Question

I am using c++ to solve a problem. I need to find the factorial of 100 and find the sum of its digits. Because of the limitation of the variables in c++ I am using a header file called infint (https://code.google.com/p/infint/). It has its own function to convert an InfInt to a string. However I am getting this error:"Too many arguments to function call, expected 0, have 1." I am using xcode also.

My code:

#include <iostream>
#include "InfInt.h"
#define INFINT_USE_EXCEPTIONS
using namespace std;
int main() {
    InfInt result=1;
    for (int x=100;x>0;x--) {
        result*=x;
    }
    cout<<result<<endl;
    InfInt I;
    string sresult = I.toString(result);
    cout<<sresult<<endl;
    
    return 0;
}

I cannot include the full header code but you can download it from the link.

Part of header for toString:

inline std::string InfInt::toString() const
{//PROFILED_SCOPE
    std::ostringstream oss;
    oss << *this;
    return oss.str();
}

There are other references to the method in the header file but I believe this is the only important part.

Answer

Try:

#include <iostream>
#include "InfInt.h"
#define INFINT_USE_EXCEPTIONS
using namespace std;
int main() {
    InfInt result=1;
    for (int x=100;x>0;x--) {
        result*=x;
    }
    cout<<result<<endl;
    string sresult = result.toString();
    cout<<sresult<<endl;
    return 0;
}

Note that result is an InfInt object and that this object has a method toString() that returns a string representation of it.
