Need help with some C code, please.

First of all, there's a missing } at the end, but that might have been a copy/paste error when you posted it here.

From your indentation and missing } after main, it looks like you're defining FrenchToastForEveryone inside main. You also have a semicolon after it, separating it from its definition:

Code:

    void   FrenchToastForEveryOne ( void )[COLOR="Red"];[/COLOR]
    {
        printf ( "French Toast!\n" ); 
        
        
    }

After you've fixed that, you'll still have 3 errors:
Undefined symbols for architecture x86_64:
"_HardBoilThem", referenced from:
_main in main.o
"_MakeAnOmlet", referenced from:
_main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is just because you haven't defined those functions. Your declarations at the top are fine for forward referencing a function so you can use it in main if its defined further down, like your FrenchToastForEveryone function. The other two aren't defined and that's what its complaining about. You'd be better off putting empty functions and fill them out as you go, like:

Code:

void HardBoilThem() {
}

void MakeAnOmlet() {
}

 

1. What you posted will not compile. There's a closing parenthesis missing. As a result, I have to guess what your actually code is.

2. You cannot write one function (FrenchToastForEveryone) inside another function (main).

3. Assuming there is a closing parenthesis at the end, you didn't actually write one function inside another. The ";" after FrenchToastForEveryone (void) means this is just a repeated declaration of the function.

4. The linker tells you that three functions are missing. You need to write these functions before you can compile and run the program. Even if they just have an empty body.

 

As a habit I got into a while back is to add both of my {}'s at the same time. Then back up a few space and start to write my code between them. That way you are sure not to forget it since you already added it.

But the way you are approaching your learning is good, like I did. Take what you are learning, come up with your own ideas and write new code.

Reading the book is good. Doing the tutorials is better. Creating your own projects from the 2 is best.

 

You can set XCode to insert the } for you whenever you type { so that every block you begin has an end.
