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_forward
- Microwaves / 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.

Directions: In this program you will ask the user for 4 integers that represtent two fractions. First ask for the numerator of the first and then the denominator. Then ask for the numerator and denominator of the second. Your program should add the two fractions and print out the result. For example: a sample program run might look like this, Numerator One: 1 Denominator One: 2 Numerator Two: 2 Denominator Two: 5 The sum is 9/10 //remember if you have two fractions, the following formula should be used: a/b + c/d = (a*d +b*c) / b* d public class MyProgram { public static void main(String[] args) { //Ask the user for 4 numbers. (don't forget to import your Scanner class) //create your final numerator //create your final denominator //print out your result like the example abovearrow_forward
- 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).

To get the bonus, the customer is given the opportunity three times to guess a number determined by the application from numbers 1 to 20. For each guess number given by the customer, the application will respond as follows:• If the guessed number is smaller than the lucky number, you will see the words "Bigger Number"• If the guessed number is greater than the lucky number, you will see the words "Smaller Number"• If the guessed number is the same as a lucky number, it will match the words "Congratulations ... you found a LUCKY number"As part of the company's IT team, you serve to create a lucky number guessing game console.A.

- This example creates a program to teach a first grade child how to learn subtractions. The program randomly generates two single- digit integers number1 and number2 with number1 > number2 and displays a question such as "What is 9 – 2?" to the student. After the student types the answer, the program displays a message to indicate whether the answer is correct.arrow_forwardLAB ASSIGNMENTS, CONT. 2. sandwich.py - follow the instructions below. You may adjust the food items to include your personal favorites. • It uses all of our standard mipo_ex features. • The menu should have numbered or letter options. Sandwich Maker Write a program that asks users for their sandwich preferences. The program should use PylnputPlus to ensure that they enter valid input, such as: Using inputMenu() for a bread type: wheat, white, or sourdough. Using inputMenu() for a protein type: chicken, turkey, ham, or tofu. Using inputYesNo() to ask if they want cheese. If so, using inputMenu() to ask for a cheese type: cheddar, Swiss, or mozzarella. Using inputYesNo() to ask if they want mayo, mustard, lettuce, or tomato. Using inputlnt() to ask how many sandwiches they want. Make sure this number is 1 or 120 00T 110 more. Come up with prices for each of these options, and have your program display all the choices and their prices plus a total cost at the very end. 3 130arrow_forwardIN VISUAL BASIC, solve: 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.
