In Java, type casting is a method or process that converts a data type into another data type in both ways manually and automatically. when compiler converts implicitly, there may be a data loss. Important note: Explicit typecasting can also result in data loss. Python | Unpack whole list into variables 3. The most general cast supported by most of the C++ compilers is as follows (type) expression Where type is the desired data type. However, the value stored in a can be cast to other types when it is used in expressions. Typecasting is also called an explicit type conversion. Appreciate your help to do this type casting. The process of converting a lower type to higher is known as integer promotion. Is the C compiler gone mad?
