type_traits

Type traits are tools used in programming to analyze and manipulate data types at compile time. They help determine properties of types—such as whether a type is an integer, a floating-point number, or a class—without executing the program. This allows developers to write more flexible and optimized code that adapts based on data types, ensuring correctness and efficiency. In C++, the `` library provides these tools, enabling more generic and type-safe programming by providing compile-time information about types.
