# Program : Find the frequency of each element in an array.

## Solution :

#include <iostream> using namespace std; void findFrequency(int array[], int size) { const int MAX_SIZE = 100; int frequencies[MAX_SIZE] = {0}; int i; // Calculate the frequency of each element for (i = 0; i < size; i++) { frequencies[array[i]]++; } // Print the frequency of each element cout << "Element\tFrequency" << std::endl; for (i = 0; i < MAX_SIZE; i++) { if (frequencies[i] > 0) { cout << i << "\t" << frequencies[i] << endl; } } } int main() { const int MAX_SIZE = 100; int size, i; int arr[MAX_SIZE]; cout << "Enter the size of the array: "; cin >> size; cout << "Enter the elements of the array: "; for (i = 0; i < size; i++) { cin >> arr[i]; } findFrequency(arr, size); return 0; }

## Output :

Enter the size of the array: 8 Enter the elements of the array: 2 3 2 4 3 2 5 4 Element Frequency 2 3 3 2 4 2 5 1
