Understanding Reference in C++

C++, as a programming language, provides us with a variety of concepts to deal with static as well as dynamic allocation of data through data variables.

Reference enables the programmer to provide a particular variable with an alternative name to it. Thus, a reference can be considered as an alias name to the existing variable.

Reference thus behaves as a label to the variable pointing to the memory location of the stored value in the existing variable.

Let us now focus on the structure of C++ Reference in the upcoming section.

Syntax of C++ reference

Have a look at the below syntax!

int variable = value;

int & reference-variable = variable;

As we can see in the above command, that, we use the ampersand ‘&’ symbol to refer a new variable name to the existing variable.

Thus, the reference variable would point to the same memory location as that of the original variable.

Now, will implement the concept of reference through the examples in the below section.
