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.

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.

Advantages of union When you use union, only the last variable can be directly accessed . Union is used when you have to use the same memory location for two or more data members. It enables you to hold data of only one data member. Its allocated space is equal to maximum size of the data member.8 Şub 2022
