Answer 4

#include <stdio.h>int main() { int i,j; int a[10][10]; printf("\n"); for(i=0;i<10;i++) {  a[i][0]=1;  a[i][i]=1; } for(i=2;i<10;i++)  for(j=1;j<i;j++)   a[i][j]=a[i-1][j-1]+a[i-1][j]; for(i=0;i<10;i++) {  for(j=0;j<=i;j++)   printf("%5d",a[i][j]);  printf("\n"); } return 0;}  再来个java语言的int[] triangle=null; int[] tmp=null;  for (int i=0;i<10;i++){      if(i==0){          tmp = new int[1];          tmp[0]=1;      } else if (i==1){          tmp = new int[3];          tmp[0] = 1;         tmp[1] = 2;          tmp[2] = 1;      } else {         tmp=new int [i+2];          tmp[0]=1;          for(int j=1;j<i+1;j++){              tmp[j]=triangle[j-1]+triangle[j];          }      tmp[tmp.length-1]=1;      }      triangle=tmp;      for(int j=0;j<triangle.length;j++){          System.out.print(tmp[j]);          System.out.print(" ");      }      System.out.println();  }
