hello friends,
what is the difference between these two functions
Code:void menu(){ printf("function 1\n"); }
and this functionnormaly if we want to add argument to a function its like thisCode:void menu(void){ printf("function\n"); }
Code:int Add(int x,int y) { int sum; sum = x + y; return sum; }
> what is the difference between these two functions
There isn't any difference.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.

I prefer the second function, as it's input argument is mentioned.
Actually, there is a significant different. In C in particular, and not in C++, if a function declaration/definition argument list is entirely empty, it means that the function can take any number of any type of arguments. For example:
Code:void bar(); void foo(void); // Later, inside another function bar(); bar(1, "a", b); // Compiles just file foo(); foo(1, "a", b); // Compilation error!
Devoted my life to programming...
One is a void and one you should avoid.
