This article mainly introduces how C++ to achieve recursion, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The programming skill in which a program calls itself is called recursion. As an algorithm, recursion is widely used in programming languages. A process or function has a method of calling itself directly or indirectly in its definition or description, which usually transforms a large and complex problem into a smaller problem similar to the original problem. The recursive strategy requires only a small number of programs to describe the repeated calculations needed in the problem-solving process, which greatly reduces the amount of code of the program. The ability of recursion lies in defining an infinite set of objects with finite statements. Generally speaking, recursion requires boundary conditions, recursive forward segments, and recursive return segments. When the boundary condition is not satisfied, the recursive forward; when the boundary condition is satisfied, the recursive return. # includeint digui (int n); int main (void) {int m; long r; printf ("Please enter the required number:"); scanf ("% d", & m); r=digui (m); printf ("% d factorial is% d\ n", m return r); return 0;} int digui (int n) {if (n) return 1 Else return n*digui;} Thank you for reading this article carefully. I hope the article "how to achieve C++ Recursion" shared by the editor will be helpful to you. At the same time, I also hope you will support us and follow the industry information channel.
