Answer 1

You are converting a to an int but your switch statement is matching it to strings. Change it to case 1: instead of case "1" to fix the issues.

Answer 2

Remove quotes in case. i.e.

Replace case "1": with case 1:

Answer 3

The offending code are your case statements. a is an int. Your case statements all use strings. Simply remove the quotes around the numbers:

switch(a)
{
    case 1: 
            // some code
            break;
    case 2: 
            // some code
            break;
    // rest of cases
}
