Question

我是初学者，我必须打印这封信＆＃34; N＆＃34;超出了＃。到目前为止我只能打印| \，所以我仍然错过了最后一条腿＃39; 我实际上并不知道我到目前为止如何......如果有人可以帮助我或解释！这是我的代码：

#include <iostream>
using namespace std;

int main()
{

    int i, j;

    for (i = 1; i <= 9; i++)
    {
        cout << "#";
        for (j = 1; j <= 12; j++)
        {
            if (i == j)
            {
                cout << "#";
            }
            else
            {
                cout << " ";
            }
        }

        cout << endl;
    }

    return 0;
}

Answer 1

for (i = 1; i <= 9; i++)  //prints one line at a time
{
    cout << "#";
    for (j = 1; j <= 9; j++)
    {
        if (i == j)
        {
            cout << "#";  //Diagonal part
        }
        else
        {
            cout << " ";  
        }
    }
    cout << "#";  // <<< You missed this

    cout << endl;
}

更优雅（仅使用一个for - 循环）：

for (i = 1; i <= 9; i++)
{
    string s = "#";
    s.append(i-1, ' ' );
    s +='#';
    s.append(9-i, ' ' );
    s +='#';
    cout << s << endl;
}

Answer 2

我会选择＆＃34; Cheeting＆＃34;打印精确的东西而不用循环修复。

cout << "##      #" << endl
cout << "# #     #" << endl
cout << "#  #    #" << endl
cout << "#   #   #" << endl
cout << "#    #  #" << endl
cout << "#     # #" << endl
cout << "#      ##" << endl

很容易就像馅饼一样。

Answer 3

    for(int y=0; y<9;y++){

    for(int i=0; i<9; i++){

    if((i==8&&y==0) or(i==8&&y==8) ){std::cout<<" ";}

    if(i==0 or i==8){std::cout<<"#";}else{std::cout<<" ";};

    if(i>0 && i<8){if(i==y){std::cout<<"#";std::cout<<" ";}else{std::cout<<" ";};};

    };std::cout<<"\n";};
