What is call by reference in functions?..

Answer / hrpynux@gmail.com

The call by reference method of passing arguments to a function copies the address of an argument into the formal parameter. ... It means the changes made to the parameter affect the passed argument. To pass a value by reference, argument pointers are passed to the functions just like any other value.
