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.
