Bjarne Stroustrup: Why I Created C++ | Big Think

TL;DR

Evolution from low-level code to high-level abstraction in C++ for efficient and stable infrastructure programming.

Transcript

In the really old days, people had to write their code directly to work on the hardware. They wrote load and store instructions to get stuff in and out of memory and they played about with bits and bytes and stuff. You could do pretty good work with that, but it was very specialized. Then they figured out that you could build languages fit for huma... Read More

Questions & Answers

Q: What was the significance of languages like FORTRAN and COBALT before the creation of SIMULA?

FORTRAN and COBALT were designed for specific fields like engineering and business, but were limited in their universal human fit compared to SIMULA's later development.

Q: How did SIMULA introduce the concept of classes and relationships between them in programming?

SIMULA introduced classes as representations of real-world concepts in programming, enabling hierarchical relationships between classes, pioneering object-oriented programming.

Q: What motivated Bjarne Stroustrup to create C++ and what sets it apart from other languages?

Stroustrup aimed to combine SIMULA's class ideas with C's efficiency, resulting in C++ being able to offer high-level abstractions while running as fast as C code, making it ideal for infrastructure programming.

Q: Why is stability crucial in infrastructure programming, and how does C++ address this?

Stability is essential for long-lasting infrastructure, and C++ provides this by being reliable over decades on various hardware platforms, ensuring minimal code rewriting costs.

Summary & Key Takeaways

• In the past, programmers had to write low-level code directly for hardware, leading to specialized work.

• Languages like FORTRAN and COBALT were developed for specific areas before the creation of SIMULA for universal human fit.

• C++ combines SIMULA's class concepts with C's efficiency, making it widely used for high-level abstractions and stable infrastructure.
