I have no idea what you just asked. Be more specific.

Oh, is this the "hello world without a semicolon" problem with a C++ twist?
#include <iostream>
int main()
{
if ( std::cout<<"Hello, world!"<<std::endl ) {
}

that can't be correct, Na I thought you told me int main() has to return something? Nothing was returned :evil:
hahahaha...seriously, don't you have to put something inside the braces?

>Nothing was returned
Standard C++ returns 0 by default. Returning from main can be tricky, especially if you switch languages and work with legacy code a lot. In pre-standard C++ you need to explicitly return a value. In C89 you need to explicitly return a value. In standard C++ and C99, you can omit the return value and 0 will be returned automagically.
However, because C99 isn't widely implemented yet, everyone follows the intersection of C89 and C99 to avoid nonportable code during the interrim of changing from old standard to new standard. Since standard C++ is well implemented now, it's safe to omit the return value, but many still do it explicitly anyway as a matter of style and consistency.
My preference is to omit the return value unless I return failure, then I return success explicitly as well:
>don't you have to put something inside the braces?
No, an empty block is legal. It's roughly equivalent to:
But that uses a semicolon, so it's not a valid solution for the problem.

return EXIT_SUCCESS; // And success here
}No, an empty block is legal. It's roughly equivalent to:
if ( something ) ;

If you want to just output anything without semicolon at the end ...then u can simply shift the semicolon to the next line i.e
1.printf("hello world")
2.; // semicolon is used to terminate statements so it can be shifted to next line
or
1. cout<<"Hello world"
2. ;

isnt semicolon at the end of any statements a required syntax in C and C++??
if thats so, that cant be possible unless modifying the whole language(Not C anymore)..

Not necessarily, it was a trick question. See this.
