You need to declare it first. A function declaration is made of three parts:
The kind of data the function returns, I.E. void, int, etc.
The name of the function, I.E. helloWorld.
The list of parameters in parentheses, I.E. (A as int, B as char)
For an example, here it is:
void helloWorld();
Now, to put something inside the function, you can write the following:
void helloWorld()
{
printf("Hello world!");
}
