Mastering C: fgets() for Safe String Input

Generic programming in C is not missing. It’s just not handed to you. You can fake it with void*, abuse the preprocessor, or use template-style macros. Or you can generate real code and debug it like normal C. I wrote a breakdown of all approaches and why I prefer code generation. https://lnkd.in/dAGvr-XX

VARIABLE: ▪️In the C programming language, a variable is a named storage location in memory used to hold a value that can change during program execution. SYNTAX: ▪️data type variable name; EX: int a=5; RULES FOR NAMING VARIABLES : 🔹must starts with letter (or) underscore 🔹cannot starts with numbers 🔹cannot use reserved words (like int,float,etc.) 🔹It can contain digits ,letters and underscores 🔹variables are case-sensitive (age and AGE are different) ◾EXAMPLES OF CREATING VARIBLES: 🔹 float a=52.2; ✅ 🔹 char ___ch1='b'; ✅ 🔹 int 1_age = 18; ❎ 🔹 float float = 123.32 ❎

Built a custom string handling class in C++ from scratch — without using std::string. This project focuses on: • Dynamic memory management using new[] and delete[] • Implementation of the Rule of Three (Destructor, Copy Constructor, Copy Assignment) • Manual string manipulation algorithms (reverse, case conversion, word counting) • Operator overloading for intuitive usage (+, +=, [], (), comparison operators) The goal was to deeply understand how strings work internally rather than relying on built-in abstractions. A great exercise in mastering memory management, object-oriented programming, and low-level string operations in C++. #cpp #programming #softwareengineering #oop #learning #developers

ARP is the procedure used by a network host to discover hardware access of another host in same physical network. ASN.1, abstract syntax notation one is a standard interface description language used to define data structures in a way that is independent of specific hardware annd programming languages.

Beyond std::thread: The C++20 Multithreading Revolution. -------------------------------------- C++20 represents a watershed moment for multithreading in the language. While C++11 gave us a solid foundation with std::thread, mutexes, and condition variables, C++20 has addressed many of the pain points that made concurrent programming error-prone and verbose. The headline feature—std::jthread—brings automatic resource management and standardized thread cancellation to the table. But the story doesn't end there: new synchronization primitives (std::latch, std::barrier, std::counting_semaphore), atomic wait/notify operations, and synchronized output streams collectively transform how we write robust, maintainable concurrent code.

✨ extern "C": Use C++ with C extern "C", is a powerful feature that allows C programs to be able to call functions written in C++. Learn more about how this exactly works and how to use it. https://lnkd.in/ghmTHS7i #CProgramming #Development #CPP

🚀 C++ Basic Syntax: Statements and Semicolons In C++, a statement is a complete instruction that the computer executes. Every statement in C++ must end with a semicolon (;). The semicolon tells the compiler where a statement ends. Forgetting the semicolon will result in a compilation error. This is a fundamental aspect of C++ syntax, ensuring the compiler can correctly parse and execute your code. #c++ #programming #coding #tech #learning #professional #career #development

C15 Union Types: finally, compiler-checked “either/or” results 🚨 Tired of returning object (or building awkward base classes) just to say “this method returns A *or* B”? C15 brings a real solution: union types. ✨ What clicking gets: ✅ How `union` declares a closed set of case types (even unrelated ones) ✅ Implicit conversions so assignments stay clean ✅ Exhaustive pattern matching—the compiler forces every case to be handled (no `_` / `default` safety blanket) ✅ A clear roadmap for broader exhaustiveness in C# 🧠 Example vibe: define `Pet(Cat, Dog, Bird)` once… then `switch` with confidence knowing every case is covered. If discriminated unions were missed in C#, this is the most C#-native take yet. 🔥 https://lnkd.in/dsu5t_8M #csharp #dotnet #programming #patternmatching #compilers

Solved a Gray Code problem in C++ today. The task was to generate bit patterns from 0 to 2^n - 1 such that every consecutive pattern differs by only one bit, while always starting from 0. I used the Gray code formula: gray = i ^ (i >> 1) This makes the solution clean and efficient, and guarantees that adjacent codes differ by exactly one bit. Example for n = 2: 00 -> 01 -> 11 -> 10 What I like about this problem is how a simple bit manipulation formula can solve what looks like a complex sequence-generation challenge.

Post No: 048 A small but interesting thing I recently got to know in C++ is how static_cast behaves with string literals. When I write “hello”, I thought it is a std::string, but it is not. A string literal in C++ is actually of type const char[]. In most expressions, this array decays into a pointer, which is why: auto text = “hello”; makes text a const char*, not a std::string. This is also why static_cast may seem to “cast it to a pointer”. What is really happening is array-to-pointer conversion. The important thing to understand is that std::string and std::string_view are class types. To create them, we need object construction. For std::string: std::string str = static_cast<std::string>(“hello”); For std::string_view: std::string_view sv = static_cast<std::string_view>(“hello”); We can also directly construct them in a cleaner way: std::string str(“hello”); std::string_view sv(“hello”); I got to learn this in a hard way, hope this makes things more easy for someone else. #cpp #cplusplus #programming #softwaredevelopment #coding #learning
