Is it possible to include variables through using %c and such when you have strings saved into the array?

char *MainMenuNames[] = { "%c - Move Left", "%c - Move Right","%c - Move Up","%c - Move Down","%c - Back","%c - Confirm","%c - Show Stats","%c - Show Inventory","%c - Show Legend","%c - Show Controls"};

When I have something like this, is it possible to put something into the %c?

  • Use it as a format string to sprintf, maybe? Commented May 9, 2018 at 18:16
  • That's exactly what the printf family of functions does. printf itself prints to stdout, but you can print to a file, or even just assemble a string with snprintf and do with it what you like. Commented May 9, 2018 at 18:17
  • printf and such are runtime functions. You can't achieve their effect at compile time. Commented May 9, 2018 at 18:19

You can use the array element as a parameter to formatting functions like printf()

char *commands = "lrudbcsiln";
for (int i; i < strlen(commands); i++) {
    printf(MainMenuNames[i], commands[i]);
    putchar('\n');
}
