This article mainly explains "A brief introduction to the exception handling mechanism of C++". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn the "brief introduction of C++ exception handling mechanism".

The main results are as follows: (1) the exception handling mechanism of C makes it unnecessary for exception throwing and exception handling to be in the same function, so that the underlying function can focus on solving specific problems without paying too much attention to exception handling. The upper caller can design the handling of different types of exceptions in an appropriate location.

(2) the exception is specially aimed at a series of errors in abstract programming, and the function mechanism cannot be used in C, because the essence of the stack structure is first in, then out, and cannot jump. However, the characteristic of error handling is that when you encounter an error message, you want to go to several levels to try again.

At this point, I believe that you have a deeper understanding of the "brief introduction of C++ exception handling mechanism", you might as well come to the actual operation! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
