Question

This is my code :

#include <iostream>
using namespace std;

int main (int argc, char* argv[])
{
  int frstNumb = atoi (argv[1]);
  int scndNumb = atoi (argv[2]);
  int sum = 0;
  sum = frstNumb + scndNumb;
}

Okay, now its working for integers. What do I must do so I can put e.g. “2.5 and 1.2” in my parameters? This program won’t calculate that kind of numbers. Help?

Thanks

Yep– you want atoi().

int frstNumb = atoi(argv[1]);
int scndNumb = atoi(argv[2]);

I’d suggest googling atoi() to see how it works, it will probably help you in the future.
