Hey guys. Function problem.

Okay, so I'm fairly decent at coding PERL, i just hate regex, and that's the only thing holding me back from mastering perl. But, this is my first post, which is why i said that, because i do have a little bit of experience programming, probably far from the average user on here lol, butw w/e... moving on.

Okay, I'm heaving a problem moving from a function to another. I could clearly tell, that i was doing it wrong, while making this program, so i decided to stop it, and at least get it to run, without errors, which is what i did. So, please don't make fun of me because its a stupid program/coded poorly. anyways here it is:

Code:

---

#include "stdio.h"



int guessednumber;
int magicnumber = 32;

int main() {

printf("\nGuess your number: ");
scanf("%d", &guessednumber);
int numberwork;
}




 int numberwork() {
    if (magicnumber == guessednumber) {
        printf("\n\nHoly ...., good job.");
    }

    else if (magicnumber > guessednumber) {
        printf("\nToo Low");
        int main();
    }

else if ( magicnumber < guessednumber) {

    printf("\nToo high.");
    int main();
}



}

---

The functions were originally "main()" and "numberwork()". but i kept getting errors. they said something like "ISO C++ forbids declaring something, blahblahblahblah..." I had the exact error, and i googled it, but only saw stuff about fixing headers, not to mention it was in C++. Oh yeah, and I'm using the MingW compiler, but im probably gonna download GCC tomorrow, cuz its what i used to use in linux. So, yeah, there it is... any help is greatly appreciated, and hopefully i can hang around here and learn a lot of stuff.

to call a function

Code:

---

numberwork();

---

The MinGW compiler IS GCC. I have noticed that when compiling a single file, Code::Blocks will ignore the filetype and seems to always use g++, but I assume that's because I haven't figured out the right magic setting yet.

Calling a function is just like perl -- numberwork().

You can't call main yourself (well, you can in C, but not C++, hence the message). You shouldn't anyway. If you know perl, then you know loops, so use a loop.

1. Include the prototype of the function where global variables have been declared.
2. Call the function as numberwork();
3. Dont call main from other function, either return a value or simply dont do anything.
By the way my question is what's the difference between "stdio.h" and <stdio.h>?

#include "" -- searches the local directory for the header first, then include paths.
#include <> -- the reverse of above.

Alright. I just realized that I had left numberwork as "int numberwork;" while trying move to it. I had originally had it "int numberwork();", and it wasn't working so i removed the parentheses, and apparently forgot to put it back. and whoever said something about using loops... You're absolutely right lmao. Idk what i was thinking, I mean it was like midnight, and I have ADHD so my medication wasn't working anymore, but still... that was dumb of me. But, you're saying that i should probably use the project thingy, for C, cuz it will actually use the C part of it?
