C int byte size
Websizeof is a unary operator in the programming languages C and C++.It generates the storage size of an expression or a data type, measured in the number of char-sized units.Consequently, the construct sizeof (char) is guaranteed to be 1.The actual number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the … WebSep 27, 2024 · std::byte is a distinct type that implements the concept of byte as specified in the C++ language definition. Like char and unsigned char, it can be used to access raw memory occupied by other objects ( object representation ), but unlike those types, it is not a character type and is not an arithmetic type.
