Question

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;
}

Explanation / Answer

#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;
}
