    // Different types of Variables in C:
    // int= whole numbers (4 bytes in modern systems)
    // float = single precision decimal number(4 bytes)
    // double = double precision decimal number(8 bytes)
    // char= single character(1 byte)
    // char[]= array of characters(size varies)
    // bool= true or false(1 byte, requires <stdbool.h>)

    // eg of int: int studentNumber= 23848254;
    // float: float time = 9.30;
    // double: double
    // char: char grade = "A"
    // char[]: char studentName[] = "Chris Jose"
    // bool: bool isWon = "true";

    printf("You are %d years old\n", age); //%d is the format specifier for the integer.
    printf("The year is %d\n", year);
    printf("You have ordered %d x items\n", quantity);
