Introduction to References

A reference is an alias, or an alternative name, for an existing variable. It provides a way to access the value of a variable indirectly through another name. They do not have a memory address of their own. Instead they refer to the memory address of the variable they are referencing.

reference.h

reference.h

copy

              
12

            
int originalVariable = 42;
int& referenceVariable = originalVariable;

Now referenceVariable is an alias for originalVariable. The primary purpose of references is to simplify and make safe, more readable code and avoid unnecessary memory overhead.
