WAP to find the frequency of numbers present in a list. Solve in C and C++

eg: 1,2,2,3,10,90,88,47,58,83
Output: 0-10=5

11-20=0

      Using C

      

      

#include <stdio.h>

int main()
{
//Initialize array
int arr[] = {1, 2, 2, 3, 10, 90, 88, 47, 58, 83};
int i, j;
//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(i = 0; i < length; i++){
int count = 1;
for(j = i+1; j < length; j++){
if(arr[i] == arr[j]){
count++;
//To avoid counting same element again
fr[j] = visited;
}
}
if(fr[i] != visited)
fr[i] = count;
}
//Displays the frequency of each element present in array
printf("---------------------\n");
printf(" Element | Frequency\n");
printf("---------------------\n");
for(i = 0; i < length; i++){
if(fr[i] != visited){
printf(" %d", arr[i]);
printf(" | ");
printf(" %d\n", fr[i]);
}
}
printf("---------------------\n");
return 0;
}

      Using c++
      

      #include <bits/stdc++.h>
using namespace std;

// Main function to run the program
int main() 
{ 
    int arr[] = {10, 30, 10, 20, 10, 20, 30, 10}; 
    int n = sizeof(arr)/sizeof(arr[0]); 

    int visited[n];

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

        if(visited[i]!=1){
           int count = 1;

              }

            cout<<arr[i]<<" occurs at "<<count<<" times "<<endl;
