This is very simple.
For(blah)
If(blah)
{
Do blah
}
Simplifies to
For(blah)
If statement doing blah
You see?
The for loop only repeats one item, ever. It's just that, most of the time,
that one item is a block noted by an open and closed
brace, but otherwise it can be any other one item, like another for loop, an if
statement, a single statement, or so on.
Take care,
Sina

Subject: for loops without braces?
Hi all,
I am desperately trying to understand Prim's algorithm. I have found it in
pseudocode and C code, but in both examples they use for
loops without braces, so it might be:
for(i=0; i<4; i++)
if(i%2==0){
print(i);
}
Obviously this is understandable, but when you mix it into other code it
becomes much harder to tell what is going on. First, how
can one do this syntactically and have it be correct? Second, what is the rule
to figure out where the loop ends if it is not in
braces? The C compiler must have a way...
