You are using '1','2'.....etc that's wrong because it's for the character...
For integer...
just write 
1
2
3
4
5
6
7
8
 
case 1:
         //cout your statement 
         break;
case 2:
         //cout your statement 
         break;
...........................................
...........................................

so on...

Try to put your line:
r = num / 10;
AFTER
cin>>num;
You have it before, and if you do the division before receiving the user's input, num will have garbage data and the resulting value of r will be wrong.
