bookIntroduction to Class templates

In addition to function templates, there are also class templates. They share many of the same concepts, so what you have already learned applies for this as well. Look at the simple example of class template:

cpp

main

copy

              
123456789101112131415

            
#include <iostream>

// Creating a template using `template` keyword
template <typename T>
class Box {
private:
    T value; // Stores the value of type `T`
public:
    Box(T value) : value(value) {} // Constructor initializes the `value`
};

int main()
{
    Box<int> intBox(123); // Creating a Box object for an integer type
}

Note

Try to pass different types to the class.

Class templates are often used as containers for data because they allow you to choose any type for storage. This flexibility enables the creation of generic data structures.
