Template Classes and STL

A template class in C++ isn't restricted to just the class keyword; it also includes templates created with class-like keywords such as struct and union. For instance, many templates in the STL (Standard Template Library) utilize these keywords.

The STL, an essential part of C++ templates, is a comprehensive library of template classes in the C++ Standard Library. It provides efficient, well-tested solutions for common data structures and algorithms, allowing developers to focus more on application logic rather than recreating core functionalities. Some commonly used STL template classes include:

array

pair

vector


              123456
            
// The `std::array` template in C++ (introduced in C++11)
// Is a fixed-size array that encapsulates C-style arrays
// Provides additional functionality
template<class T, std::size_t N> 
struct array;
// Inside <array> header

There's no need to reinvent the wheel. It's much more efficient to use existing, well-tested solutions. Let's practice using template classes from the STL.

Task

Swipe to show code editor

Finish the Initialization of std::pair, std::array, and std::vector

Include all necessary headers.
Based on the parameters passed in the parameter list or initialization list, complete the initialization of the template classes.
