Re: C++ for loops

(1) The language specification requires them. (2) they separate initialization, condition, and increment statements.

Re: C++ for loops

in a normal loop you would have
for( i = 0; i < n; i++)

but in your code the semicolon simply states that it doesnt matter what the first section( i = 0) is.

[edit] What AD said. lol.

Re: C++ for loops

All of the sections are optional, so we sometimes end up with this: for(;;)
