How do I make it so that if you type something like "tr.exe -d" it will execute a certain function but if you type "tr.exe -s" it will execute a different function? Is there a good way or do I just use argv and if statements?
BTW I am using C and gcc compiler

if you are in Linux/unix environment, libgetopt might be available to you:

Using:
strcmp
if
else

You're talking about using command-line arguments.

#include <stdio.h>
int main( int argc, const char* argv[] )
{
  if (argc > 0 )
  {
    if (argv[1] = "-d")
    {
      //do -d stuff
    }
    else if (argv[1] = "-s")
    {
      //do -s stuff
    }
  }
}

Then parse it yourself. No big deal if your options are not extremely complicated. Refer to WingedPanther's pseudo-code.

You may consider using strcmp, stricmp, etc
