Sample final solutions

Listed below are the solutions to the questions I posted for the sample final questions.

1. int equal(int a, int b, int c)
   {
     if (a == b || a == c || b == c) {
       return 1;
     }
     else {
       return 0;
     }
   }
   

2. int yearInCentury(int year)
   {
     return ((year - 1) % 100) + 1;
   }
   

3. int numberOfDigits(int n)
   {
     int digits = 0;
     while (n > 0) {
       n = n / 10;
       digits++;
     }
     return digits;
   }
   

4. void getMonthYear(int& month, int& year)
   {
     do {
       cout << "Enter the month: ";
       cin >> month;
     } while (month < 1 || month > 12);
   
     do {
       cout << "Enter the year: ";
       cin >> year;
     } while (year < 1960 || year > 2000);
   }
   

5. void exceeds(ifstream& inputfile, int limit, ofstream& outputfile)
   {
     int number;
     while (inputfile >> number) {
       if (number >= limit) {
         outputfile << number;
       }
     }
   }
