Part 6 - Reference variables and keywords in c++ | byprofessionalengineers
Reference variables are a type of variable in C++ that act as an alias for another variable. They are declared using the '&' symbol after the data type, followed by the name of the reference variable. When you assign a value to a reference variable, it actually assigns the value to the variable that it refers to. This can be useful for creating aliases for complex objects, or for passing arguments to functions by reference instead of by value.
Keywords in C++ are reserved words that have a special meaning in the language. They cannot be used as variable names or other identifiers, and are used to define the structure and behavior of the program. Examples of C++ keywords include 'if', 'else', 'while', 'for', 'switch', 'case', 'return', and 'class'.
