Description

Write a program that translates a letter used in a telephone number into an equivalent numeric digit. The program asks the user to enter a letter, translates the letter into the corresponding digit and displays it. The user may enter its selection either as an upper or lower case letter.

The program translates the letter into a digit according to the table below:

Letters Digit

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

Testing

Input Test 1

Enter a letter: p

Output Test 1

Letter: p

Digit: 7

Input Test 2

Enter a letter: P

Output Test 1

Letter: P

Digit: 7

Sample Code 1

/*

The code below determines the character entered by user.

*/

/*

C++ code:

*/

char letter;

cout << Enter a single alphabet: << endl;

cin >> letter;

/*

Java code:

*/

/*

The code snippet below does the following:

It asks the user to enter a single alphabetical character

It saves the entered character in a string named in.

It extracts the first character from the String in.

It saves the extracted character in a char variable named letter.

*/

String in;

char letter;

int digit;

in = JOptionPane.showInputDialog(Enter a single alphabet);

letter = in.charAt(0);

Sample Code 2

/*

The code snippet below attempts to determine the digit corresponding to the letter.

Only a partially written Switch statement is shown. Add the additional cases.

*/

switch (letter)

{

case a:

case b:

case c:

case A:

case B:

case C:

digit = 2;

break;

case d:

case e:

case f:

case D:

case E:

case F:

digit = 3;

break;

}
