Study Notes
Overview of Computers and Programming Languages
- Computers consist of hardware and software components that work together to process data.
- Hardware includes physical parts like the CPU, memory, and input/output devices.
- Software encompasses programs and applications that instruct the hardware on how to perform tasks.
Evolution of Programming Languages
- Programming languages are classified into high-level and low-level languages.
- High-level languages provide abstraction from machine language, aiding in easier program development.
- Notable high-level languages include:
- Basic
- FORTRAN
- COBOL
- Pascal
- C
- C++
- C#
- Java
- Low-level languages are close to machine code and include assembly language.
Compilers and Language Translation
- A compiler is a crucial tool that translates high-level language code into machine language that the computer can execute.
- This translation process allows developers to write code in a user-friendly format while optimizing it for machine execution.
Processing a C++ Program
- Basic structure of a C++ program includes:
- Preprocessor directives (e.g.,
#include
) which allow for the inclusion of libraries. - The
main()
function serves as the entry point of the program. -
cout
is used for outputting text to the console.
- Preprocessor directives (e.g.,
