REPEATED ARRAY

• Problem Description

  
  program to read elements in an array and find frequency of each element in an array. C Program to count the occurrence of each element in an array.

• CODING ARENA::

• #include <stdio.h>

  int main()

  {

    int arr[100],freq[100];

    int size,i,j,count;

    scanf("%d",&size);

    for(i=0;i<size;i++)

    {

      scanf("%d",&arr[i]);

      freq[i]=-1;

    }

    for(i=0;i<size;i++)

    {

      count=1;

      for(j=i+1;j<size;j++)

      {

        if(arr[i]==arr[j])

        {

          count++;

          freq[j]=0;

        }

      }

      if(freq[i]!=0)

        freq[i]=count;

    }

    for(i=0;i<size;i++)

    {

      if(freq[i]!=0)

      {

        printf("\n%d occurs %d times",arr[i],freq[i]);

      }

    }

    return 0;

  }
