call by reference

[jamihuq]

Hello all,
I have a question. Does the concept of call by reference exist in C
like it does in C++? And if so, can someone give me an example.

Thanks
Jami

You use pointers. Caller has to know and provide the appropriate data.

Hi,

It works the same way, i.e. you pass an `int' by value, but there are
no references in C. So you must pass a pointer to an int, in order to
have call by reference.

The concept exists independent of language.

The language support for the concept differs depending on the language.

Since C is mostly a subset of C++, the support present in C (namely,
pointers) is also present in C++, and in addition C++ has a dedicated
reference type.
