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
Chapter Goals
- Learn the architecture of computers
- Learn about machine and higher-level programming languages
- Gain familiarity with a compiler
- Compile and run a C++ program
- Identify compile-time and run-time errors
- Describe algorithms using pseudocode
- Understand the activity of programming
What Is Programming?
- Computers carry out tasks by executing programs
- Programs are sequences of steps that tell a computer how to complete a task
- Hardware refers to the physical computer and its devices
- Software refers to the programs the computer executes
- Programming is the act of designing and implementing computer programs
The Edit-Compile-Run Loop
- This process reflects how programmers typically work
Becoming Familiar with Your Programming Environment
- You need to understand your computer's file system
- C++ program files commonly use the extension .cpp
- Create folders to organize your files
- It is crucial to back up your work regularly
Analyzing Your First Program
- The classic first program is Hello World!
- It displays the text "Hello World!" on the screen
