怎么去掉后面那个空格哇，（把printf那里的空格去掉又不行p2）源代码救救孩子吧#include<stdio.h>int main(){int a[10][10]={{1},{1},{1},{1},{1},{1},{1},{1},{1},{1}},i,j; //每行第一列初始化为1 其余初始化为0for(i=1;i<=9;i++)for(j=1;j<=9;j++){a[i][j]=a[i-1][j-1]+a[i-1][j];}for(i=0;i<=9;i++)for(j=0;j<=9;j++){if(a[i][j]!=0)printf("%d ",a[i][j]);if(j==i)printf("\n");}return 0;}
