Original Message 1/6 13-Sep-98 @ 12:26 AM - How do I program ;
I know this has nothing to do with music, but since I'm here I might
as well ask. Any C or C++ programmers know how a function can
take in 3 values a,b,c and return the values as c,b,a ??
I don't understand this because I thought a function can only return
one value at a time.
Here' the question as asked:
Write a function that will return the numbers in reversed order; i.e.
a,b,c, will now be printed c,b,a, on return from the function.
Anybody understand this.
I know this is way off topic but its better than a stupid comment.
Thanks

I thought if you wanted to return more than one parameter you had to use a procedure instead of a function. Im probably wrong though. Dont know my ass from my elbow with C.

Well, in a language like Pascal, you can send variable parameters to functions, or procedures, and then modify them... C only allows value parameters to be sent so they cannot be modified by the function. The way around this is to use pointers (groan) which are basically the memory addresses of the variables you want to change. Buy a book on C for the syntax! You need to stick a * in front of the pointer to access the variable instead of the memory location... Fuck am I bored

Dunno about c, but in c++ you can also use references to variables so you don't have to hassle around with pointers.
BUT... I really think this kind of conversation doesn't belong here, there are lots of nice newsgroups and sites dedicated to programming.

I think it goes a little something like this:
void ReverseOrder(int *a,int *b,int *c)
{
// b is not really needed now is it!
int dummy;
dummy=*c;
*c=*a;
*a=dummy;
}
now suppose you have int variables d,e,f
you would call the procedure like:
.. bla
int d=3;
int e=5;
int f=7;
ReverseOrder(&d,&e,&f);
//d=7, e=5, f=3
void ReverseOrder(int *a,int *b,int *c)
{
// b is not really needed now is it!
int dummy;
dummy=*c;
*c=*a;
*a=dummy;
}
now suppose you have int variables d,e,f
you would call the procedure like:
.. bla
int d=3;
int e=5;
int f=7;
ReverseOrder(&d,&e,&f);
//d=7, e=5, f=3
