Answer 1

@user2409559 , @Dinever; First,no need of % in ur code as u are taking i/p as first and second digits. Second your code is incomplete. Enter a number b/w 10 to 19 and see the o/p.

I am posting my code below.......take a look.

#include 
#include 

int main()
{
int num,n,r;

printf("Enter a two-digit number: ");
scanf("%d",&num);

n = num/10;
r = num%10;

switch(n)
{ 
    case 1: switch(r)
            {
                case 0: printf("Ten");
                        break;   
                case 1: printf("Eleven");
                        break;
                case 2: printf("Twelve");
                        break;
                case 3: printf("Thirteen");
                        break;
                case 4: printf("Fourteen");
                        break;
                case 5: printf("Fifteen");
                        break;
                case 6: printf("Sixteen");
                        break;
                case 7: printf("Seventeen");
                        break;
                case 8: printf("Eighteen");
                        break;
                case 9: printf("Nineteen");
            }
            break;                                    
    case 2: printf("Twenty-");
            break;
    case 3: printf("Thirty-");
            break;
    case 4: printf("Fourty-");
            break;
    case 5: printf("Fifty-");
            break;
    case 6: printf("Sixty-");
            break;
    case 7: printf("Seventy-");
            break;
    case 8: printf("Eighty-");
            break;
    case 9: printf("Ninety-");
            break;
}
if(n != 1)
{
     switch(r)
     {
         case 1: printf("one");
                 break;
         case 2: printf("two");
                 break;
         case 3: printf("three");
                 break;
         case 4: printf("four");
                 break;
         case 5: printf("five");
                 break;
         case 6: printf("six");
                 break;
         case 7: printf("seven");
                 break;
         case 8: printf("eight");
                 break;
         case 9: printf("nine");
                 break;
         default: ;                         

     }
}
getch();
