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

题目分析：

本题只需要用到最基本的输入输出，故而只需要使用 cstdio 库中的 scanf 和 printf 两个函数即可。

代码如下：

#include<cstdio>
int main(){
	char a;
	scanf("%c",&a);
	printf("  %c\n %c%c%c\n%c%c%c%c%c\n %c%c%c\n  %c",a,a,a,a,a,a,a,a,a,a,a,a,a);
	return 0;
}
