A union is a data type that allows two or more variables of different data types to share the same memory location. This is useful when you have multiple variables that need to be stored in a compact space in memory, but only one variable needs to be accessed at a time. Arrays, classes, and structures also reserve memory for multiple variables, but they do not allow for different data types to share the same memory location as a union does. A union allows for two or more variables of different data types to share the same memory space. This can be useful for conserving memory and optimizing program performance. Arrays, classes, and structures also reserve memory space for multiple variables, but they do not necessarily allow for different data types to coexist in the same memory space.
