Game of 21. A lot of Errors :(

I don't know what is wrong with this. And the IDE I'm using is Visual Studio 2008.

What are the errors? Apologies but you probably won't find many people who will compile the code for you just to see what the problems are.

error C2040: '==' : 'int' differs in levels of indirection from 'const char [2]'

I have like 17 of these errors.

line 16: void hit(int &);
line 44: hit(person);

then line 115: char hit = "y";
gcampton (859)
basically you have a function called hit, and your declaring a char called hit... won't work. call it something else...

with errors, always ignore all the other errors after the first, just look at the first few lines of errors, have a look at the first line number and go to that line... in this case line 115. then try and determine why it thinks hit is a pointer to int.

errors on lines 116-139 are redundant and are simply a result of this mismatch of names, if you change the name on the line causeing the problem (115) then the other errors dissapear.

Now my function name is hit and the variable name is playerHit but I'm still getting the same 15 error messages
gcarlson53 (9)
My program finally runs but there is something wrong with the hit function because it never asks me if i want to hit or not. Here is my current code:
