What is similar to union in C?
The following are the similarities between structure and union: Both structure and union are the custom data types that store different types of data together as a single entity. The structure and union members can be objects of any type, such as other structures, unions, or arrays.
Can we use structure inside union in C?
A structure can be nested inside a union and it is called union of structures. It is possible to create a union inside a structure.
What is the structure of union in C?
Union in C is a special data type available in C that allows storing different data types 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 purposes.
Why union is better than structure in C?
In the case of a Structure, there is a specific memory location for every input data member. Thus, it can store multiple values of the various members. In the case of a Union, there is an allocation of only one shared memory for all the input data members. Thus, it stores one value at a time for all of its members.
