Yes.
It is somewhat syntax of programming. But when program runs,device known as pre-processor process statements before main function. So when we use that function inside main function it will get idea and run directly without showing any error. So for compilers simplicity and fast execution purpose it is necessary to declare function before its use.
To return the exp. or const to the main fumction.
void display is the function name in which we want to perform some task or it might be to display something. But it has got its residence in the main() function that means that function's inputs are being supplied from the main(). void doesn't return anything so function call is made in main() which doesn't return anything back to it.
The function already exists in PHP and is even called max(); Otherwise use: function max ($one, $two) { return $one > $two ? $one : $two; }
It is not clear why would you want two functions with the same name. If you simply like the sound of word 'main', you can have one static 'main' function in each source files, but those functions won't be callable from outside.
Because if you donot use main function in c program, the compiler willnot execute the program.C compiler starts execution from main function itself.
Yes
Yes.
The IF function is the main function to do it and you can also use other logical functions, like the AND function, the OR function or the NOT function.
No. You can only have one main() function in a C or C++ program.Note:If this question means "Will the OS start two threads/processes if I have two public scope 'main' functions in my program?"then the answer is "No, even if you could link such program, which you cannot."
