Q7: When a user is asked to input one digit, how can you test to make sure that a user entered only one? Assuming the user's input is stored in a variable named, digit, write the code that displays an appropriate error message. NOTE: Be sure to test for positive and negative values.

The user should be able to test different monthly deposit amounts, interest rates, and lengths oftime to see how increases and decreases impact their investment growth.4. Your code will need to account for the following:a. Month: The number of months based on user input in the “Number of Years” fieldb. Opening Amount: The initial investment amount as well as the opening balance eachmonth, which includes interestc. Deposited Amount: The dollar amount the user plans to deposit each month. This valuewill be the same every month for the duration of the investment.d. Total: The sum of the opening and deposited amountse. Interest: Money earned based on the “annual interest” rate input by the user. Theinterest based on an opening amount of $1 and a deposited amount of $50 with aninterest rate of 5% compounded monthly is:(Opening Amount + Deposited Amount) * ((Interest Rate/100)/12)OR(1 + 50) * ((5/100)/12)Note: Dividing by 100 converts the interest rate percentage to a decimal.Note: 12 is the…

Program Purpose - Professional Athletes often hire other professionals to help take care of matters for them. We will group them in four categories: Lawyers, Personal Assistants, Agents, and Trainers. They all get paid a percentage of the athlete's total yearly salary. Lawyers - 10%, Personal Assistants - 3%, Agents - 7%, and Trainers - 5% . Prompt the user to enter the athlete's salary for the year (ensure that the entered value is positive). The user should then enter the name and category of each of the hired professionals. The athlete should be able to hire as many professionals in each category as he/she wants, even if it is more than he/she can afford. Based on the category, calculate the amount that each professional should be paid. After all data has been entered, print the names of each professional hired, how much each is being paid, the total amount the athlete paid, and how much the athlete has left.

oe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should perform the following steps: Ask the user for the diameter of the pizza in inches. Calculate the number of slices that may be taken from a pizza of that size. Display a message telling the number of slices. To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 inches To calculate the number of slices, simply divide the area of the pizza by 14.125. The area of the pizza is calculated with this formula:   Area NOTE:  π is 3.14159. The variable r is the radius of the pizza. Divide the diameter by 2 to get the radius.

Assume that the population of Mexico is 128 million and the population of the United States is 323 million. Write a program called Population that accepts two values from a user: an assumption of an annual increase in the population of Mexico and an assumption for an annual decrease in the U.S. population. Accept both figures as percentages; in other words, a 1.5 percent decrease is entered as 0.015. Write an application that displays the populations of the two countries every year until the population of Mexico exceeds that of the United States, and display the number of years it took. An example of the program is shown below: Enter the percent annual increase for Mexico population Enter as a decimal. For example, 0.5% is entered as 0.005 Enter the value >> 0.008 Enter the percent annual decrease for U.S. population Enter as a decimal. For example, 0.5% is entered as 0.005 Enter the value >> 0.002 Mexico population U.S. Population 1 129.024 million 322.354 million 2…
