{

    int num[5]={16,29,45,49,4};

    int iVar,k, count=0;

    float fVar;

      for  (k = 0; k<5; k=k+1)

    {

    fVar=sqrt(num[k]);

       iVar=fVar;

     if(iVar==fVar)

        {printf("%d is a perfect square.\n",num[k]);

        count++;}

    }

 printf("count of perfect square=%d \n",count);

    return 0;
