However, you can expect an int to be at least 16 bits in size. This means that it can store values from -32,768 to 32,767, or more depending on hardware. Like all of these other data types, there is an unsigned variant that can be used.

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.
Nettet2. aug. 2024 · The int and unsigned int types have a size of four bytes. However, portable code should not depend on the size of int because the language standard allows this to be implementation-specific. C/C++ in Visual Studio also supports sized integer types.

The idea of bit-field is to use memory efficiently when we know that the value of a field or group of fields will never exceed a limit or is within a small range. Bit fields are used when the storage of our program is limited. Need of bit fields in C programming language: phenol hazardsThe 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.
