For(;;) logic with example

Question

I can't understand how does it work in programming logic. Can anyone explain it with an example? I want to know please help.

Answer 1

A for loop has a place to initialize variables, a place for an ending condition and a place to change variables basically.

for(int i=1; i<=10; ++i) {
// Do stuff
}

i increases up to 11, and then the loop stops, because the condition is not true anymore.

f(;;) just means that you leave all slots empty. You create no values, don't change them - and, most important, you have no condition, so the loop doesn't know when to stop.

Which means it'll just run forever (or until there's a break).

Answer 2

Exactly.

Answer 3

Do you mean for(;;) instead of if?

Answer 4

Yes sorry for mistake it will for(;;)

Answer 5

Oooooo you mean it will go for infinite loop right.

Answer 6
