Study Notes

Programming Language Overview

A programming language is a standardized method for conveying instructions to a computer.
Examples of programming languages include C++, C, and Java.

Categories of Programming Languages

High-Level Programming Languages:
- Syntax is human-readable and resembles natural language, making coding more intuitive.
Low-Level Assembly Language:
- Code is written closely resembling machine code, offering less abstraction from hardware.

Introduction to C++

C++ is a general-purpose programming language created in the early 1980s by Bjarne Stroustrup at Bell Labs.
The primary goal of C++ is to outline specific operations that a computer can carry out.
It allows programming of various tasks primarily focused on manipulating numbers and text.

Getting Started with C++

To develop programs in C++, the following software must be installed:
- Text Editor: Used to write the program code. Examples include Notepad and CodeBlocks.
- C++ Compiler: Translates the written source code into executable format.

Sample C++ Code Components

The header section includes necessary components for handling input and output operations.
The statement using namespace std; directs the compiler to utilize the standard namespace, which organizes code logically.
The int main() function signifies the starting point of program execution.
The cout statement is used for outputting data to the console.
