WebMar 7, 2024 · Unsigned integer arithmetic is always performed modulo 2n where n is the number of bits in that particular integer. E.g. for unsigned int, adding one to UINT_MAX gives 0 , and subtracting one from 0 gives UINT_MAX . WebIn this tutorial, we will write the C++ Program to find the range of Data Types using Macro constants or without using any macro constants. header file is defined to find the range of fundamental data-types. Unsigned modifiers have minimum value is zero. So, no macro constants are defined for the unsigned minimum value.
