Learn how to create user-defined literals in C++ to improve the expressiveness of your code and handle specific data types with ease.

Here’s an example of a user-defined literal that converts an integer to meters:

// User-defined literal for meters long double operator"" _m(long double x) { return x; // simply returns the value as meters } int main() { auto distance = 10.0_m; // 10 meters std::cout << "Distance: " << distance << " meters" << std::endl; return 0; }
