The Go for loop is similar to—but not the same as—C's. It unifies for and while and there is no do-while. There are three forms, only one of which has semicolons.

// Like a C for
for init; condition; post { }

// Like a C while
for condition { }

// Like a C for(;;)
for { }




1 is easy:

for i := 0; i < 10; i++ {
dosomething
}


2 is easy too:

for value = thisvalue {
dosomething
}



but how do i got to understand nr 3? o.O

If it's like for(;;) that just means it's an infinite loop i believe. no different then a while(true) loop

for
{

}

this. leaving out the condition will cause the loop to go into a infinite loops. and since some people want to do this on purpose (for gui's, listener sockets on servers, parsing) they can just short hand it for for(;;) even though if you accedently do for(int i = 0;;i++) it will cause an infinite loop as well.

Damn true story bro thanks

how could i forget that?

if you declared an int and incremented it in an "infinite" for loop, would it eventually crash once it exceeded int's range being 2,147,483,647? Would take a while but still..

not sure. should try and find out lol. also it wouldnt take that long un limited loops are pretty fast.

I'm trying it atm out of curiosity lol. It's gonna take at least a few hours o_o..

did you put sth in the Task-Part of the loop?

system out's and anything else slow down as hell

im pretty sure he is just doing what i said and incrementing an integer inside a for loop without a condition.

better than



because that'd be slow as hell
