(Q10) Write C program to check whether a given year is a leap year.
(Hint: Every year that is exactly divisible by four is a leap year, except for years that are exactly
divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. ... The years 1600, 2000 and 2400 are leap years, while 1700, 1800, 1900,
2100, 2200 and 2300 are not leap years)
(Q11) Body constitution is measured using BMI (Body Mass Index) which depends only on the height and weight of a person. It can be defined by,
BMI = weight / height2
Where weight is taken in kilograms and height in meters. Four general grades are proposed such that,
Underweight : BMI < 18.5
Normal weight : 18.5 <= BMI < 25.03
Overweight : 25.0 <= BMI < 30.0 Obesity : 30.0 <= BMI
Write a C program to output user’s body constitution grade when he/she inputs body weight (kg) and the height (m).

(Q13) Implement the following game using while loop.
User will have a number between 0 and 100 in his or her head. Write a C program to guess that number. Program will guess a
number and users will say whether it is too high, too low, or that’s the number. At the end, print how many guesses it took to get right number. Note: You will have to
choose how your program will strategically guess. A naïve strategy can be to simply start the guessing at 1, and keep going (2, 3, 4, etc.) until you hit the number. But
that’s not an optimal guessing strategy. You need to provide an optimized solution.
