CNC PROGRAMMING

What the fuck is a CNC programmer and how do I learn it within a week?
I can't get an engineering job out of college so I want to claim to be an expert CNC programmer. There are like a million jobs for it.

#include <stdio.h>
#define NIGGERFUCK "niggerfuck"

int main() {
  printf("Hi %s", NIGGERFUCK);
  return 0;}
