rock paper scissors help

[original4u]

Hi,
This is my first time on this forum so I want to thank you in advance for your help. When I submitted this program, i got the following error:

8.1: expected unqualified-id before '{' token
{
^
I tried fixing this in many ways to match the requirements given with no results.

I was also asked the following:
1. Write a function that returns the computers choice.
int computerChoice ();
2. Write a function that returns the users choice.
int userChoice ();
3. Write a function that prints the computer's choice.
void printComputerChoice ( int computer_choice );
4. The function should return 'u' if the user wins, 'c' if the computer wins, and 't' in the event of a tie.
char computeWinner ( int computer_choice , int user_choice );
5. Write a function to start a new game.
void playGame ()


Your help is greatly appreciated.

void playGame ();

The semicolon ends the playGame function right there. You don't need a semicolon when you're actually defining the function.

return type function name(parameters)
{
function statements;
return something if not a void function;
}

If userchoice and computerchoice are functions you are calling here, you need userChoice() and computerChoice(), otherwise they look like undeclared variables.

if(userChoice==1){
if(computerChoice==2){

These while loops appear to be outside of any function. Where do you mean to run these?

while(userChoice!=1 && userChoice!=2 && userChoice!=3)
while(userChoice ==computerChoice)

Edit: You can use code tags on the forum to make your code easier to read. :) There's a button with <> on it in the format tools at the right side of the post.
