Data Types

Data types in C++ categorize the kind of values a variable can hold, influencing memory usage and allowable operations. C++ offers fundamental types like int for integers, float and double for floating-point numbers, char for single characters, and bool for logical values. Beyond these basics, derived types such as arrays, pointers, and references provide more complex data handling capabilities. Finally, users can define their own types using structures, classes, and unions to create custom data organizations.
