In C++ (C Plus Plus), when you call by reference, you are directly accessing the data of the referenced object.

When you pass an object to a function by reference, any and all alterations to the object made within the function carry through to the actual object.

What else can I help you with?

What is calling by reference how it is different from call by value in c program?

Calling a function by value means the variable will be copied. That means that, any changes you make to the variable will be applied to the copy, and not the real one. If you pass by reference, the actual intended variable is modified.

Call by Value:- In this method a copy of the variables is created and is updated time to time but not the actual memory location is updated.so when we make a call to the function we get old valuesCall by Reference:- In this method we access the variable by the reference of the memory location,so when we make call to the variable we get the updated values.


When passing an argument by reference the module can modify the argument in the calling part of the program?

Yes, when passing an argument by reference, changes to the argument made within the module will directly affect the original variable in the calling part of the program. This is because the reference to the original variable's memory address is passed to the module, allowing it to modify the variable directly.


What is a reference variable in c plus plus?

A reference variable in C++ is a formal parameter of a function call that automatically dereferences itself, as if it were a pointer, into a reference to the original value in the calling routine. You declare the reference type in the function declaration and prototype, but the compiler automatically adds the reference (&) operator on call, and the dereference (*) operator on use.
