I guess the word got a little too confusing... :)
I just meant that even thou the call-by-reference feature is not there in C.
We can use pointers to get similar results.

we know all these definitions.
but i think the doubt was regarding the word simulate as we consider call by
reference an internal part of C
but your statement means that it is a concept of C++, but we just simulate
it in C using pointers. Am I correctly interpreting it?

We can say call-by-reference is where changes in formal parameters are
reflected in actual parameters.
call-by-value is where changes in formal parameters are not reflected in
actual parameters.
However when u have something like
int x=10;
f(&x);
void f(int *p){ *p = 20;}
changes in p(formal para
Shashank,
In C++ we implement it thru reference variables
in the function call we can say func(x);
in the definition we have, func(int &a)
whatever changes we make to a in func() are reflected back in x in the
calling function
In C, we can simulate i t through pointers
call : func(&x);
definiti
@sandeep, i dint get what do you mean by simulate here, as in an example wud
be gud.

I'd say C language is a truly call-by-value language. C++ supports
call-by-reference.
However in C we can "simulate" call-by-reference using pointers and
address-of operator.

As we say in C that we do call by reference but i thk call by
reference is something different like we do through "void pointer" in c
++ but it should be call by address in C is it so?
