Use two loops. In the outer loop, pick elements one by one and count the number of occurrences of the picked element in the inner loop.

This method doesn’t use the other useful data provided in questions like range of numbers is between 1 to n and there are only two repeating elements.

#include
#include
void printRepeating(int arr[], int size)
{
int i, j;
printf(" Repeating elements are ");
for(i = 0; i < size; i++)
for(j = i+1; j < size; j++)
if(arr[i] == arr[j])
printf(" %d ", arr[i]);
}

int main()
{
int arr[] = {4, 2, 4, 5, 2, 3, 1};
int arr_size = sizeof(arr)/sizeof(arr[0]);
printRepeating(arr, arr_size);
getchar();
return 0;
}

my answer is 9 this can be explain with small example so that u can easily understand ++i will increment the value of i, and then return the incremented value.

i = 1;
j = ++i;
(i is 2, j is 2)
i++ will increment the value of i, but return the original value that i held before being incremented.

i = 1;
j = i++;
(i is 2, j is 1)
