Question

C++高手进来下! 帮个忙! 很简单的!

#include <iostream>
using namespace std;
int main()
{ int i,j;
for(i=1;i<=10;i++)
{ for(j=1;j<=20;j++)
cout<<" ";
for(j=1;j<=10-i;j++)
cout<<" ";
for(j=1;j<=2*i-1;j++)
cout<<"# ";
cout<<"\n";
}
return 0 ;
}

帮我把以上程序改成WHILE语句！！不能出现FOR语句!

谢谢了！

一楼的有没有测试啊，一楼的不能用
这个希望能帮到你

{
int i=1;
while(i<=10)
{
int j=1;
while(j<=20)
{
cout<<" ";
j++;
}
j=1;
while(j<=10-i)
{
cout<<" ";
j++;
}
j=1;
while(j<=2*i-1)
{
cout<<"#";
j++;
}
i++;
cout<<"\n";
}
return 0;

#include <iostream>
using namespace std;
int main()
{
int i=0;
while(++i<=10)
{
int j=1;
while(j++<=20)cout<<" ";
j=1;
while(j++<=10-i)cout<<" ";
j=1;
while(j++<=2*i-1)cout<<"# ";
cout<<"\n";
}
return 0 ;
