Structs allow us to group variable of different data types together into a single unit.
-
Individual variables in a struct are called members.
- structname.membername
- A struct within a struct is a nested struct
Structs allow us to group variable of different data types together into a single unit.
Individual variables in a struct are called members.
1 -> To have the possibillity to store multiple (and more important different) variables in one struct in a easy way
2 -> Each individual variable or data type stored in a struct is a member
3 -> For example the struct is called “Employee” and has a member called “Age” so to access the member in the struct is as follows: Employee.Age
4 -> a nested struct is a struct that contains another struct
Structs C++ - Reading Assignment.
We need struct because it allows us to group variables of mixed data types into single unit.
Members in a struct are variables that are part of the struct.
eg.
an Employee is a declaration and his/her age, wage are referred to as the members.
We can access a member inside a struct by using the member selector operator (which is a period).
eg.
john.id
A nested struct is a structure within a structure.
eg.
using a member selector operator twice.
myCompany. MD . wage
Why do we need structs?
Structs are needed to group different variables of mixed data types together into a single unit.
What are members in a struct?
Members are variables in a struct.
How do you access a member inside a struct?
structName.member
What is a nested struct?
A struct within a struct.
1. Why do we need structs?
because we can create an aggregate data type. it looks kinda like an object (correct me if i’m wrong), but a struct is almost like an object but you can specifie what values and parameters can be stored within the struct.
2. What are members in a struct?
these are variables that are in the structure
3. How do you access a member inside a struct?
structname.membername
4. What is a nested struct?
this is a struct you can put inside of another struct but with other members.
A struct (short for structure) allows us to group variables of mixed data types together into a single unit.
These variables that are part of the struct are called members (or fields)
In order to access the individual members, we use the member selection operator (which is a period).
You can nest one struct into another struct, this is a nested struct
Why do we need structs?
= To create more advanced objects consisting of more than 1 variables.
What are members in a struct?
= Members are the variables in a struct.
How do you access a member inside a struct?
= structName.memberName
What is a nested struct?
= A struct inside a struct.
We need structs to group multiple variables of mixed data type together.
Members in a struct are the discreet variables contained within the struct.
To access a member within a struct we use a member selection operator (period).
A nested struct is a struct inside a struct.
We need structs because creating individual variables that are all representative of a similar object, yet are all separate form each other in coding, can get pretty unorganized quickly.
…That’s why we are able to group these related variables together inside of a struct, using “member variables.” We can then assign (initialize) values to these using correct coding (ie struct Employee
{
short id;
int age;
double wage;
};
Employee will{34, 29, 75000.0}
returns …
Will’s ID is: 34
Will’s age is: 29
Will’s wage is: 75000.0
1. Why do we need structs?
Structs come in handy when you want to declare more than one variable for a single user. These variables can be called a lot more efficiently than if you declared them one-by-one.
2. What are members in a struct?
These are the variables within a struct.
3. How do you access a member inside a struct?
struct.member
4. What is a nested struct?
This is a struct that has been defined within another struct. An example of this is: Employee
being defined within the Company
struct.
Will is not a member of struct Employee
Why do we need structs?
It’s useful in the cases where we need more than one variable in order to represent an object.
What are members in a struct?
Members are the variables that are part of the struct.
How do you access a member inside a struct?
The struct dot(.) and then the member
What is a nested struct?
It’s a struct that contain another struct.
1. Why do we need structs?
So that we can aggregate similar properties into a single object and avoid writing extra code. We can pass closely related properties as a single struct object to a function as opposed to passing each variable from the group.
2. What are members in a struct?
The variables/properties defined within a struct are called members.
3. How do you access a member inside a struct?
We use the .
operator after the struct name and type the member we would like to access.
Example:
struct Person{
string name,
int age,
string gender
}
int main() {
Person person;
person.name = "John"
...etc...
}
4. What is a nested struct?
A struct that contains another struct as its member.
