Description

Suppose we have several student’s scores and we want to develop a program that calculate the average score.

Requirements:

User inputs score one by one.

The score is a positive or zero integer value.

When user inputs a negative value, the program calculates the mean score and is finalized. The mean score is rounded off to the first decimal place.

This task could be broken down into the following procedures:

1. Initialize variables to store the number of student and the sum of score. (‘count=0’ and ‘sum=0’)
2. Start a loop
3. Get a student’s core. (cin >> score)
4. If the core is negative, exit from the loop. (go to 8)
5. Add the score to the sum. (sum += score)
6. Increment the counter. (count++)
7. Go back to 3
8. Compute the mean score. (mean = sum / count)
9. Print the result.

 

Part 2

We develop “Buying Soda” code similarly with “Buying Pizza” code.  (See Sample) What size Soda is the best buy?

Which size gives the lowest cost per a little?

Soda sizes given in little.

Quantity of soda is based on the volume. Buying Soda Problem Defini on

Input:

Volume of two sizes of soda.

Cost of the same two sizes of soda.

Output:

Cost per a unit volume for each size of soda.

Which size is the best buy,

Based on lowest price per a unit volume,

If cost per a unit volume is the same, the smaller size will be the better buy.
