Answer 1

It appears that you have an issue with your code where the value of right_answer is being overwritten in each iteration of the loop. As a result, the same answer is being checked against each of the capital cities.

To fix this issue, you could store the answers in an array or a separate variable for each capital city. Then, you can check the answers against the corresponding capital city.

Answer 2

If you taking input in variable then it's previous value will be overridden by new value. So last input about "Capital in Australia ", will be exits. Previous values are just useless inputs..

Take a string array.
string right_array[5]; next use array cin>>right_array[i++] ;
// before intialize int i=0;

Seems there are more mistakes..
Try changes, if you need..
Save code and share link..
