2.1 Purpose of the Code:
The purpose of this segment of code is to calculate the sum of the integers from
0 to 5 (inclusive) and store the result in the variable s. The variable n starts at 0
and is incremented by 1 in each iteration of the while loop until it becomes
greater than 5, with each value of n being added to s.
2.2 Purpose of the Code:
The purpose of this segment of code is to count how many non-zero elements
are present in the array numbers. The loop iterates through all the elements of
the array, and for each non-zero element, the counter c is incremented by 1.
After the loop completes, c contains the total number of non-zero elements in the
array.
