NettetThe basic (fundamental) data types provided by c++ are integral, floating point and void data type. Among these data types, the integral and floating-point data types can be preceded by several type modifiers. These modifiers (also known as type qualifiers) are the keywords that alter either size or range or both of the data types. Nettet10. feb. 2024 · C++ Utilities library Type support Types The implementation may define typedef names intN_t, int_fastN_t, int_leastN_t, uintN_t, uint_fastN_t, and uint_leastN_t … NettetFixed-width integers are integral types with a fixed number of bits. The C++ standard only specifies a minimum byte count for types such as short, int and long. Fixed-width integers guarantee a specific size, but their use can have an impact on portability, since they are not supported by all platforms.
