Constants in C const vs define

Image
Learn how to use constants in C programming on Debian 12. This tutorial covers both const keyword and #define preprocessor with practical examples. Understanding Constants in C Programming Constants in C are fixed values that cannot be altered during program execution. Using constants makes your code more readable and maintainable. In C, there are two main ways to define constants: using the const keyword and the #define preprocessor directive. The const Keyword The const keyword creates a read-only variable. Once initialized, its value cannot be changed. The syntax is: const type name = value; For example: const float PI = 3.14159; const int MAX_USERS = 100; Key characteristics: Has data type and scope rules like normal variables Allocated storage in memory Can be used for array sizes in C99 and later The #define Preprocessor #define creates macro constants th...

Dynamic Attribute Access with getattr and setattr

Image
Learn how to use Python's getattr and setattr for dynamic attribute access and modification in your classes. Dynamic Attribute Access in Python with getattr and setattr In Python, attributes of an object are typically accessed directly using dot notation, like obj.attr . However, there are situations where you may need to access or modify attributes dynamically at runtime. For these cases, Python provides the built-in functions getattr and setattr , which allow attribute access and modification using string names. Why Use getattr and setattr? Dynamic attribute access is powerful in scenarios such as: Working with objects whose attributes are determined at runtime. Building frameworks or libraries that need to inspect or modify user-defined classes. Implementing generic code that can handle different types of objects without hardcoding attribute names. Using getattr getattr(object...

Data Types in C int char float double etc

Image
Learn about data types in C programming on Debian 12 using Vim. This tutorial explains int, char, float, double, and more with practical examples. Understanding Data Types in C Programming Data types in C define the type of data a variable can hold. Choosing the correct data type is crucial because it determines the amount of memory allocated and the kind of operations that can be performed on the data. What Are Data Types? In C, data types are declarations for variables that determine the characteristics of the data, such as the size and range of values that can be stored. The primary data types in C include: int : Stores integers like 10, -25. char : Stores single characters like 'A', 'z'. float : Stores decimal numbers with single precision like 3.14. double : Stores decimal numbers with double precision for higher accuracy. Declaring Variables with Data Types ...

Viewing and Cleaning Stashes

Image
Learn how to view and clean up your stashes in Git to keep your workspace organized. Viewing and Cleaning Stashes in Git When using git stash to save your work in progress, it is easy to accumulate multiple stashes over time. Managing them efficiently is crucial to avoid confusion and keep your workspace tidy. This tutorial explains how to view all your stashes and clean up unneeded ones in Git. Listing All Stashes To see all stashed changes, use the following command: git stash list This displays a list of saved stashes along with their identifiers, making it easy to know what each stash contains. Inspecting a Specific Stash To look inside a specific stash without applying it, run: git stash show -p stash@0 Replace stash@0 with the identifier of the stash you want to inspect. Dropping a Single Stash When a stash is no longer needed, you can remove it using: git stash drop sta...
