I did a few searches but I'd just like to quickly confirm with the Guru's here:
Is there EVER a time where a semicolon ';' is put after a closing brace '}' ?
I ask only because I use CodeVision AVR and it has some "library" statement prototypes that you can click on to have pasted into your code. Some of these have semicolons after the closing brace. This is confusing me. I've always thought the closing brace was sufficient.

yes. When declaring a struct or union, or an initialized array.
unsigned char my_array[4] = {1,2,3,4};
struct my_struct {
unsigned char a,b;
};
A colon after a brace doesn't hurt, but it is superfluous. I might be a hold over from a very old C style.
Edit: I guess your right, glitch. I hadn't considered those cases.
It always pays to ask even the dumbest of questions! Thanks!
Wouldn't the semicolon in this code cause a "no corresponding IF" error during compile?
if(a==b) {
do stuff
};
else {
do other stuff
}
In other words the semicolon de-couples the 'IF" from the "ELSE" . I could be wrong.... it's been known to happen... :lol:
Yes, sgomes. The compiler should issue an error as else is no valid start of any C statement.
AVR-GCC says this:
../main.c:17: error: parse error before "else"
In 'C', the semicolon is a statement terminator
Also, a null statement - eg, just a semicolon - is legal in 'C'
Thus you can put as many semicolons as you like anywhere that any statement would be allowed - but no statements are allowed between an 'if' clause and its 'else' clause.
Well said!
