C Organize Code As C projects grow, organizing code becomes essential to maintain readability, reusability, and easy debugging.Instead of writing everything in a single .c file, larger programs are divided into: ✔ Source files...

C Preprocessor and Macros The C Preprocessor runs before the actual compilation of the program.It processes instructions beginning with the # symbol, called preprocessor directives. These directives help include files, define constants, create macros,...

C Random Numbers In C, random numbers are generated using functions from the <stdlib.h> library.To make results less predictable, we often combine them with time() from <time.h>. 📌 Functions Used Function Purpose rand() Generates...

C Date and Time In C programming, working with date and time is done using functions defined in the <time.h> library. This library allows you to: Get the current date and time Format date/time...

🛡️ C Input Validation Input validation ensures that the user enters correct, safe, and expected values.It prevents: Runtime errors Crashes Unexpected behavior Security issues Since C does not automatically validate input, programmers must manually...

⚠️ C Error Handling Unlike some modern languages, C does not have built-in exception handling (like try-catch).Instead, C uses several alternative mechanisms for detecting and managing errors manually. 🔹 Methods of Error Handling in...

🔹 C NULL NULL is a special constant in C used to represent a null pointer, meaning the pointer does not point to any valid memory location. It is defined in multiple header files...

🐞 C Debugging Debugging is the process of identifying and fixing errors (bugs) in a C program. Errors can be logical, runtime, or compile-time. Debugging helps ensure the program behaves as expected. 🔍 Why...

📌 C Errors In C programming, errors occur when the code violates rules of the language or tries to perform invalid operations.Errors prevent the program from compiling or running correctly. C errors are mainly...

📌 C Memory Management Example (Complete Program) Here is a full practical example demonstrating malloc, calloc, realloc, and free all in one program. ✅ Full Example: Dynamic Array with Memory Operations #include <stdio.h> #include...
