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

[James G. <Jam...@Cl...>]

void my_number(void) is saying that the function my_number doesn't take any
parameters and doesn't return anything.

int my_number(void) returns a number, in the code use return ???; where ???
is either a magic number or a variable of type int.

E.g.

int another_function_call(int parameter1);

int my_number(void)
{
 return another_function_call(100);
}

Regards,

James.

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


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
