Difference between main and void?

[yohomes]

Im watching the C++ video tutorials and at first he started out using int main () { to start the program but switches to void main () { whats the difference between the two?

Also how does he get the console window staying up without the cin get () statement?

The diffrence between Void and Int , is that the Void function doesn't return a value While the int returns,
it is more likely to use as the main function the void, but if you use the int , then you should put a returning value in the last row of the function.
Regarding to Keeping the window open you can use "_getch();" function.
Hope That I helped.
Have a nice DAY.

"void" is only usable with Microsoft's compiler. Since many people were using other compilers, I switched to "int," which is valid on all compilers since it is standard for C++. Initially, I used "void" because I thought it would be easier than having to explain the "return" statement to beginning programmers. This was the only non-standard C++ that I used, and now I avoid it entirely.

To keep the console window open, you can compile with using the "Start Without Debugging" option by pressing (F5 + Ctrl). Microsoft had that option in the menu until 2010 (you can still get it by selecting "Expert Settings" under the "Tool" in the menubar). Since Microsoft took that option out of the menu, I started to use cin.get(). Since this question was so common and has several facets, I created a blog post for it:
