A question regarding for loop

[moijes12]

Hi

I have a question regarding the for loop.

Suppose I write the below code :

#include <stdio.h>

int main(){

for( ; ; )
printf("Hello World\n");

return 0;
}

Now I am yet to try the above code but I assume the above code should
not have any output because there is no test expression.So the test
expression should evaluate to 0(False) rather than 1(True).

Please let me know what you think of this.

regards
moijes

You really need a good book about C. You won't be able to learn a
programming language by guessing what the various constructs do (even if
you the post here). A good text will simply tell you.

Please let me know what you think of this.

As it happens, a missing text expression is a for loop is taken to be 1,
not 0.

What does your C reference book say this construct does?

Please let me know what you think of this.

I'm half inclined to think you're a troll.
