Howto execute a command in C if argv[1] is equal to -A

Hi,

I want to execute a command when the first argument of a C program I am writing, is equal to -A.

Can someone show me how that can be done? I am starting with C and I am unable to achieve this myself.

Thanks

Ben

maybe like this?

Code:

int main(int argc, const char *argv[])
{
  if (strcmp(argv[1],"-A") == 0)
    system("command...");
}

Thanks!! It works indeed.

Another function you might want to look into is popen(), if you're
familiar with file I/O it will be a breeze.
