WebJun 6, 2024 · C and C++ use 32 bit int because otherwise there is no 32 bit type available (char = 8 bit, short = 16 bit or you have no 16 bit type, int must be 32 bit or you have no 32 bit type). Swift on 64 bit devices has Int = 64 bit, but also has Int8, Int16, Int32 and Int64 so the problem that C has is avoided. – gnasher729 Jun 6, 2024 at 18:53 4 WebMar 18, 2024 · Summary. A C++ variable provides us with a named storage capability. C++ variable types: int, double, char, float, string, bool, etc. The contained (or nested) scope is referred to as an inner scope, and the containing scope is the outer scope. A variable of one type can be converted into another.
WebThe syntax to declare a new variable in C++ is straightforward: we simply write the type followed by the variable name (i.e., its identifier). For example: 1 2 int a; float mynumber; These are two valid declarations of variables. The first one declares a variable of type int with the identifier a. WebC++ References •Reference == a variable that refers to a particular memory address •Reference declaration: int i = 4; int &i_ref = i; •A reference MUST be initialized •Once initialized, the memory address referred to by a reference variable cant change •i.e. i_ref above must always refer to the address of i.
