The myHash call in the switch on the argument stringType may or may not be a compile time constant, depending on the context the function is called (in a constant expression or not.) … WebC99 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. honeywell n95 flatfold disposable
