Introduction to C++ Templates
Templates are a mechanism for writing generic code that works with any data type. Unlike traditional functions and classes, which are specific to a particular data type, templates allow you to write code once and use it with different types seamlessly.
How to turn this in a single function?
In this course, you'll learn how to use templates in various scenarios and write concise, scalable code. For example, you'll discover how to create a single function that can replace multiple ones and it is only the tip of the iceberg.
functions.h
12345int add(int a, int b) { return a + b; } float add(float a, float b) { return a + b; } std::string add(std::string a, std::string b) { return a + b; }
template.h
12template<typename T> T add(T a, T b) { return a + b; }
