Quickly uses the C ++ exception capture mechanism (several lines of code in a program)

Sorted out classic triangles circulating on the InternetCode, Added content that you understand.

The final goal is to first use try catch blocks in C ++. Then I thoroughly understood the error mechanism of C ++.

Here, I would like to share with you what is wrong with writing, or what is wrong with writing,

You are welcome to raise any suggestions for better improvement.

I would like to be grateful here.
