Currently when an animal other than a cat or dog is entered (such as a hamster), the program asks if it is spayed or neutered before displaying the message that only cats and dogs need pet tags. Find a way to make the program only execute the spay/neuter prompt and input when the pet type is cat or dog.

int main()  {

   string pet;        //stores the pet string which is cat or dog

   char spayed;     // stores the choice from y or n

   cout << "Enter the pet type (cat or dog): ";  //prompts user to enter pet type

   cin  >> pet;  //reads the input from user

   if(pet=="cat"|| pet=="dog")     { // if user enters cat or dog

   cout << "Has the pet been spayed or neutered (y/n)? ";

//asks user about pet been spayed of neutered

   cin  >> spayed;}  //reads y or n input by the user

   else  // else part will execute if user enters anything other than cat or dog

   cout<<"only cats and dogs need pet tags";

// displays this message if input value of pet is other than cat or dog

Explanation:

The answer to the complete question is provided below:

#include <string>

using namespace std;  

int main()  {

   string pet;         // "cat" or "dog"

   char spayed;        // 'y' or 'n'        

   // Get pet type and spaying information

   cout << "Enter the pet type (cat or dog): ";

   cin  >> pet;

   if(pet=="cat"|| pet=="dog")     {

   cout << "Has the pet been spayed or neutered (y/n)? ";

   cin  >> spayed;}

   else

   cout<<"only cats and dogs need pet tags";      

   // Determine the pet tag fee  

   if (pet == "cat")

   {  if (spayed == 'y' || spayed == 'Y')  //lowercase or upper case y is accepted

         cout << "Fee is $4.00 \n";

      else

         cout << "Fee is $8.00 \n";

   }

   else if (pet == "dog")

   {  if (spayed == 'y' || spayed=='Y')

         cout << "Fee is $6.00 \n";

      else

         cout << "Fee is $12.00 \n";

   }      

   return 0;   }

According to part a) of this question the OR operator is used in this statement      if (spayed == 'y' || spayed=='Y')  so that if the user enters capital Y or small y letter both are acceptable.

According to the part b)    if(pet=="cat"|| pet=="dog") statement is used to make program only execute spay/neuter prompt and input when the pet type is cat or dog otherwise the program displays the message: only cats and dogs need pet tags.
