Question

Confused about going through this C program. Thank you

Program Specifications:

***********************************************

** MAIN MENU **

***********************************************

A) Enter game results

B) Current Record (# of wins and # of losses and # of ties)

C) Display ALL results from all games WON

D) Display ALL results ordered by opponent score from low to high.

E) Quit

Your program will have a menu similar to the example above. The game

results will simply be the score by your team and the score by your

opponent. The user will enter a single game result at a time. This

assignment requires the use of a 2D array. You will not need the date of

the game or the names of the teams. All cases will be written within user

defined function. Functions should be used as much as possible.

YOU CANNOT:

Use global variables, in this or any program ever.

Use goto statement(s), in this or any program ever.
