How do I make a variable equal the number returned by a function?

Question

I'm new to functions and I can't seem to figure out how to make a variable in a function return as a variable in main();

When I do:

int menu()
{
cin >> select;
return (select);
}

int main()
{
int x = menu;
return 0;
}

I get "invalid conversion from 'int (*)()' to 'int' [-fpermissive]

This code has also been very simplified but that's the idea, how do I get this variable to equal the value that my function has returned?

`int x = menu();` Declare `int select;` in `menu()` You're Welcome ! — P0W, Nov 01 '13 at 13:49
You should read [The Definitive C++ Book Guide and List](http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list). It list books you might need. — Some programmer dude, Nov 01 '13 at 13:51
#include int value(){ int select = 4; return select; } int main() { int x = value(); std::cout< — OOkhan, Nov 01 '13 at 14:02

int menu()   
{
   int select;
   cin >> select;
   return select;
}

int main()
{
   int x = menu();
   return 0;
}

Declare select before using it.
Add () to the call to menu.
(optional) remove the unnecessary parentheses around select in the return statement.
