Advantages of Union Union takes less memory space as compared to the structure . Only the largest size data member can be directly accessed while using a union. It is used when you want to use less (same) memory for different data members.

If you want to use same memory location for two or more members, union is the best for that . Unions are similar to the structure. Union variables are created in same manner as structure variables. The keyword “union” is used to define unions in C language.

Read moreIn which applications union can be useful?
The primary use of a union is allowing access to a common location by different data types , for example hardware input/output access, bitfield and word sharing, or type punning. Unions can also provide low-level polymorphism.

Read moreWhat is the use of unions in C?
C unions allow data members which are mutually exclusive to share the same memory . This is quite important when memory is valuable, such as in embedded systems. Unions are mostly used in embedded programming where direct access to the memory is needed.
