You are missing some semi-colons in your switch statement. Also this switch appears to be floating outside any function. That won't work:

switch(choice)
 75. {
 76. case 'a':
 77. case 'A': PrintMenu(char choice) <-----!
 78. break;
 

Then your prototype:

int EnterNumber(int ,int );

doesn't match the code for the function which has a single char argument rather than 2 ints.

There may be other errors. What you try to do is fix only the first error and then rebuild your program. The first error may cause the compiler to find other things wrong that maybe aren't wrong. Eventually by fiing the first error you will get a clean build. Then you can start the actual debugging.
