Thread: main function arguments

If I'm getting this straight, you want to pass two values to your program and then create arrays of those sizes:

Code:

#include <cstdlib>

int main(int argc, char *argv[]) {
  int *p;
  int *q;

  if (argc == 3) {
    p = new int[ std::atoi(argv[1]) ];
    q = new int[ std::atoi(argv[2]) ];
    ...
  }
}

There's nothing about arrays in there...

Code:

#include <iostream.h>
#include <stdlib.h>

int main(int argc, char* argv[])
{
  int p,q;
  if(argc>0 && argc<3)
  {
    p=atoi(argv[1]);
    q=atoi(argv[2]);
  }
  else
  {
    exit(1);
  }
  return 0;
}

I hope that's what you wanted...

from the looks of it, you're trying RSA encrption. A little piece of advice... the numbers get too big to handle in regular C so you might need a library that can handle these large numbers.
