Sep 4, 2023 · The Union is a user-defined data type in C language that can contain elements of the different data types just like structure. But unlike structures, all the members in the C union are stored in the same memory location. Due to this, only one member can store data at the given instance.

What is a C union? A structure allows you to define a new data type with multiple related fields. Each field takes up a separate storage location. For example: structpoint {int x; int y; }; Code language:C++(cpp) The point structure has two fields x-coordinate and y-coordinate. Each takes up a separate space in the memory.
