[Dev-C++] sending and retrieving values from functions

[jag <won...@th...>]

hi,

i'm studying a tutorial that makes use of a function named my_number.

at the beggining of the code before the main loop it is declared as
follows:-

void my_number(void);

the code for the routine is called from within the main loop by the command
my_number();

my question is, if i wanted a return value for one of the values in the
function my_number what command would i use?

The tutorial explains the use of the term void in the code saying that it is
used when there is no return values!

Is it possible for anyone to explain how i might send or retrieve values to
the function my_number?

thanks,
jag

int f(void); //function that accepts no parameters and returns an int
int f(int x); // function that accepts an int and returns an int
void f(int x); //function that accepts an int and does not return any value

The simplest way to do this, would be to first of all, declare the function as

int my_number(void);

This is assuming you want it to return an integer.  Otherwise replace int with whichever type you want it to return.
If you are using c++ then the void in parenthasis is not needed.

then for the terminating line of the function

return somevalue;
where somevalue is a value or variable of the correct type.
