Code Array

Find the frequency of a element in array

Here given code implementation process.

// C Program 
// Find the frequency of a element in array
#include <stdio.h>

//Display elements of given array
void printArray(int arr[], int size)
{
	for (int i = 0; i < size; ++i)
	{
		printf("  %d", arr[i]);
	}
}
// Finding the frequency of a element (number) in an array
void findFrequency(int arr[], int size, int element)
{
	// Define resultant variable
	int counter = 0;
	// Execute loop through by size
	for (int i = 0; i < size; ++i)
	{
		if (arr[i] == element)
		{
			// When get element 
			counter++;
		}
	}
	// Display calculated result
	printf("\n Element %d frequency is : %d", element, counter);
}
int main(int argc, char const *argv[])
{
	// Define array of integer elements
	int arr[] = 
    {
		3 , 6 , 1 , 2 , 4 , 7 , 2 , 3 , 4 , 2 , 3 , 2 , 3 , 1 , 1 , 1 , 1
	};
	// Get the size
	int size = sizeof(arr) / sizeof(arr[0]);
	printf(" Array elements \n");
	printArray(arr, size);
	findFrequency(arr, size, 1);
	findFrequency(arr, size, 2);
	findFrequency(arr, size, 6);
	findFrequency(arr, size, 9);
	return 0;
}

Output
