Moreover, what are the storage classes in C++?Storage class specifiers supported in C++ are auto, register, static, extern and mutable. This is the default storage class we have been using so far. It applies to local variables only and the variable is visible only inside the function in which it is declared and it dies as soon as the function execution is over.One may also ask, how many storage classes are available in C++? five Accordingly, what are different storage classes? Along with the life time of a variable, storage class also determines variable’s storage location (memory or registers), the scope (visibility level) of the variable, and the initial value of the variable. There are four storage classes in C those are automatic, register, static, and external.What is register storage class?The register storage class is used to define local variables that should be stored in a register instead of RAM. This means that the variable has a maximum size equal to the register size (usually one word) and can’t have the unary ‘&’ operator applied to it (as it does not have a memory location).
