WebApr 11, 2024 · What is Type Conversion in C++ Type conversion in C++ refers to the process of converting a variable from one data type to another. To perform operations on variables of different data types we need to convert the variables to the same data type using implicit or explicit type conversion methods. WebSetting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 …
