To address the uncertainty of the default types provided by C and C++, both provide the standard integer types, which are accessible from the stdint.h header file. This header defines the following types:
- int8_t, uint8_t
- int16_t, uint16_t
- int32_t, uint32_t
- int64_t, uint64_t
In addition, stdint.h provides both least and fast versions of the aforementioned types, and a max type and integer pointer type, which is all out-of-scope for this book. The previous types do exactly what you would expect; they define the width of integer types with a specific number of bits. For example, an int8_t is a signed 8 bit integer. No matter what the CPU architecture, operating system, or mode is, these types are always the ...
