WebWhat are fixed-width integers? C99 has defined a set of fixed-width integers that are guaranteed to have the same size on any architecture. These can be found in stdint.h header. C++ officially adopted these fixed-width integers as part of C++11. They can be accessed by including the cstdint header, where they are defined inside the std namespace. The C99 standard includes definitions of several new integer types to enhance the portability of programs. The already available basic integer types were deemed insufficient, because their actual sizes are implementation defined and may vary across different systems. The new types are especially useful in embedded environments where hardware usually supports only several types and that support varies between different environments. All new types are defined in
