declare a structer in cpp
A structure in C++ can be declared using the struct
keyword. Here is an example of how to declare a structure in C++:
struct Person {
std::string name;
int age;
float height;
};
In this example, we have declared a structure named Person
. The structure contains three members: name
, age
, and height
. Each member is separated by a semicolon (;).
The name
member is of type std::string
, which is a C++ class for handling strings. It represents the name of the person.
The age
member is of type int
, which represents the age of the person.
The height
member is of type float
, which represents the height of the person.
By declaring a structure, we are creating a new data type that can hold multiple values of different types. We can then use this structure to create variables and store data related to a person, such as their name, age, and height.
Structures in C++ are often used to organize related data and create user-defined data types. They provide a way to group together different variables that are logically related to each other.
