Rate of Inflation
The annual rate of inflation is the rate at which money loses its value. For example, if the annual rate of inflation is 3.0 percent, then in one year it will cost $1,030 to buy the goods that could have been purchased for $1,000 today. Put another way, a year from now $1,000 will only buy 1/1.03 * $1,000, or $970.87, worth of goods. Two years from now, $1,000 will only buy only 1/1.03 of $970.87, or $942.59 worth of goods. Write a

Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure 3.7a.(Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is 2(x2 - x1)2 + (y2 - y1)2. Test yourprogram to cover all cases.) Two sample runs are shown below: Enter a point with two coordinates: 4 5Point (4.0, 5.0) is in the circleEnter a point with two coordinates: 9 9Point (9.0, 9.0) is not in the circlearrow_forwardCredit Card Number Check. The last digit of a credit card number is the check digit, which protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:• Starting from the rightmost digit, form the sum of every other digit. For example, if thecredit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.• Double each of the digits that were not included in the preceding step. Add all digits ofthe resulting numbers. For example, with the number given above, doubling the digits,starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these valuesyields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27.• Add the sums of the two preceding steps. If the last digit of the result is 0, the number isvalid. In our case, 23 + 27 = 50, so the number is valid.Write a program that implements this…arrow_forward

For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.arrow_forward(Simulation) Write a program to simulate the roll of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like, with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)arrow_forward
- (Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.arrow_forwardSalary Calculator Create a program that computes the salary based on an employee's hourly wage and hours worked. Note that employees may work for fractions of an hour, e.g. 1 and a half hours (1.5 hours). Use the following formulas: Less than or equal to 40 hours worked hourly wage * hours worked Over 40, but less than or equal to 65 hours worked (hourly wage * 40) + (hours worked - 40) * (hourly wage * 1.5) Over 65 hours worked (hourly wage * 40) + (hourly wage * 1.5) * 25 + (hours worked - 65) * hourly wage * 2 Also make sure that the hourly wage and hours worked are positive. Otherwise, display the error message: "Invalid input". Please see the sample outputs below to guide the design of your program. main.cc file #include <iomanip> #include <iostream> int main() { // TODO: accept user input to store the hourly wage and hours worked. // Then, include the header file at the top of this file so you can // call your function that computes a…arrow_forwardQuestion # 4: Write a program that calculates the electricity bill.

- To make telephine numbers easier to remember, some companies use letters to show their telephone number. For example, the telephine number 438-5626 can be shown as GET-LOAN. In some cases, to make a telephone number meaningful, compaines might use more than seven letters. For example, 225-5466, can be displayed as CALL-HOME, whic uses eight letters. Write a program that prompts the user to enter a telephone number expressesd in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letter, then process only the first seven letters. Also, output the -(hyphen) after the third digit. Allow the user to use uppercase and lowercase letters, as well as spaces between words. Moreover, your program should proces as many telephone as the user wants. (Hint: You can read the entered telephine number as a string and then use the charAt() to extract each character.)arrow_forwardALPHABETIC TELEPHONE NUMBER TRANSLATOR Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Create an application that lets the user enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663. **the code below gives me an error, can't find where its wrong.** string str = textBox1.Text; const int SIZE = 12; Boolean valid = true; string newStr = ""; if (str.Length != SIZE) {…arrow_forwardAlphabetic Telephone Number Translator Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember.
