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
#includefiles.
Writing a C# Program
- Program output is produced using methods like
WriteLine(), which prints a specified string to the console. - The
Consoleclass represents the collection of console objects, andOutis the object that interacts with the screen.
Namespaces in C#
Systemis 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
cscfollowed 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.
