Solution
The purpose of the union keyword in C is to declare a new data type. A union is a special data type available in C that allows to store different types of data in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-use.
