C example to Count the frequency of each Element in an Array

In this tutorial, we will learn to create a C program that will Count the Frequency of each Element in an Array using C programming.

Prerequisites

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

Program to Count Frequency of each Element in an Array.

In this program, we will count the frequency of each element in the array. The frequency means the occurrence of the element in that array.

In this tutorial, we will first initialize the array. After that, we will find the length of the array. Then we will count the frequency of every element in the array. At last, we will print the frequency of each element to the user.

With the help of this program, we can Count the Frequency of each Element in an Array.

Program Code:-

/* C Program to Count Frequency of each Element in an Array */
#include <stdio.h>  
   
int main()  
{  
    //Declaring the required variables for the program
    int arr[] = {1, 2, 8, 3, 2, 2, 2, 5, 1};
    //arr[] = it will hold the array elements.
    //i = it will hold the integer value for the controlling of loop.   
    //j = it will hold the integer value for the controlling of child loop.      
    //Calculate length of array arr  
    int length = sizeof(arr)/sizeof(arr[0]);  
      
    //Array fr will store frequencies of element  
    int fr[length];  
    int visited = -1;  
      
    for(int i = 0; i < length; i++){  
        int count = 1;

    }  
      
    //Displays the frequency of each element present in array  
    printf("---------------------\n");  
    printf(" Element | Frequency\n");  
    printf("---------------------\n");  
    for(int i = 0; i < length; i++){

C Program to Find Largest and Smallest Number in an Array

In this tutorial, we will learn to create a C program that will Find the Largest and Smallest Number in an Array using C programming.

Prerequisites

Before starting with this tutorial, we assume that you are the 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.
Arithmetic operations in C Programming.
Conditional Statements in the C Programming.

Find the Largest and the Smallest Number in an Array.

In this program, First, we will first take the size of the array from the user. Then we will take the elements of the array from the user. After that, we will compare every element of the array and Find the largest and the Smallest Number in that Array. Then we will print the largest element and the smallest element of the array to the user.

With the help of this program, we can be Find the Smallest Number in an Array.

Program Code:-

// C program to find the smallest and largest element in an array

#include<stdio.h>

int main()
{
//declaring the required variables for the prorgam  
int a[50],i,n,lrg,sml;
//i = it will hold the integer value for the loop
//n = it will hold the integer value for the input size of array
//lrg = it will hold the integer value for the largest value of the array
//sml = it will hold the integer value for the smallest value of the array
//a[50] = it will hold the integer value for the elements of array

//Taking the input size of the array from the user.
printf("\nEnter the number of elements : ");
scanf("%d",&n);
//Taking the input elements of the array.
printf("\nInput the array elements : ");
for(i=0;i<n;++i)
scanf("%d",&a[i]);
//Finding the largest and the smallest number 
lrg=sml=a[0];

for(i=1;i<n;++i)
{
if(a[i]>lrg)
lrg=a[i];

if(a[i]<sml)
sml=a[i];
}
//Printing The smallest element
printf("\nThe smallest element is %d\n",sml);
//Printing The largest element
printf("\nThe largest element is %d\n",lrg);

return 0;
}

// C program to find the smallest and largest element in an array

#include<stdio.h>

int main()

{

//declaring the required variables for the prorgam

int a[50],i,n,lrg,sml;

//i = it will hold the integer value for the loop

//n = it will hold the integer value for the input size of array

//lrg = it will hold the integer value for the largest value of the array

//sml = it will hold the integer value for the smallest value of the array

//a[50] = it will hold the integer value for the elements of array

//Taking the input size of the array from the user.

printf("\nEnter the number of elements : ");

scanf("%d",&n);

//Taking the input elements of the array.

printf("\nInput the array elements : ");

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

scanf("%d",&a[i]);

//Finding the largest and the smallest number

lrg=sml=a[0];

for(i=1;i<n;++i)

{

if(a[i]>lrg)

lrg=a[i];

if(a[i]<sml)

sml=a[i];

}

//Printing The smallest element

printf("\nThe smallest element is %d\n",sml);

//Printing The largest element

printf("\nThe largest element is %d\n",lrg);

return 0;

}

Output:-

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

n = it will hold the integer value.
i = it will hold the integer value.
a[50] = it will hold the integer value.
sml = it will hold the integer value.
lrg = it will hold the integer value.
