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
coutstatement is used for outputting data to the console.
