Migrating Code from C++98 to C++17: Simplifying and Optimizing

TLDRIn this episode, host Jason Turner continues migrating code from C++98 to modern, clean, and maintainable C++17. He focuses on simplifying and optimizing the code, using string_views and constexpr features. Jason also introduces the concept of Rational Numbers and demonstrates how to simplify them using the Greatest Common Divisor and Least Common Multiple.

Q&A

What are the main challenges of migrating code from C++98 to C++17?

The main challenges include understanding new language features, updating deprecated code, and ensuring compatibility with the new standard.

How does simplification contribute to code optimization?

Simplification reduces code complexity, improves readability, and can lead to performance optimizations.

What are Rational Numbers?

Rational Numbers are numbers that can be expressed as a fraction or ratio of two integers.

How are Rational Numbers simplified using the Greatest Common Divisor and Least Common Multiple?

The Greatest Common Divisor helps in reducing the numerator and denominator to their simplest form, while the Least Common Multiple is used to find a common denominator for operations like addition and subtraction.

Why is fuzz testing important?

Fuzz testing helps identify and fix bugs by generating random or mutated inputs to stress test the program.
