⮚ Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M. ⮚ Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000.⮚ For example, 2 is written as II in Roman numeral, just two ones added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II. ⮚ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. X can be placed before L (50) and C (100) to make 40 and 90. C can be placed before D (500) and M (1000) to make 400 and 900. ⮚ Given a roman numeral, convert it to an integer

- Understanding if Statements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge).

- Language: JAVA PLEASE DO QUESTIONS 2 AND 3 ONLY PIN Lockout Write a code to enter a 4-digit PIN as an integer, and check if the pin is valid (the valid PIN is 1234). If the PIN is not valid print an error message “INCORRECT PIN. TRY AGAIN.” and let the user enter the PIN again. But the user only has 3 tries to enter the correct PIN. If the user enters the wrong PIN for his/her 3 tries then print “YOU HAVE RUN OUT OF TRIES. ACCOUNT LOCKED.” And if the user enters the valid PIN within the 3 tries print “PIN ACCEPTED. YOU NOW HAVE ACCESS TO YOUR ACCOUNT.” Use a while loop to prompt the user to enter a valid PIN. Do not forget to print a prompt for the user asking to enter the PIN. Create a class named PinLockout which will have the main method. All your code goes inside the main method. Sample input and output: Sample 1: ENTER YOUR PIN: 2345 INCORRECT PIN. TRY AGAIN.
