Unions in C ++
Unions are a special data type that allows you to store different data types in the same memory location. However, only one member of the union can hold a value at any given time. This makes them quite different from structs, where each member has its own dedicated memory. Key Characteristics of Unions: * Shared Memory: All members of a union share the same memory location. The size of the union is determined by the size of its largest member. * One Active Member at a Time: Only one member of the union can hold a value at any given time. Assigning a value to one member overwrites the value of any other member. * Accessing Members: You access union members using the dot operator (.) or the arrow operator (->) just like with structs. * Initialization: You can initialize a union when you declare it, but only the first member can be initialized directly.
