Running result:

Experience:

It is too complicated to compile this program under the course. It involves many things. But the teacher often told me that programming is easier and easier. Simple and seemingly complex problems are essential skills.

Knowledge Point summary:

I learned to call the SQRT function. I am thinking, if the SQRT function is a negative value, do I need to adjust it to a positive value?
