Hello,
1) C++ introduces a new kind of variable known as a reference variable.
2) Reference Variable provides an alternative name for a previously defined variable.
3) When a variable declared as a reference, it becomes an alternative name for an actual variable.
4) A variable declared as a reference by putting ‘&’ symbol in the declaration.
Syntax:
[data_type] & [reference_variable]=[regular_variable];
5) A Reference Variable also used in function parameter, this is known as call by reference.
