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
Write an application that asks the user to 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 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_forwardMatric Number: 2.

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_forwardCode in C++ Language STRING FLIP ALPHABET One of the simplest cryptography technique is to invert the characters such that the first character of the alphabet will be replaced to the last character, the second character be replaced to the second to the last, and so on. So all A's are turned into Z's, B to Y, C to X, and so on until X to C, Y to B, and Z to A. In a similar fashion, numeric characters will also be inverted such that 0 will become 9, 1 to 8, 2 to 7 and so on until 7 to 2, 8 to 1, and 9 to 0. Given a string composed of uppercase and lowercase letters, numbers, and spaces, your task is to invert them. You also must keep the case of the letters as is.

Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class for a point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the sample area() - computes and returns the area of a given rectangle perimeter() - computes and returns the perimeter of a given rectangle centerPoint() -…arrow_forwardCoral Help Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: The 90 is primary, going east/west. Ex: If the input is: 290 the output is: The 290 is auxiliary, serving the 90, going east/west. Ex: If the input is: 0 or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.arrow_forwardPython Language: Word Sleuth Programarrow_forwardC# language MORSE CODE CONVERTER Design a program that asks the user to enter a string and thenconverts that string to Morse code.

Programming challenge description: Little Tommy is in kindergarten on the first day of class. His teacher has taught him about inequalities today, and he is learning how to draw crocodiles to represent them. When there are two numbers, A and B, there are three options:1. If A is greater than B, then draw '>'. The crocodile's mouth is pointed toward the bigger number, A.2. If A is less than B, then draw '<'. The crocodile faces B.3. If A is equal to B, draw '='. The crocodile is confused and keeps its mouth shut.Unfortunately, Tommy does not like to do his homework, and has bribed you to write a program to do it for him. Input: The input consists of two integers A and B on a line, separated by a space. |A,B| < 2^63.
