zu bytes\n", sizeof(doubleType));
    // sizeof for printing the size of data type character
    printf("Size of char: %zu byte\n", sizeof(charType));
    
    return 0;
}

#include<stdio.h>

int main()

{

//declaring the requireed variable for the program.

int intType;

float floatType;

double doubleType;

char charType;

// sizeof for printing the size of data type integer

printf("Size of int: %zu bytes\n", sizeof(intType));

// sizeof for printing the size of data type float

printf("Size of float: %zu bytes\n", sizeof(floatType));

// sizeof for printing the size of data type double

printf("Size of double: %zu bytes\n", sizeof(doubleType));

// sizeof for printing the size of data type character

printf("Size of char: %zu byte\n", sizeof(charType));

return 0;

}

Output:-

Printing the size of character data type using the size of function.

Integer type printing its size by using sizeof function.

Printing the size of float data type using the size of function.

Printing the size of double data type using the size of function.

In the string “Hello”, there are five characters, they are as follows

Here,

‘H’ is a character in the Upper case.

‘e’ is a character in the lower case.

‘l’ is a character in the lowercase.

‘l’ is a character in the lower case.

‘o’ is a character in the lowercase.

What is a percentage of numbers?

The percentage of all the marks is calculated by adding the total marks. And then we will divide it by the maximum marks and multiplied by 100.

What is the average of numbers?

The average of numbers in mathematics means that all the numbers are added and then the sum of all the numbers is divided by the total number of objects.

It means if there are 5 subject marks as follows {60,60,60,80,70} then the average will be:-

average = 60+60+60+80+70/5

average = 60.

Algorithm:-

2. Taking the input marks from the user.

3. Adding those marks finding the total.

4. Finding the average from the total marks.

5. Finding the percentage of those marks.

5. Printing the result numbers.

Program to calculate total, Average, and Percentage of Five Subjects.

In this program, we will first take the marks of all five subjects from the user. And then we will add them to find the total marks. Now the total will be divided by the number of subjects to find the average. Then the total will be divide by maximum marks and multiply by 100. Last, we will print the outputs.

Example using the below program.

Program Code:-

/**
 * C program to calculate total, average and percentage of five subjects
 */

#include <stdio.h>

int main()
{
    /* declaring the required variables for the program. */
    float eng, phy, chem, math, comp; 
    float total, average, percentage;

    /* Taking the Input marks of all five subjects. */
    printf("Enter marks of five subjects: \n");
    scanf("%f%f%f%f%f", &eng, &phy, &chem, &math, &comp);

    /* Calculate total, average and percentage of the marks. */
    total = eng + phy + chem + math + comp;
    average = total / 5.0;
    percentage = (total / 500.0) * 100;

    /* Print all the results total marks average of 
    numbers and the percentage */
    printf("Total marks = %.2f\n", total);
    printf("Average marks = %.2f\n", average);
    printf("Percentage = %.2f", percentage);

    return 0;
}

/**

* C program to calculate total, average and percentage of five subjects

#include <stdio.h>

int main()

{

/* declaring the required variables for the program. */

float eng, phy, chem, math, comp;

float total, average, percentage;

/* Taking the Input marks of all five subjects. */

printf("Enter marks of five subjects: \n");

scanf("%f%f%f%f%f", &eng, &phy, &chem, &math, &comp);

/* Calculate total, average and percentage of the marks. */

total = eng + phy + chem + math + comp;

average = total / 5.0;

percentage = (total / 500.0) * 100;

/* Print all the results total marks average of

numbers and the percentage */

printf("Total marks = %.2f\n", total);

printf("Average marks = %.2f\n", average);

printf("Percentage = %.2f", percentage);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

eng = it will hold the float value.
chem = it will hold the float value.
phy = it will hold the float value.
math = it will hold the float value.
comp = it will hold the float value.
total = it will hold the float value.
