Structs C++ - Reading Assignments

C++ Programming
#41

Structs allow us to group multiple fields/members (variables which may or may not be of the same type) into a single unit (the struct).

Members are accessed using a dot and the member name, much like JavaScript objects: myStruct.myMember

A nested struct is a struct within a struct.

#42
  1. Structs are need for storing data elements together inside a single container usually for storing logically related data.
  2. The data elements inside the struct
  3. Dot operator : <struct name>.<member name> e.g. Employee.age;
  4. A struct that has a member which is itself of a struct type.
#43

  1. structs are to organise variables more easily

  2. members are the different variables associated with a struct

  3. to access member object.variable

  4. A nested struct is when a struct is a member of another struct

#44

Why do we need structs?
Grouping variables to better represent real world objects.
What are members in a struct?
the variables inside the struct
How do you access a member inside a struct?
call to the struct referencing the var (i.e Person.age)
What is a nested struct?
A struct that uses a struct as one of its vars has a nested struct.

#45
  1. A struct allows us to group variables of mixed data types into a single object. It is the simplest form of the so-called aggregate data types.
  2. The members (or, also called fields) of a struct are the variables within that struct.
  3. Members of a struct are accessed with the member selection operator, which is simply a dot, e.g.: my_struct.my_field
  4. We speak of a nested struct if a struct contains another struct (which in turn, could possibly again contain another struct etc.).
#46

1. Why do we need structs?
We need Structs when is necessary represent a object that has many properties.

2. What are members in a struct?
They’re the variables inside the struct.

3. How do you access a member inside a struct?
With the following expression: <struct_name>.<member_name>, e.g.: joe.age.

4. What is a nested struct?
It’s a struct that contain another struct as a member.

#47
  1. We need structs to be able to group a set of variables that describe one object.
  2. A member variable that belongs in a struct.
  3. First, we define a variable of your struct type, then to access a member you write: yourVariable.member. The period represents the member selection operator.
  4. A nested struct is when you declare a struct as a variable of another struct.
#48

1. Why do we need structs?

A struct (which is short for structure) is needed because it enables us to group variables of different data types into a single unit. Otherwise, it becomes cumbersome to write out independent variables of different data types at once.

2. What are members in a struct?

A member in a struct is in simple terms the variables inside the struct.

3. How do you access a member inside a struct?

To access a member inside a struct, a programmer must use the member selection operator. The member selection operator is simply the struct followed by a period and the name of the member. As an example of this is as follows:

Animal fish
fish.weight = 7;
fish.length = 4;
fish.name = tilapia

4. What is a nested struct?

A nested struct is a simply a struct placed inside another struct.

#49

Why do we need structs?
Structs are custom data type that we use when with single regular variables is not enough to describe our object. So , is a data type that contains several variables in it.

What are members in a struct?
The members in a struct are all the variables we use in the struct to describe our object.

How do you access a member inside a struct?
We access each member in a struct using the dot (.) notation. ex. myStruct.myMember

What is a nested struct?
A nested struct is when a struct has a member that is an other struct.

#50

1. Why do we need structs?
A struct (short for structure) allows us to group variables of mixed data types together into a single unit.
2. What are members in a struct?
These variables that are part of the struct are called members (or fields).
3. How do you access a member inside a struct?
In order to access the individual members, we use the member selection operator (which is a period).
4. What is a nested struct?
Structs can contain other structs. This is called a nested struct.

#51
  1. To group a lot of information about one specific object to one data structure and have a good template to include others
  2. Members are the names of variables initialized inside that struct - the characteristics of a specific object
  3. By using a name of the struct, together with a dot operator, and a name of a member
  4. It is a struct, that is made of other structs, making one struct more general than the other one

  1. We need structs to logically group objects together, this can reduce the amount of parameters we have to define for our functions, and is the only way to get a function to be able to return multiple values.

  2. Members of struct are the objects in its collection.

  3. You access members of a struct through the member selection operator, also known as dot notation.

        cout << someStruct.someMember << endl;
  1. Structs can be members of other structs, this is referred to as a nested struct.
#53
  1. Struct is a data type that allows us to store multiple variables of different data types in one struct. (object in javascript)
  2. Members are variables contained in struct. (Properties in javascript)
  3. Struct members are accessed with . (dot) operator.
  4. Nested struct is a struct as a member of another struct.

1. Why do we need structs?
A struct (short for structure) allows us to group variables of mixed data types together into a single unit.’
2. What are members in a struct?
variables that are part of the struct are called members (or fields)
3. How do you access a member inside a struct?
In order to access the individual members, we use the member selection operator (which is a period)
eg
Employee jill; // create an Employee struct for jill
jill.id = 11; // assign a value to member id
jill.age = 22; // assign a value to member age
jill.wages = 20.00; // assign a value to member wage
4. What is a nested struct?
Structs can contain other structs.
eg
struct Album
{
short album_id;
string released;
double RRP_price;
};

struct Band
{
short band_id;
string name;
};

#55

Why do we need structs?
To handle, in an easy way, all the information (data types) about a particular object that
we are working on.

What are members in a struct?
Are the different data types variables that are aggregated on the struct.

How do you access a member inside a struct?
With a dot after the name of the structure, like…

NameOfStruct.member

What is a nested struct?
It is a struct that contains another struct.

#56

  1. In order to group variables together to one variable a.k.a “Struct”(Structure)

  2. The variables in a struct is called members.

  3. First you have to declare a variable to the struct you made.
    In order to access a memer in the struct you have to write the variablename.variableinsidestruct.

Example:
Struct Test {
int testvariable;
};

Test iTest;
iTest.testvariable = 0; // This is where we access the member “testvariable”

  1. A nested struct is a struct within a struct. The struct inside the other struct is a member of that struct.

  • Why do we need structs?
    There are many instances in programming where we need more than one variable in order to represent an object. 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).

  • How do you access a member inside a struct?

  • What is a nested struct?
    A nested struct is a struct that can contain other structs. For example:

struct Employee
{
    short id;
    int age;
    double wage;
};
 
struct Company
{
    Employee CEO; // Employee is a struct within the Company struct
    int numberOfEmployees;
};
 
Company myCompany;

They are variables, which are part of the struct.

By using the member selection operator (a period).
