WebC99 has defined a set of fixed-width integers that are guaranteed to have the same size on any architecture. These can be found in stdint.h header. C++ officially adopted these fixed-width integers as part of C++11. They can be accessed by including the cstdint header, where they are defined inside the std namespace. WebThere are 5 basic numerical types representing booleans (bool), integers (int), unsigned integers (uint) floating point (float) and complex. Those with numbers in their name indicate the bitsize of the type (i.e. how many bits are needed to represent a single value in memory).

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.
