Documentation / APIs / C

Welcome to the C programming language API documentation! 🧠

📘 Introduction

C is a powerful, general-purpose programming language that serves as the foundation for many other languages and systems. It's ideal for system programming, embedded development, and performance-critical applications. 💻

• Key Characteristics
  • Compiled language
  • Low-level memory manipulation 📦
  • Minimal runtime environment ⚙️
  • Portable across platforms 🌍

📦 Core Features

Here are the essential components of C APIs:

1. Data Types

   • int, float, char, double etc.
   • Explore C data types in-depth

2. Operators

   • Arithmetic (+, -, *, /)
   • Logical (&&, ||, !)
   • Bitwise operations 🔁

3. Control Structures

   • if-else, switch, for, while
   • Learn about control flow

4. Memory Management

   • malloc, calloc, realloc, free
   • Best practices guide

🧪 Usage Examples

#include <stdio.h>
int main() {
    printf("Hello, World!\n"); // Simple output 📢
    return 0;
}

• File I/O

  FILE *file = fopen("example.txt", "r"); // File handling 📁
  

• String Manipulation

  char str[50] = "C is awesome!"; // String operations ✏️
  

⚠️ Common Issues

• Segmentation Fault 🚨
  Avoid dereferencing null pointers or accessing out-of-bounds memory.

• Pointer Confusion 🌀
  Always use const for unmodifiable data.

• Compiler Errors 🛠️
  Check syntax rules and include necessary headers.
