A union is a special data type available in C that allows to store 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-purpose.
Read moreWhat is the advantage of union in C?
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.
Read moreWhat is the main use of union?
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 union in C advantages and disadvantages?
The basic advantage is that union will use the memory space of the datatype which has the highest memory …. hence memory consumption will be less…But when u use structure the total memory will be the sum of the memory of all datatypes.. ie. (higher memory allocation)Disadvantage is that…..
