Largest Digit

This one is a bit tricky. You're going to have to isolate each digit of the integer to determine which one is the largest, so good luck!

Instructions:

1. Input a 3-digit integer.
2. Print the largest digit in the integer.
3. Tip #1: Use % 10 to get the rightmost digit. For example, if you do 412 % 10, then the result would be the rightmost digit, which is 2.
4. Tip #2: On the other hand, use / 10 to remove the rightmost digit. For example, if you do 412 / 10, then the result would be 41.
5. Tip #3: You'd have to repeat Tip #1 and Tip #2 three times for this problem because the input is a 3-digit integer.

Instructions

1. Input one 3-digit integer.
2. Print the largest digit in the integer. (Hint: use % 10 to get the rightmost digit and / 10 to remove it)

Input

A line containing a three-digit integer.

173

Output

A line containing a single-digit integer

Write an application for a lawn-mowing service. The lawn-mowing season lasts 20 weeks. The weekly fee for mowing a lot under 4,000 square feet is R25. The fee for a lot that is 4,000 square feet or more, but under 6,000 square feet, is R35 per week. The fee for a lot that is 6,000 square feet or over is R50 per week. Prompt the user for the length and width of a lawn USING JOPTIONPANE, and then display the weekly mowing fee USING JOPTIONPANE , as well as the 20-week seasonal fee. Save the file as Lawn.java.

Write a simple c++ program that will display the area and circumference of a circle with a radius of 5. Note the program must implement copy constructors. 

Write a ‘C++’ program (capable of being compiled on any standard ‘C++’ compiler and

in particular Bloodshed Dev-C++ compiler, the one that we use for our course.

The program will need to calculate the final mark and corresponding grade and letter

grade based on the information given below. 

3.1 Write a Java program that will compute the future investment value at a given interest rate for a specified number of years. The java program should have a minimum of two classes.

3.1.1 classA

 The main method (starting point) (5)

 The object of classb (5)

 Should also call the void method named futureInvestmentValue (double investment Amount, double monthlyInterestRate, int years) (15)

3.1.2 classB

 A get method named count_words(String str) (15)

Expected Output:

Input the investment amount: 28000

Input the rate of interest: 7

Input number of years: 6
