Linux OS: Naming files and directories

 Naming files and directories in Linux follows specific guidelines to ensure organization and avoid functionality issues. Here's a summary:

General Rules:

  • Case-sensitive: Names are distinguished by case. "myfile" and "MyFile" are considered different files.
  • Start character: Avoid starting names with a hyphen (-) or period (.). These can have special meanings in the command line.
  • Special characters: While technically allowed, using characters like spaces, &, $, etc., can cause problems with certain commands or scripts. Stick to alphanumeric characters, periods (.), and hyphens (-) for better compatibility.
  • Hidden files: Files starting with a dot (.) are hidden by default. Use ls -a to view them.

Recommended practices:

  • Lowercase: Use lowercase letters for better consistency and searchability. Uppercase letters are generally accepted but can make searching less efficient.
  • Hyphens: Separate words with hyphens (-) instead of underscores (_). This makes them easier to read in the command line and aligns better with search engine interpretations.
  • Descriptive names: Choose names that clearly reflect the content of the file or directory. This improves organization and understanding for yourself and others using the system.
  • Avoid generic names: Don't use generic names like "document1.txt". Be specific and descriptive for better organization.

Additional points:

  • File extensions: While not strictly required, using extensions like ".txt" for text files or ".docx" for documents helps identify file types quickly.
  • Maximum length: While most modern systems allow long names, some older systems might have limitations. It's good practice to keep names concise and informative.

C++ Functions

C++ Functions A function is a block of code that performs a specific task. Suppose we need to create a program to create a circle and color it. We can create two functions to solve this problem: a function to draw the circle a function to color the circle Dividing a complex problem into smaller chunks makes our program easy to understand and reusable. There are two types of function: Standard Library Functions:  Predefined in C++ User-defined Function:  Created by users In this tutorial, we will focus mostly on user-defined functions. C++ User-defined Function C++ allows the programmer to define their own function. A user-defined function groups code to perform a specific task and that group of code is given a name (identifier). When the function is invoked from any part of the program, it all executes the codes defined in the body of the function. C++ Function Declaration The syntax to declare a function is: returnType functionName (parameter1, parameter2,...) { // func...

C++ Variable

C++ Variables: Named Storage Units In C++, variables serve as named boxes in memory that hold values during program execution. Each variable has three key aspects: 1. Data Type: Defines the kind of data a variable can store: numbers (integers, floating-point, etc.), characters, boolean values (true/false), or custom data structures (arrays, objects). Common data types: int : Whole numbers (e.g., -10, 0, 23) float : Decimal numbers (e.g., 3.14, -2.5) double : More precise decimal numbers char : Single characters (e.g., 'a', 'Z', '&') bool : True or false values 2. Name: A user-defined label for the variable, chosen according to naming conventions: Start with a letter or underscore. Contain letters, digits, and underscores. Case-sensitive (e.g.,  age  and  Age  are different). Not a reserved keyword (e.g.,  int ,  for ). Choose meaningful names that reflect the variable's purpose. 3. Value: The actual data stored in the variable, which must match its data...

Interviews

  System analysis and design (SAD) interviews are a common assessment tool for software developer and system analyst roles. They evaluate a candidate's ability to understand problems, design solutions, and think critically about systems. Here's a breakdown of what to expect in a SAD interview: Purposes of SAD Interviews Evaluate problem-solving skills:  These interviews assess how you approach a problem, gather information, and develop a solution ( https://career.guru99.com/software-design-interview-questions/ ) Gauge system design knowledge:  They test your understanding of system architecture, scalability, databases, and trade-offs involved in design decisions. Assess communication skills:  Being able to clearly explain your thought process and design choices is essential in SAD roles. Types of SAD Interview Questions System design basics:  These might cover the CAP theorem, scaling strategies, or database selection criteria. ( https://www.interviewbit.com/sys...
