Study Notes

Introduction to Programming

Programming involves creating a set of instructions for computers to execute a specific task.
A programmer is an individual proficient in writing computer programs.
Programming is crucial for developing software and applications.

Levels of Programming Languages

Machine Language:
- Utilizes binary code (0s and 1s) and is directly executed by computers.
- Rarely written or read by programmers.
Assembly Language:
- Utilizes mnemonic commands (e.g., mov, add, sub) and corresponds directly to machine language instructions.
- Requires an assembler to convert assembly code to machine code.
High-Level Language (HLL):
- Features English-like syntax, making it easier for humans to read and write.
- Requires a compiler to translate HLL into machine language.

Compilers and Assemblers

Compiler:
- Translates the entire source code written in HLL into machine language in a single operation.
Assembler:
- Converts assembly language into machine code.
Interpreter:
- Translates and executes HLL statements one at a time, rather than compiling the whole program first.

C# Programming Language

Developed as an object-oriented and component-oriented language, integrated into Visual Studio.NET.
Modeled after C++, without the use of pointers or multiple inheritance.
Simplifies programming by eliminating the need for object destructors, forward declarations, or #include files.

Writing a C# Program

Program output is produced using methods like WriteLine(), which prints a specified string to the console.
The Console class represents the collection of console objects, and Out is the object that interacts with the screen.

Namespaces in C#

System is a namespace used to organize classes and group similar functionalities for easier management.

Compiling and Executing C# Programs

Source code must be compiled into intermediate language (IL) using the command csc followed by the filename.
Successful compilation results in executable statements, while errors can occur either due to operating system or program language errors.
Common pitfalls include misspelling commands, failing to include the correct file extension, and operating outside the correct directory.

Error Handling

An operating system error can indicate various issues such as typos or misconfiguration.
Syntax errors arise from typing mistakes within the code, leading to unsuccessful program execution.
