Details slides about structs. In C++, a struct is a user-defined data type that groups together variables of different data types under a single name.
Here's an example of a struct definition:
c
struct Person {
std::string name;
int age;
float height;
};
In this example, we've defined a struct called Person that contains three member variables: a string name, an integer age, and a float height.
We can create instances of this struct and access its members like this:
c
Person john;
john.name = "John Doe";
john.age = 30;
john.height = 6.2;
std::cout << john.name << " is " << john.age << " years old and is " << john.height << " feet tall." << std::endl;
This would output:
python
John Doe is 30 years old and is 6.2 feet tall.
Structs can be useful for organizing related data together, and can be passed as arguments to functions or returned from functions just like any other data type. Additionally, C++ structs can have member functions, just like classes, but with some syntactical differences.
