The major difference between call by value and call by reference is that in call by value a copy of actual arguments is passed to respective formal arguments. While, in call by reference the location address of actual arguments is passed to formal arguments, hence any change made to formal arguments will also reflect in actual arguments. In C, the calling and called functions do not share any memory -- they have their own copy and the called function cannot directly alter a variable in the calling function; it can only alter its private, temporary copy. The call by value scheme is an asset, however, not a liability. It usually leads to more compact programs with fewer extraneous variables, because parameters can be treated as conveniently initialized local variables in the called routine.

Passing Arrays to Methods in Java

This value depends on the method return type like int method always return an integer value. The last control statement is return.

When an argument is passed by value the default in C , a copy of its value is made and passed to the called method. This prevents the accidental side effects that so greatly hinder the development of correct and reliable software systems. To pass an object by reference into a method, simply provide as an argument in the method call the variable that refers to the object.

If you think that I can use more precise words at any part of the tutorial, or an example can be added or simply you do not agree with me; drop me a comment.

In this tutorial, you will learn to create user-defined functions in C programming with the help of an example. C allows you to define functions according to your need.
