Unexpected output of for loop

[Jishnu]

#include<stdio.h>
int main()
{
	for(;0;)
	printf("Hello");
	return(0);
}

This code should not give any output, but it is printing Hello once. I'm using TC++ 3.0. Is something wrong with the compiler?

If that is your code, then your compiler is broken. It does what it says with gcc.

But if this is your code (note the 1-character difference), then "Hello" is printed once.

#include<stdio.h>
int main()
{
	for(;0;);
	printf("Hello");
	return(0);
}

Now, did you paste what you tried, or did you recite from memory what you thought you tried?

[Jishnu]

No, I know that the semicolon at the end of for loop is not there. I am very much clear about that. I think that the compiler is faulty. I cannot perceive any other logical explanation. I posted to know if anyone thinks otherwise.

I just tried it with VC++ 2005 Express and TC (the original I think, dated 1989). Neither compiler had the problem you report.

Why?

>I think that the compiler is faulty.
And? Salem agreed with you if the code you posted is exactly the code you're running. What more are you looking for?

Turbo C Ver 1 also prints, so it's probably a bug at least through ver 3. Borland 5.5 works as expected.

As reported earlier I used TC Version 2.01 and it did not have that problem.

It is the first time that I came across a problem where it is the compiler's fault. So I just wanted to confirm.

That is exactly what I found.

I have not tested it on TC version 2.01. There may be a difference between different versions. No issues from my side.

>Why?

I sincerely want to know why not?

Since this is now a non-issue because it has been answered (and the specified for statement is really stupid to begin with), to stop the further useless posts this thread is closed.
