Hi,
I'm writing a library in C++ which is supposed to be used by people using C.
One function I have must return a string to users which is arbitrary length.
The user must be able to use this string as "char *" so I was wondering if
the following construct is safe:
char *Func()
{
static string str;

me as I state what I know:

pushed on stack. this contains the arguments this function was called
with, address to return to after return from this function (the location
in the previous...

Hi,
I'm having a problem with my program and I think it stems from me not
understand how to call a function and return a int value to main.
What I have to do is create a program that runs through the numbers
and find the perfect numbers and list their factors. I cannot use
pointers or a table array or formulae. And I need to have a...

i Group,
to my understanding, defining a function parameter as "const" means that
the function is not going to change it.
Why does the compiler says "return discards qualifiers from pointer
target type" when I *access* a member of an argument defined as const?

I am trying to adopt a model for calling functions and checking their return
values. I'm following Scott Meyer's recommendation of not over-using
exceptions because of their potential overhead.
