Preface

OK, Today, let's talk about a simple code ： Yang hui triangle .

The main new element is that we can customize the number of rows of Yang Hui triangle , such , It makes the program a little interesting , It becomes a medium-level code .

Three steps to learn code ：

1. Read the code ;

2. Modify the code ;

3. Write your own code

Code finished steps ：

1. Determine the function ;

2. Draw flow chart ;

3. Write code ;

4. debugging ;

5. test ;

6. finished product

OK, Write code , A teacher said , The code is not written , It is debugged , Deeply think the same , Share with you , Slowly realize in the process of writing code by yourself .

One 、 Code

I put the analysis of the code in the comments , You can better analyze the code by yourself , Next is the code ：

#include<stdio.h>                // The header file 
int main()
