Question

It is a part of code I am working on for assignment. When I execute the file, it asks if I am watching the game or not. Then I press Yes, yes, No or no. But it keeps asking me "Please enter only Yes or No: " no matter what I type in.

What is the problem???

1. int watch_stat() {

2. string watch;                                                                           //prompting watch status

3. cout << "Would you like to watch the game? (Yes or No) :";

4. cin >> watch;

5. while (watch != "Yes" || watch != "yes" || watch != "no" || watch != "No") {

6. cin.clear();

7. cin.ignore(100, ' ');

8. cout << "Please enter only Yes or No :";

9. cin >> watch;

10. }

11. int watchreturn;

12. if (watch == "Yes" || watch == "yes") {

13. watchreturn = 1;

14. }

15. else {

16. watchreturn = 0;

17. }

18. return watchreturn;

19. }

Explanation / Answer

please replace

while (watch != "Yes" || watch != "yes" || watch != "no" || watch != "No")

with

while (watch != "Yes" && watch != "yes" && watch != "no" && watch != "No")

i.e the while loop condition should be true if

watch is not Yes and watch is not yes and watch is not no and watch is not No
