Are there references in C?
When reading posts at programming sites such as this one, I frequently encounter people saying things like:
"There is no pass-by-reference in C, everything is passed by value."
People claiming such tend to be of the C++ programmer variety and are used to the C++ syntax distinction between pointers int* and references int&, which doesn't exist in C. And the argument usually goes:
void func (int* x);
...
int* p = &data;
func(p); // here the pointer p is passed by value
And sure, there is no denying that the pointer in this example is passed by value.
Questions: Are there references in C? Is it possible to pass variables by reference in C?
