这样为什么错~空白的地方用空格不行吗~~?#include<iostream>
using namespace std;
int main()
{
char tri[21][21]={' '};
int n;
char s;
cin>>n>>s;
char x=s;
for(int j=1;j<=n;j++)
for(int i=1;i<=j;i++){
tri[i][j]=x;
x++;
if(x>'9')x='1';
}
for(int i=1;i<=n;i++){
for(int j=1;j<=n;j++){
cout<<tri[i][j];
if(j!=n)cout<<' ';
}
if(i!=n)cout<<endl;
}
}
