Rewrite the above program Example . Telephone digits. Replace the statements from Line 10
to Line 28 so that the program uses only a switch structure to find the digit that
corresponds to an uppercase letter.
Explanation / Answer
please rate - thanks
most of that code was already a switch, I just added a default
#include <iostream>
using namespace std;
int main()
{
char letter;
cout << "Program to convert uppercase "<< "letters to their corresponding "
<< "telephone digits." << endl;
cout << "To stop the program enter #."<< endl;
cout << "Enter a letter: ";
cin >> letter;
cout << endl;
while (letter != '#')
{
cout << "The letter you entered is: "<< letter << endl;
cout << "The corresponding telephone "<< "digit is: ";
switch (letter)
{
case 'A':
case 'B':
case 'C':
case 'a':
case 'b':
case 'c':
cout << "2" <<endl;
break;
case 'D':
case 'E':
case 'F':
case 'd':
case 'e':
case 'f':
cout << "3" << endl;
break;
case 'G':
case 'H':
case 'I':
case 'g':
case 'h':
case 'i':
cout << "4" << endl;
break;
case 'J':
case 'K':
case 'L':
case 'j':
case 'k':
case 'l':
cout << "5" << endl;
break;
case 'M':
case 'N':
case 'O':
case 'm':
case 'n':
case 'o':
cout << "6" << endl;
break;
case 'P':
case 'Q':
case 'R':
case 'S':
case 'p':
case 'q':
case 'r':
case 's':
cout << "7" << endl;
break;
case 'T':
case 'U':
case 'V':
case 't':
case 'u':
case 'v':
cout << "8" << endl;
break;
case 'W':
case 'X':
case 'Y':
case 'Z':
case 'w':
case 'x':
case 'y':
case 'z':
cout << "9" << endl;
default: cout << "Invalid input." << endl;
}
cout << " Enter another uppercase "<< "letter to find its "
<< "corresponding telephone digit."<< endl;
cout << "To stop the program enter #."<< endl;
cout << "Enter a letter: ";
cin >> letter;
cout << endl;
}//end while
return 0;
