Case Switch issue

Hey Guys,

Trying to create a case switch for my separate functions...

Here it is:

Code:

---

switch(i)
            {
            case 0: IScd(int argc, char *argv[]); break;
            case 1: IShelp();break;
            case 2: kill_main(int argc, char *argv[]); break;
            case 3: ISls(args); break;
            case 4: ISps(); break;
            case 5: ISpwd(); break;
            default: break;
            }

---

All the functions are there BUT it wont compile: error: syntax error before "int"....

Any ideas?

I think Im doing it right...

Ahh ok - so basically you cannot have Ints and Chars in the same thing....what way round it is there?

When you call a function, like say sin(5.5) -- you just pass the thing to the function, you don't go trying to tell the compiler what kind of thing it is. The compiler can see perfectly well for itself that argc is an int, you don't need to tell it so.

Code:

---

switch(i)
{
        case 0: IScd(argc, argv); break;
        case 1: IShelp();break;
        case 2: kill_main(argc, argv); break;
        case 3: ISls(args); break;
        case 4: ISps(); break;
        case 5: ISpwd(); break;
        default: break;
}

perhaps?

That gives the complier error:

sample2.c:93: error: `argc' undeclared (first use in this function)
sample2.c:93: error: (Each undeclared identifier is reported only once
sample2.c:93: error: for each function it appears in.)
sample2.c:93: error: `argv' undeclared (first use in this function)

Well, presumably you know what you want to pass to IScd and ISls and so on; so do so. If you want to use the command line arguments, then make sure you put argc and argv in the declaration of your main() function.

pc_doctor, I find it perfectly logical that you must pass existing variables or values to a function.
Can you give someone a fruit that you do not have? No! Then why should a compiler be able to call a function with variables or values that do not exist?
Think about it!

Lol - Yeah i know...Im blaming it on not enough sleep and getting stressed about all these elements of my program...

LS,
KILL,
PS,
PWD,
CD

All combined into a shell.
