Code on variables and Datatypes :

#include <stdio.h>

int main() {
    // Integer data types
    int integerVar = 42;
    short int shortVar = 12345;
    long int longVar = 1234567890L;
    long long int longLongVar = 123456789012345LL;

    // Floating-point data types
    float floatVar = 3.14159;
    double doubleVar = 2.718281828459045;
    long double longDoubleVar = 1.2345678901234567890L;

    // Character data type
    char charVar = 'A';

    // Boolean data type (C99 and later)
    _Bool boolVar = 1; // true
    
    // Enumeration data type
    enum Color { RED, GREEN, BLUE };
    enum Color favoriteColor = BLUE;

    // Output values
    printf("Integer: %d\n", integerVar);
    printf("Short Integer: %hd\n", shortVar);
    printf("Long Integer: %ld\n", longVar);
    printf("Long Long Integer: %lld\n", longLongVar);

    printf("Float: %f\n", floatVar);
    printf("Double: %lf\n", doubleVar);
    printf("Long Double: %Lf\n", longDoubleVar);

    printf("Character: %c\n", charVar);

    printf("Boolean: %d\n", boolVar);

    printf("Favorite Color: %d\n", favoriteColor);

    return 0;
