I have installed GMP using the instruction on this website: http://www.cs.nyu.edu/exact/core/gmp/ Then I looked for an example program using the library:
#include <iostream>
#include <gmpxx.h>
using namespace std;
int main (void) {
mpz_class a, b, c;
a = 1234;
b = "-5678";
c = a+b;
cout << "sum is " << c << "\n";
cout << "absolute value is " << abs(c) << "\n";
cin >> a;
return 0;
}
But if I compile this using the command: g++ test.cpp -o test.exe, it says gmpxx.h: no such file or directory. How can I fix this? I am kind of new to this. And I am using MinGW.
