Modify the program to include twocharacter com names where t

Modify the program to include two-character .com names where the second character can be a letter or a number, as in a2.com. Hint: Add a second loop, following the while (letter2 <= \'z\') loop, to handle numbers.

#include <iostream>
using namespace std;

/* Output all two-letter .com Internet domain names */

int main() {
   char usrInput = \'?\';
   char letter1 = \'?\';
   char letter2 = \'?\';

   cout << endl << \"Two-letter domain names:\" << endl;

   letter1 = \'a\';
   while (letter1 <= \'z\') {
      letter2 = \'a\';
      while (letter2 <= \'z\') {
         cout << letter1 << letter2 << \".com\" << endl;
         ++letter2;
      }
      ++letter1;
   }

   return 0;
}

Solution

#include <iostream>
using namespace std;
/* Output all two-letter .com Internet domain names */
int main() {
char usrInput = \'?\';
char letter1 = \'?\';
char letter2 = \'?\';
cout << endl << \"Two-letter domain names:\" << endl;
letter1 = \'a\';
while (letter1 <= \'z\') {
int i=0;   
letter2 = \'a\';
while (letter2 <= \'z\') {
cout << letter1 << letter2 << \".com\" << endl;
++letter2;
}
while(i<=9){
cout << letter1 << i << \".com\" << endl;
++i;
  
}
++letter1;
}
return 0;
}
