🧠 C Programming Data Types – One Shot Guide for Developers 🚀

Whether you're starting with C or brushing up your knowledge, understanding data types is foundational. Here's your quick yet deep dive into C Data Types—all in one shot! 💡

📌 What are Data Types in C?
Data types in C tell the compiler what kind of data a variable will store (e.g., integers, characters, floating points). They're essential for memory management, type checking, and operations.

🔸 Type Modifiers
C provides modifiers to adjust the size/range of base types:

short int     // Smaller integer
long int      // Larger integer
unsigned int  // Only positive
signed int    // Includes negative

🧪 Example:

unsigned int age = 25;
short int temp = -30;
long int population = 1000000;

🔘 Enumeration (enum)
Used to define a set of named constants.

enum week {Mon, Tue, Wed};

💡 Tips
Always choose the smallest data type that fits your needs.
Use sizeof() to check memory usage.
Prefer unsigned when negative values are not needed for optimization.

📘 Example Code

#include <stdio.h>

int main() {
    int age = 20;
    float gpa = 3.75;
    char grade = 'A';
    const int MAX = 100;

    printf("Age: %d\n", age);
    printf("GPA: %.2f\n", gpa);
    printf("Grade: %c\n", grade);
    printf("Max value: %d\n", MAX);

    return 0;
}

✅ Final Words
Understanding data types helps you write efficient, safe, and fast programs in C. Keep practicing by using different types in small programs.
