Q no 2 Answer:
Pseudo code:
Mobile_Usage //Main algorithm for determining the mobile use and display warning message
Get mobile_usage_in_min
//Checking if mobile_usage_in_min is less than 1 hour (Since 1 hour is equal to 60 minutes)
IF mobile_usage_in_min < 60 THEN
DISPLAY "Usage is acceptable"
//Checking if mobile_usage_in_min is greater than or equal to 1 hour and less than 2 hours
ELSE IF 60 <= mobile_usage_in_min && mobile_usage_in_min < 120
DISPLAY "Mediocre Usage"
//Checking if mobile_usage_in_min greater than 2 hours or not
ELSE IF 120 < mobile_usage_in_min
DISPLAY "Warning, using your phone more than 2 hours per day can affect your health"
