Where i am wrong?

#include <iostream>
#include <cmath>
using namespace std;
int main ()
{
    double n,i,a,f,m;
    cin>>n;
    for (i=1;i<=n;i++)
    {
        cin>>a;
        m=sqrt (8*a-7);
        f=int (m);
        if (m==f) cout<<"1";
        else cout<<"0";
    }
}

f = int(m);

f = ceil(m);

m=sqrt (8*a-7);

m = [sqrt(8.0*a-7.0)-1.0]/2.0
