WebAug 9, 2024 · std::int8_t and std::uint8_t likely behave like chars instead of integers Due to an oversight in the C++ specification, most compilers define and treat std::int8_t and std::uint8_t (and the corresponding fast and least fixed-width types) identically to types signed char and unsigned char respectively. WebFeb 23, 2024 · INT_MAX is a macro that specifies that an integer variable cannot store any value beyond this limit. INT_MIN specifies that an integer variable cannot store any value below this limit. Values of INT_MAX and INT_MIN may vary from compiler to compiler. Following are typical values in a compiler where integers are stored using 32 bits.
