Code:

#include <stdio.h>

void FizzBuzz(int x);    //Header of the function

int main(void) {
    int x;                 //cannot declare a variable in the condition of the loop (valid in C++, java but not i C(95 ?)
    for (x=1; x<=10 ;x++){
        FizzBuzz(x);
    }
    return 0;
}

void FizzBuzz(int x) {                //the function
    if (x % 3 == 0){ // Or (!(x % 3))
        printf("%d : Fizz\n", x);
    }
    if (x % 5 == 0){ // Or (!(x % 5))
        printf("%d : Buzz\n", x);
    }
}

I correct it... It miss a lot of {} (after the if and the for), I show x when fizz or buzz is found and add the stdio library

I specifically left out the brackets because they are unnecessary, because it's a single line of code inside the if / for, and that is allowed in C. I was thinking about that, and it does look nicer without them...

The initialization of the variable inside the for loop? Like I said, weak C-foo. I did C++, not C.

However, switching around the order of the functions made little sense, and you actually messed up the FizzBuzz function. That final printf('/n') is seperate for a reason... So, my suggustion would be to put the number in the final printf statement, along with the newline. So...

Code:

if (blah)
   printf("Fizz");
if (blah2)
   printf("Buzz");
printf(": %d\n, x);
