Alphabetic 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

- Word Sleuth Puzzle Programarrow_forwardC++ Language Write a program that prints a custom conversion table from Celsius temperatures to Fahrenheit and Newton (Links to an external site.) temperatures. The formula for the conversion from Celsius to Fahrenheit is : F=9/5*C+32 F is the Fahrenheit temperature, and C is the Celsius temperature. The formula for the conversion from Celsius to Newton is C = 100/33*N N is the Newton Temperature and C is the Celsius temperature Your program should prompt the user for a lower value and upper value for a range of temperatures in Celsius. It should then prompt the user for the amount they want to increment by. Then use a loop to output to a file named conversion_table.txt a table of the Celsius temperatures and their Fahrenheit and Newton equivalents within the range of values using the increment given by the user. Make sure to format your output to 2 decimal places. INPUT VALIDATION: Ensure the second number is greater than the first number, and make sure the increment is greater…arrow_forwardMatric Number: 2. Let x be the first three digits of your matric number, AND y be the last three digits of your matric number. If the first digit of y is 0, replace it with 2. Ехатple: If you matric number is 2013034, Thus, x = 201 and y = 234 a. Write the values of x and y based on your matric number. b. If a = x (mod 7) and b = (-1) + y (mod 7), find the integer(s) c with 10arrow_forwardMicrowaves / Radio Waves If a scientist knows the wavelength of an electromagnetic wave she can determine what type of radiation it is. Write a program that asks for the wavelength in meters of an electromagnetic wave and then displays what that wave is according to the following chart. (For example, a wave with a wavelength of 1E-10 meters would be an X-ray.) 1x 10-11 1 x 10-8 4 x 10-7 7x 10-7 1x 10-3 1 x 10-2 Gamma Rays.

The president has asked you to program the new system. You are to write a program to assign seats on each flight of the airline's only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1-5). If the person types 2, then your program should assign a seat in the economy section (seats 6-10). Your program should then print a boarding pass indicating the person's seat number and whether it is in the first class or economy section of the plane. Use a single-subscripted array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of…arrow_forwardDiscrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table; Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6 After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2). Draw a rooted tree that represents your expression. What is the prefix form of this expression. 3.What is the value of the prefix expression obtained in step 2 above?arrow_forwardMonty Hall Problem – Coding Lab In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a doornumber (different from the one the user picked) with a goat behind it and ask theuser if they would like to change their choice. The code then displays a message onwhether the user guessed the correct door. The game then…arrow_forwardmessage-passing (MPI) libraries Triangular number Series: A triangle number counts the objects that can form an equilateral triangle. The nth triangle number is the number of dots or balls in a triangle with n dots on a side; it is the sum of the n natural numbers from 1 to n. • The formula for the nth triangular number can be expressed as: ?? = ∑ ? ? ?=1 = 1 + 2 + 3 + ⋯ + ? = ?(? + 1) 2 = ( ? + 1 2 ) • The first few triangular numbers are: 0, 1, 3, 6, 10, 15, …… • Pictorially, the triangular numbers can be represented as below: Write a program that generates the triangular number series from the first term up until the n th term. In your program, the user will enter the n number, choose a large number! The sequence should be printed in the correct order. Regarding the number of threads/processes, try at least three different numbers (e.g., 2, 4, 8).arrow_forwardLab: switch Note: switch syntax is only applied for service selection. You can use if – else syntax for other comparison. Using switch syntax to write a program that calculates and prints the bill for a cellular telephone company. The company offers two types of service: regular and premium. Its rates vary, depending on the type of service. The rates are computed as follows: Regular service: $10.00 plus first 50 minutes are free. Charges for over 50 minutes are $0.20 per minutes. Premium service: $25 plus For calls made from 6:00 a.m to 6:00 p.m., the first 75 minutes are free; charges for more than 75 minutes are $0.10 per minute. For, calls made from 6:00 p.m. to 6:00 a.m., the first 100 minutes are free; charges for more than 100 minutes are $0.05 per minute. Your program should prompt the user to enter an account number, a service code (type char), and the number of minutes the service was used. A service code for r or R means regular service; a service…arrow_forwardQ1: Write a program that reads 10 numbers and then finds the largest number and prints it and finds the smallest number and eyarrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.)
