Tricky , yet interesting question

Greeting ranchers

I was asked an interesting question about programming recently and I want to share with you all.

"Without using any semi-colons in the entire code write a simple application in C/C++ which simply prints "Hello World" on the console "

Of-course I know the answer but I want to see your responses first before I share the solution

Here's a better question...

Why would you want to?

No particular reason . Of-course no one wants to do that , it was just a challenge that my friend gave to all of us and we were coming will all sorts of weird solutions , in the end he showed us how to do it So I thought to ask here on the ranch as well

Since this is a java site, wouldn't the question be better if the challenge was for java?

And BTW, here is the solution in Java...

public class HelloWorld {

	public static void main(String[] args) {
		System.out.println("Hello World")\u003b
	}

}

For C/C++, I would try to do something similar with the C preprocessor.

public class App {
static{
if( System.out.append("hello world").checkError() ){}

}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

}

}


This is how you do it in Java

That's an even better idea !

You are using the Unicode for semi-colon here, but the requirement was to avoid the use of a semi-colon at all . Still I like your approach !

Great approach Mike .

The solution in C is similar to this one, i.e to wrap the console writer within an if statement and an empty if block ! And truly your code is without any semi-colon at all ! Great !

wow... great and thanks for sharing
