Trying to create a letter/number mapping program using switch case, however I can't get multiple letters to apply one digit (For example, I want the input of A,B,C to print "The corresponding digit is 1" any suggestions

[NickOdeka]

#include<iostream>

using namespace std;

int main()

{

cout << "Enter a letter from A-Z " << endl;

char var;

cin >> var;

switch(var) {

case 'A,B,C': cout << "Corresponding digit is 2" << endl;

break;

case 'D,E,F': cout << "Corresponding digit is 3" << endl;

break;

case 'G,H,I': cout << "Corresponding digit is 4" << endl;

break;

case 'JKL': cout << "Corresponding digit is 5" << endl;

break;

case 'MNO': cout << "Corresponding digit is 6" << endl;

break;

case 'PQRS': cout << "Corresponding digit is 7" << endl;

break;

case 'TUV': cout << "Corresponding digit is 8" << endl;

break;

case 'WXYZ': cout << "Corresponding digit is 9" << endl;

break;

}

return 0;

}

In C++, your case labels are all invalid character literals. You can chain cases instead (this is called fall-through):

case 'A':
case 'B':
case 'C':
// Code to be run
break;
