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 … WebOnly rule that the standard says is that long is at least 32 bits. So, to have control of the number of bits, use #include (or in C, stdint.h ), and use the types for example uint16_t or uint32_t - then you KNOW that it will hold a given number of bits. On a processor that has 36-bit "wordsize", the type uint32_t for example, will not ...

WebFeb 25, 2010 · In other words, a specific C or C++ implementation for a 64-bit hardware/OS platform is absolutely free to implement int as a 71-bit 1's-complement signed integral type that occupies 128 bits of memory, using the other 57 bits as padding bits that are always required to store the birthdate of the compiler author's girlfriend. The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type:
