What happens if the condition in a while loop is initially false? Explain and differentiate
between while and do while statement in ‘C’ language.
What is an expression? What are its components? Explain.
Write a program that takes as input a class score. Output the grade for the class based on the
following guideline:
Exactly 100 is A+
90and above is A
80 and above is B
70 and above is C
60 and above is D
Anything less than 60 is F
Anything more than 100 or less than 0 is invalid input.
Write a program that accepts a letter grade as input and outputs the teacher’s remarks. Use
only switch, do not use any if’s. Example: If ‘A’or ‘a’, then “Excellent job!”. If ‘F’ or ‘f’, then “You

Imagine a collection of nuts and bolts that are all together in one pile on a table. Describe, in pseudocode, how you would find all matching pairs of nuts and bolts. You need to find one solution for each of the problem-solving approaches given below. For each of your solution, determine how many comparisons of pairs of nuts and bolts you might have to make in the best- and worst- case scenario. You can assume that there are complete pairs, no single nuts or bolts, and that for each bolt, there is exactly one nut that fits. Describe a solution to the nuts and bolts problem (in pseudocode) using a Divide and Conquer Approach.
