#include<iostream> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

#include<bits/stdc++.h> using namespace std; int main() { cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

谢谢，简单到不用注释*3：

print(" * ") print(" * * ") print(" * * ") print("*******")

#include <iostream> using namespace std; int main() { cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; }

模拟即可

#include<bits/stdc++.h> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

#include<iostream> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

#include<iostream> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

上集回顾：https://www.acgo.cn/problemset/422/42904?tab=explanation 这一次来讲字符串。 字符串的定义是指由若干个字符组成的东东，在C++中定义字符串的方法有两种，一种是数据类型为char（字符）的数组（见数组篇篇）而另一种为“string” string的定义： 一定要注意，要有头文件# include<string>（可以万能头） string的输入： 直接 但是，如果测试样例有空格，cin就会停止。这得用 然后输出就简单了，可以看上一集来了解。 最后AC代码：

#include <bits/stdc++.h>万能头文件 using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

十分暴力的解法

#include<iostream> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"<<endl; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<" "<<endl; cout<<" * "<<endl; cout<<" * "<<endl; cout<<"****"; return 0; }

**#include<bits/stdc++.h> using namespace std; int main(){ cout<<" * "<<endl; cout<<" * * "<<endl; cout<<" * * "<<endl; cout<<"*******"<<endl; }**
