#include <iostream>
#include <fstream>

using namespace std;

int main
{
    int num1, num2;
    ifstream infile;
    ostream outfile;

    infile.open("input.dat");
    outfile.open("output.dat");

    infile >> num 1 >> num 2;

    outfile << "Sum = " << num1 + num2 << endl;

    infile.close()
    outfile.close()
    return 0;
}

this is what i did and when i compile it, i got this error that said

error C2470: 'main' : looks like a function definition, but there is no parameter list; skipping apperent body

please dont hate me :( i am new at this computer science....
