SHORT ANSWER

 

  1. Provide a general description of how to write a computer program.

 

Answer: To write a computer program, first a user must know what needs to be done, and then he or she must plan a method to achieve this goal, including selecting the right language for the task. Many computer languages are available; the language the user selects depends on the problem being solved and the type of computer he or she is using.
