Study Notes

What is a Computer Program?

A sequence of instructions that a computer can execute.
Programs are written using programming languages.
A computer program is a finite, deterministic, and effective problem-solving method.
An Algorithm is a method suitable for implementation as a computer program, typically to solve a bunch of problems or to perform a computation.

C++ as a First Language

C++ is a highly regarded programming language.
It provides control over memory management.
C++ is one of the fastest programming languages regarding execution speed.
C++ promotes a structured and disciplined approach to designing programs.

Levels of Programming

High-level: Uses more human-readable code and instructions.
Middle-level: Bridges the gap between high and low-level languages.
Low-level: Closer to the computer's hardware.

Compilers and Linkers

Compilers translate high-level programming language programs into machine language.
Machine language is also referred to as object code.
Linkers combine object code with missing functions to produce an executable program.

Types of Programming

Procedure-Oriented Programming (POP): Based on a list of instructions, each statement tells the computer what to do step by step.
Object-Oriented Programming (OOP): Based on the concept of objects.

IDE and Books

Recommended IDE: Visual Studio 2019
Other IDE Options: Code::Blocks, Dev C++, Xcode, and Netbeans.
Recommended Textbooks:
- Deitel P.J. and Deitel H.M. 2017. C++ How to Program, 10th global edition
- Herbert Schildt. 2003. The Complete Reference C++, 4th edition

First Program – Print on Console

The <iostream> header file is essential for input/output operations in C++.
The std namespace is used to avoid naming conflicts in a large program.
cout is used for printing information to the console.
endl adds a newline character to the output stream.
Every statement ends with a semicolon (;).
C++ programs execute from the main function.
The return 0; statement indicates successful termination of the program.

Variables

Variables are named locations in memory used to store data.
They are essential for storing and manipulating data during program execution.

How Memory Works

Memory in a computer is like a set of drawers, each with a unique address.
Each drawer can hold only one value.
Variables are names for memory addresses, allowing indirect access to the corresponding memory slots.

Variable Declaration

Declaring a variable reserves space in memory for storing data.
The syntax for declaration involves specifying the data type and variable name.
Data type determines the type of data a variable can hold (e.g., integer, floating-point number, character).
Variable name allows access to the memory location associated with the variable.

Variable Declaration Properties

Multiple variables of the same data type can be declared in a single line using commas.
