Differbetween
Structure is a data type that stores different data types in the same memory location; the total memory size of the structure is the summation of memory sizes of all its members. ... Meanwhile, Enum is a data type that store integral constants. Thus, this is the main difference between structure union and enum in C.

Structure Vs. Union
| Structure | Union |
|---|---|
| The total size of the structure is the sum of the size of every data member. | The total size of the union is the size of the largest data member. |
| It is mainly used for storing various data types. | It is mainly used for storing one of the many data types that are available. |
What is difference between structure and union in C?
A structure is a user-defined data type available in C that allows to combining data items of different kinds. Structures are used to represent a record. A union is a special data type available in C that allows storing different data types in the same memory location.
What is structure and union in C?
Structure is the container defined in C to store data variables of different type and also supports for the user defined variables storage. ... While in case Union memory is allocated only to one member having largest size among all other input variables and the same location is being get shared among all of these.

Which is better structure or union?
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.
What is the important difference between structure & Union?
The structure and union both are the container data types that can hold data of any “type”. The one major difference that distinguishes structure and union is that the structure has a separate memory location for each of its members whereas, the members of a union share the same memory location.
What is the advantage of union in C?
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.
Why Union is used in C?
C unions are used to save memory. To better understand an union, think of it as a chunk of memory that is used to store variables of different types. When we want to assign a new value to a field, then the existing data is replaced with new data.
What is the advantage of structure in C?
C Structures. Structure is a user-defined datatype in C language which allows us to combine data of different types together. Structure helps to construct a complex data type which is more meaningful. It is somewhat similar to an Array, but an array holds data of similar type only.
Can we declare union inside structure?
Anonymous unions/structures are also known as unnamed unions/structures as they don't have names. Since there is no names, direct objects(or variables) of them are not created and we use them in nested structure or unions. Definition is just like that of a normal union just without a name or tag.
Where is structure and union used?
You use a union when your "thing" can be one of many different things but only one at a time. You use a structure when your "thing" should be a group of other things. In this example, w and g will overlap in memory.
What are functions C?
A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. ... A function declaration tells the compiler about a function's name, return type, and parameters.
