What Does a Computer Programmer Do?

A Commuter Programmer creates the code for software applications and operating systems. After a software developer designs a computer program, the programmer writes code that converts that design into a set of instructions a computer can follow. They test the program to look for errors and then rewrite it until it is error-free. The programmer continues to evaluate programs that are in use, making updates and adjustments as needed.
