這是一次慘痛的經歷，三個人照著一個連知識點也沒有聽過的題做了三個小時，把這個水題給放過去了。哇呀呀，難受的一批啊。 題目描述：就是按著放大的倍數放大數字 程式碼如下：

#include<iostream>
#include<cstdio>
#include<cstring>
using namespace std;

char a[11];
int k;

int main()
{
	while(cin>>k>>a)
	{
		if(k==0||!strcmp(a,"0")) break;
		int len=strlen(a);
		for(int i=0;i<2*k+3;i++)
		{
			for(int j=0;j<len;j++)
			{
				if(i==0)
				{
					if(a[j]=='0'||a[j]=='2'||a[j]=='3'||a[j]=='5'||a[j]=='6'||a[j]=='7'||a[j]=='8'||a[j]=='9')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0) cout<<" ";
							else if(m!=k+1) cout<<"-";
						} 
						cout<<"  ";
					}
					else if(a[j]=='4')
					{
						for(int m=0;m<k+2;m++) cout<<" ";
						cout<<" ";
					}
					else cout<<"  ";
				}
				else if(i>=1&&i<=k)
				{
					if(a[j]=='0'||a[j]=='8'||a[j]=='9'||a[j]=='4')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0||m==k+1) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
					else if(a[j]=='2'||a[j]=='3'||a[j]=='7')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==k+1) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
					else if(a[j]=='5'||a[j]=='6')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
					else if(a[j]=='1')
					{
						cout<<"|";
						cout<<" ";
					}
				}
				else if(i==k+1)
				{
					if(a[j]=='1')
					{
						cout<<" ";
						cout<<" ";
					}
					else if(a[j]=='0'||a[j]=='7')
					{
						for(int m=0;m<k+2;m++)
						{
							cout<<" ";
						}
						cout<<" ";
					}
					else 
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0||m==k+1) cout<<" ";
							else cout<<"-";
						}
						cout<<" ";
					}
				}
				else if(i>k+1&&i<2*k+2)
				{
					if(a[j]=='1')
					{
						cout<<"|";
						cout<<" ";
					}
					else if(a[j]=='2')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
					else if(a[j]=='3'||a[j]=='4'||a[j]=='5'||a[j]=='7'||a[j]=='9')
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==k+1) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
					else 
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0||m==k+1) cout<<"|";
							else cout<<" ";
						}
						cout<<" ";
					}
				}
				else if(i==2*k+2)
				{
					if(a[j]=='1')
					{
						cout<<" ";
						cout<<" ";
					}
					else if(a[j]=='7'||a[j]=='4')
					{
						for(int m=0;m<k+2;m++)
						cout<<" ";
						cout<<" ";
					}
					else 
					{
						for(int m=0;m<k+2;m++)
						{
							if(m==0||m==k+1) cout<<" ";
							else cout<<"-";
						}
						cout<<" ";
					}
				}
			}
			cout<<endl;
		}
		cout<<endl;
	}
}
```就是從第一層開始一層一層的往下弄，找尋各個數的相同特點。仔細寫寫就好了。
