How can I print a pythagorean triplet from an array?

Question

Suppose I have been given an array and I need to findout all such combination where a^2 + b^2 = c^2 then how can I achieve that?

C/C++ code would be helpful?

#include
#include
main()
{
  int arr[10]={1,3,4,5,6,7,8,10,11};

  int i,j,k,count=0;

  for(i=0;i<10;i++)
  {
    for(j=i+1;j<10;j++)
    {
      for(k=j+1;k<10;k++)
      {
        if(arr[i]*arr[i]+arr[j]*arr[j]==arr[k]*arr[k])
        {
          count++ ;
          printf("\npossible triangles %d,%d,%d",arr[i],arr[j],arr[k]);
        }   
      }
    }
  }

  printf("\n Number of possible Pythagorean Triplet are %d", count);
}
