Write Visual Basic program that asks the user to enter a 10-character telephone number in the format of XXX-XXX-XXXX. The program should display the number with any alphabetic characters translated into the number equivalent. For example, if the user enters 555-GET-FOOD, the result should be 555-438-3663. Many companies use telephone numbers like 555-GET-FOOD so the number if easier to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following manner: A, B, C = 2 D, E, F = 3 G, H, I = 4 J, K, L = 5 M, N, O = 6 P, Q, R, S = 7 T, U, V = 8 W, X, Y, Z = 9
