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.cpp
pair.cpp
vector.cpp
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.
Swipe to start coding
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.
