Help User-Defined Function - part 2

  #1  
Apr 4th, 2007
Hey everyone, this is a big one.

The question has asked that I define functions and then write the function main to test the functions I wrote. I keep getting the following error at my first cout in main:

error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'void' (or there is no acceptable conversion)

I'm not sure what this is saying.
In addition, I need help with defining two of my functions and writing code to test them. They are as follows:

1. Write the definition of the function nextChar that sets the value of z to the next character stored in z.

2. Write the definition of the function funcOne that prompts the user to input a number. The function then changes the value of x to 2 times the old value of x plus the value of y minus the value entered by the user.

Now, with #2 I'm pretty sure I have the function defined right, though I don't know how to test it. #1 though, I have no clue how to define that function, though I did attempt it =/.

Could someone look through my code, and let me know if they notice any huge mistakes? This is our second chapter on user-defined functions, so I'm still learning about call by reference and whatnot. I have commented my code minimaly to assist you in finding the parts I'm having a tough time with.

Thanks guys! :mrgreen:
