Problem 5

1. A C++ teacher wants to find how many students he has in his classroom. He did the following to discover the number:

a. When he forms groups of 4, he is left with one group of 3 students

b. When forming groups of 3, he is left with one group of 2 students

c. Finally when forming groups of 5, no odd group is left. All groups have five students.

Write a program to help the teacher find how many students in his classroom.

2. Loops, again!

a. Write a while loop, that adds 5 to n for as long as n is smaller than 15

b. What would the value of n be at the end of the loop if n = 3 before the loop?

c. What would the value of n be at the end of the loop if n = 21 before the loop?
