C++ : integer constant is too large for its type
- by user38586
I need to bruteforce a year for an exercise. The compiler keep throwing this error:
bruteforceJS12.cpp:8:28: warning: integer constant is too large for its type [enabled by default]
My code is:
#include <iostream>
using namespace std;
int main(){
unsigned long long year(0);
unsigned long long result(318338237039211050000);
unsigned long long pass(1337);
while (pass != result)
{
for (unsigned long long i = 1; i<= year; i++)
{
pass += year * i * year;
}
cout << "pass not cracked with year = " << year << endl;
++year;
}
cout << "pass cracked with year = " << year << endl;
}
Note that I already tried with unsigned long long result(318338237039211050000ULL);
I'm using gcc version 4.8.1
EDIT:
Here is the corrected version using InfInt library http://code.google.com/p/infint/
#include <iostream>
#include "InfInt.h"
using namespace std;
int main(){
InfInt year = "113";
InfInt result = "318338237039211050000";
InfInt pass= "1337";
while (pass != result)
{
for (InfInt i = 1; i<= year; i++)
{
pass += year * i * year;
}
cout << "year = " << year << " pass = " << pass << endl;
++year;
}
cout << "pass cracked with year = " << year << endl;
}
