the item inside the switch() parenthesis must resolve to an int. That means each case must resolve to an int. 'Ja' is not an int. In fact it isn't anything. 'J' is a char and char are interpreted as ints by the computer so that works. "Ja" is a string, but not a char and not an int. 'Ja' however isn't anything. Use this syntax instead:

case 1:
case 3:
case 5:
days = 31;
break;

etc

First I would create an array of valid month names, such as

string months[] = {"January","February","March" ... };

Then after the user enter the month name just create a loop and compare them

int i;
for(i = 0; i < 12; i++)
{
   if( month_name == months[i] )
   {
        // found it
   }
}

After the above is complete, the value of the i counter is the month number that you can use in that switch statement

switch(i)
{
    case 0: // January
    case 2: // march
         days = 31;
   // etc.
}

On line 37 add cin >> month_name;.

Line 76 should refer to month, not m_number and isn't necessary since you already have m_number.

To get the name of the month to appear on line 121 you can use another switch() statement

switch(m_number)
{
  case 1:
     cout << "January";
     break;
  case 2:
     cout << "Febuary";
     break;
  etc
}
