Hi everone, I am new to C++, please help.
After I compile (using borland V5.02), I got these above prolem, please let me know what's wrong and this is my source code:

Thanks in advance.

First off, when you post in the future you should use the code tags to make it way easier to read.

Last time I checked your main() function has to return an int and you have it as a void function.

void main (void)
{
	mainProgram();
}

I don't know if its just because I use Dev-C++ and you have Borland.


You have a line in your mainMenu() function

cin >> "choice"; //this is wrong "choice" is not a variable
cin >> choice; //change to this

In mainProgram() function

char userChoice;
userchoice = mainMenu ();
switch (userchoice)

userchoice and userChoice are two different variables so watch out for typos

and

case 'E'
case 'e'

case 'E': //add a colon to both cases like you did above for all the other case statements
case 'e':

I'm not too sure why you made a function called mainProgram() when if you stuck it's contents into your main() function.

Thanks for your help. This is the first time, that's why I did not know how to post the right way, sorry.
I did the same thing like you said, but problem still happen, I do not know what's going on, could somebody please help???? I have to turn this one in tomorow.
Thank all you guy very much
This is new edit, but still got same error.

Thank you everybody, I got it, thanks god, I can beable to turn it in tomorow

Thank you everybody, I got it,

I cannot imagine that the above code would compile. One thing I spot is that you write while with a capital W (While). That won't compile for example.

Also: void main

thanks god

So did God give you working code then? :icon_wink:
