Help, why I have Compillation Error?

Posted by sas 3 May 2007 21:37

#include <iostream>
#include <math.h>
using namespace std;

long int c,i,a,s;

int main ()
{
    cin>>a;
    s=0;
    for(;;)
    {
        s++;
        a-=pow(int (sqrt(a)),2);
        if(a==0) break;
    }
    cout<<s<<endl;

    return 0;
}

a-=pow(int (sqrt(a)),2);
-> a-=(int)pow(int (sqrt((double)a)),2.0);

Error here:
a-=pow(int (sqrt(a)),2);
you must write
a-=pow(int (sqrt((double)a)),2);
P.S. your algorithm gives WA#5!
