Example:
if ( temp > 32 && temp < 50 )
isChilly = true;
if ( temp < 32 || temp > 90 )
yuckyWeather = true;

13. Your task… New project named bool Write a program that :
Asks the user a yes/no question
Loops until the user has entered a valid answer
Which logical operator do you need to use in the loop condition check?
Is this an “and” or an “or” question?

14. Your task continued… Add to your bool project…
Asks the user the yes/no question again
Loop until the user has entered a valid answer
This time, use a single bool variable as the loop control variable
