Study Notes
Machine Code and Programming Languages
- Computer programs are stored as machine instructions
- Machine instructions depend on the processor type
- Instructions are encoded as numbers, allowing for storage in memory
- Encoding differs depending on the processor manufacturer
High-Level Languages and the Compiler
- High-level languages like C++ are hardware independent
- The compiler translates higher-level code into machine instructions for a specific processor
- Machine instructions generated by the compiler differ, but programmers don't need to worry about the differences
The Evolution of C++
- C++ was developed in 1985 by Bjarne Stroustrup of AT&T
- C++ adds features from the Simula object-oriented language to the C programming language
