In C++ interview questions, one common topic is the different data types available. C++ data types are broadly classified into three categories:
• Primitive: Primitive data types include fundamental types like int, float, char, and bool.
• Derived: Derived data types are more complex and include arrays, pointers, and functions.
• User-Defined: User-defined data types, such as classes, structures, and unions, allow programmers to define custom data types.
