Command line arguments

[sekmo]

Hello, my professor wants us to get the program to take in an ASCII value and convert it into binary and vice versa. But she wants us to take it in as a command line argument. I have no idea how to do command lines. I've watched videos and read textbooks but cannot wrap around it besides the basics. Plus, she wants it so -a will correspond to the ASCII and -b will correspond to the binary. And I do not know how to account for that at all. Please help!

argc and argv are the command line arguments:

#include <iostream>

using namespace std;

int main(int argc, char* argv[]) // This comes from the command line
{
  for(int i = 0; i < argc; ++i)
  {
    cout << argv[i] << endl;
  }
  return 0;
}
