Is there no reference variables in c as in c++?

Question

int swap(int &,int &);why is this invalid in c?is call by reference only through pointers in c and not through reference variables as in c++?

Answer 1

We don't have reference variables or "aliases" in C. When we say "pass by reference" in C, we refer to the act of passing the pointer to a variable, to a function.

Answer 2

c has no reference variable rather than you can use pointer to work call by reference..
int swap(int *,int*)
