Can we create a c++ program without main function?

Answer 1

"No you cannot unless you are writing a program in a freestanding environment (embedded environment OS kernel etc) where the starting point need not be main()

As per the C++ standard main() is the starting point of any program in a hosted environment."

Answer 2

#define sample main
int sample() {
// Your code.
return 0;
}
will work.

Answer 3

You can, but atleast I prefer not to do it in Code::Blocks, as there the main is important.

Any other function will return you a warning - Undefined Reference to WinMain()...

But yes, the code may still run.

And I personally prefer a code without warnings...

Answer 4

No. The main function(as the name suggest) is the main function. Without it its like there is no function to function. Lmao

Answer 5

You don't need this in swift, which is a mix of objectiveC and C++

Answer 6

Yes, It would raise an error or be ignored, I think
