Use [code][/code] tags please.

You declare two variables with the identifier 'd', one string, another int.

You don't need a function prototype for main.

Red is not an array (red[r]).

Neither is blue (blue[r]).

You create a couple red and blue arrays (incorrectly) after using the arrays above

1
2
3
4
 
int red[0] = {-50};
int red[1] = {50}; // red is already declared
int blue[0] = {-100};
int blue[1] = {100}; // as is blue


play () doesn't return anything (it should return something of type int).

You are missing a brace at the end of DETERMINE

RULES is missing a brace as well.

system("Pause"); already has a message saying to press any key.

You shouldn't call main from another function, that is what the return statement is for, to return something from the current function to the function which calls it.

Your post is really messy, so these are the few that stick out to me. If you would place the code in [code][/code] tags and the errors in [output][/output] tags, it would help greatly as it would be much easier to read. Also lessening the capatalized identifiers would be easier on the eyes as well (for me at least).

And you should note that C++ identifiers are case-sensitive

So even after you fix all your syntax errors, your program will fail to link as the required entry-point will not be found. It must be (all lowercase)

1
2
 
int main()
{


As Danny Toledo said, main does not need a prototype. But MAIN is not main!

And all upper-case identifiers are usually reserved for #defines (and sometimes typedefs). Function names are usually lowercase, lowerCamelCase. or UpperCamelCase (used consistently!).

Your global variable, red, is not an array. Therefore, it's syntactically illegal to use the sub-script ([...]) operator on it.

Braces ({...}) cannot be used in this manner. Braces are only used for initialization lists and body scopes. You need to either remove the braces or replace the braces with parentheses. Also, as I said above, you've used red as an array, which it is not.

You've forgot to place the << before endl.

EDIT : wow, I must have forgotten to refresh the page or something; I thought there were no replies to this when I posted, but boy, was I wrong.

No need to duplicate the errors already presented by the above posters

red is not an array. You need to declare it as an array at the point of declaration. For example:

1
2
3
4
5
6
7
8
9
10
11
12
13
 
// Declare an array of 3 integers and initialize each element
// with a random value (hand picked).
int Red[3] = 
{
    37, 29, 28
};

int main( )
{
    // Use the sub-script operator ([...]) to access individual
    // elements of the array.
    Red[0] = 10;
}

Note that indices are zero-based. This means that the first index (first element) is 0, the second is 1, and so on.

That's because you need to explicitly tell the program to wait. You can do this with either function:

1
2
3
4
5
 
int Wait( )
{
    std::cin.ignore( std::numeric_limits< std::streamsize >::max( ), '\n' );
    return 0;
}

Or

1
2
3
4
5
 
int Wait( )
{
    std::cin.get( );
    return 0;
}

The first option requires the user to press enter. The second option requires the user to enter a character then press enter. The choice is yours.

A final note: Never call main( ). Only the operating system should call main( ).

That's because there's no chance for the user to input anything. You need a cin statement to get "rules" or "play"

How does that compile? When I call main () in main, I get:

Error E2120 main.cpp 6: Cannot call 'main' from within the program in function main()


If I try calling it from another function, I get the same error, only "main ()" is replaced by the name of the function trying to call it.

As it has already been stated, you need to get input from the user to determine whether he/ she wants to play or see the rules.

cin.get (); only requires the user to hit enter. If you are getting input data before the use of the function (cin>> and getline as well I think), use cin.clear (); or cin.sync (); (or both) before cin.get ();

A quick jump back to the full code, there is also no need for function prototypes if you define the functions before main (or whatever function will be calling it).

Danny, std::cin.clear( ) only clears the flags set by std::cin; it doesn't actually manipulate the characters within the stream.

I do admit, however, that I was wrong about std::cin.get( ).
