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: ```c 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?**
