Answer to Question #36497 in C++ for Gs

Question

Can anyone tell me the error and its correction

#include<iostream.h>
#include<conio.h>

int sqr(int num , int div);
int main()
{
int num;
cout<<"enter ";
cin>>num;
int div = num;
int sqrt;
sqrt=sqr(num,div) ;
cout<<sqrt<<endl;
return 0;
}


if(div==1)
{
return 1;
}

else
{
if((num/(div*div))%1!=0)
{
div=sqr(num,div-1);
}

if((num/(div*div))%1==0)
{
return div;
}
}
