Suppose we have several student's scores and we want to develop a C++ 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 averaged score and is finalized.
  • The averaged score is rounded off to the first decimal place when printing it.
• Use appropriate data type for each variable.
• State your name in a comment line.

This task could be broken down into the following procedures:

1. Declare and initialize two integer variables to store the number of student and the sum of score. ('int count=0' and 'int sum=0')
2. Start a loop
3. Get a student's core. (cin >> score)
4. If the core is negative, exit from the loop. (jump 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) , (be careful when 'count' is zero)
9. Print the result.
10. End
