since there are times that we would need to store datas of different types, for instance adding a profile to database which contains of different data types such as digits and strings therefore we need Structs since it allows us to do so.
-
The different variables that are in a struct are called members.
-
we use member selection operator
-
structs can contain other structs, thats what we call nested struct.

Because build-in data types are too limiting and often we need to represent more complexed objects with multiple variables, struct is providing us a way to do that properly.
-
Variables declared in a struct are called members or fields/properties. They usually represent particular traits of the struct (the name or age of a person for example).

structIdentifier.memberIdentifier

This is a struct which is a member of another struct.

We can use structs to represent objects by grouping variables of mixed types into a single struct data type.

Members (or fields) within a struct are the variables it contains.

Members can be accessed with the member selection operator ’ . ’ .

A nested struct is a struct within a struct. It is contained as a member of another struct, and it’s members can be accessed by using the member selection operator ‘.’ twice. Nested structs can also be initialized with a nested initializer list.

- Structs are needed to aggregate multiple variables of different data types into a single unit. They are good solution to represent a real-life object and manipulate it in a comfortable way.
- Members are component variables of a struct. They are also known as fields.
- We can access a field through the member selection operator which is a fancy name for a period. Example
structName.structsMember. - A nested struct is simply a member of another struct.

- Its much more logical/efficient to use structs. As it allows us to easily store a group of variables and mixed data types together into a single unit. Instead of individually declaring independent variables each time we want to add a new variable.
- Variables that are part of structs
- By using the member selection operator (which is a period). For example, bob.age

We need structs in order to create structures that can hold variable information in a scaleable manner.
The members of a struct is the individual variables that are held in the struct.
By calling the member in the following manner: nameofstruct.nameofmember.
For instance: Person.name.
Its a struct within a struct. It is used when information inside the mother struct has more information paired with it.

It allows us to group variables of many mixed data types together in single unit. For example a struct could be created to hold variables that represent an object, such as a Car, with characteristics such as doors, wheels, miles, number plate, fuel, transmission and colour. -

These are the variables in the struct, they can also be known as fields. In the car example above, the members are doors, wheels, miles, number plate, fuel, transmission and colour. -

1 With a struct yo can give a function several arguments at the same time, as you do not have to handle every variable separatly.
2 The members are the parts of the struct. A struct is like an array, but each element can be a different type. The members correspond to the elements.
3 struct.member
4 You may define a struct as a list of variables (members). But a struct is also a variable so if you have a struct as on of the variables in your struct, you have a nested struct.
