Print out the Yang Hui Triangle, which can be used as an entrance to thought according to one of its properties: the number of J in line I is equal to the j-1 bit of line i-1 plus the number of j digits, i.e. a[i][j]=a[i-1][j-1]+a[i-1][j].

------------------------------------------------------------------------------------------------------

The C language code is as follows:

# include <stdio.h># include <stdlib.h># include <string.h>int  main () {     int arr[10][10]={{1}};     int  line, row,space;     for  (line = 0; line < 10;  line++)      {          for   (row = 0; row <=line; row++)            {               if   (LINE&NBSP;&LT;&NBSP;2)                              //first two behaviors 1                {                     arr[line][row] = arr[0][0];                }                else if  (row == 0 | |  row == line)         //element is 1                {                     arr[line][row] = arr[0 ][0];               }                else                                        //Use property Assignment                 {                     arr[line][row] =  (arr[line  - 1][row - 1] + arr[line - 1][row]);                }            }     }           for  (line = 0; line < 10; line++)                //Output      {           for  (row = 0; row <= line; row++)           {                printf ("%3d ",  arr[line][row]);           }      printf ("\ n");  }      system (" Pause ");      return 0;}

little knowledge of dry goods: 1. Right-shift operations with signed values are not portable.

2. The value of the shift operation cannot be negative.

3. The order of evaluation of an expression is partly determined by the precedence and binding of the operators it contains (priority

Greater than the binding); Similarly, the operands of some expressions may need to be converted to other types during evaluation,

("Implicit type Conversions" and "Arithmetic Conversions").
