Chapter 1: Introduction to Templates in C++

C++ templates are intimidating for any beginner or intermediate level programmer as it is syntactically a bit cryptic and complex. Also, there are intricacies in how to use the powerful features of the language. A standard C++ book does not always go into the feature’s details instead of just touching upon the subject, which is not sufficiently explanatory for the first-time learners. Sometimes the examples are too complicated, or the explanations are too vague to understand. Often, there are not many different sample codes to practice enough to have a good grip on the subject. In other cases, the available books go so deep into the nitty-gritty of the language that the reader feels a bit lost in the sea of information. In either way, the subject seems daunting for the newbies or intermediate-level programmers. However, if we explain it systematically with simple examples and easy-to-understand explanations, the C++ template could be a powerful tool for programmers. Proper use of templates can lead to clean, elegant, and efficient code on many occasions. The reader should be a beginner or intermediate-level programmer who has a basic understanding of C++ programming. They do not need to have detailed, in-depth knowledge or vast experience on the subject but should be familiar with the C++ programming paradigm’s basic concepts and be looking to take it to the next level.
