Programming in C++ | Pass By Value | ~xRay Pixy


PROGRAM TO SHOW HOW PASS BY VALUE WORKS? C++ program to Swap variable values using the 3rd variable.
C++ is the mother of Object-Oriented Programming.

Arguments Passing is a Process of transferring data between the calling function and the called function. In C++,  there are three ways by which arguments can be passed.
  1. Pass By Value
  2. Pass By Address or Pass By Pointer
  3. Pass By Reference
Most of the programming languages like C use only the first two modules (i.e., Passing by Value and Address) whereas C++ supports all the three methods of passing arguments.

Pass By Value: It is a default method for argument passing. When an argument is passed by value than a copy of the argument is made and passed to the newly created formal arguments in the called function. The formal arguments contain a copy of actual arguments that are stored in the separate memory location.
