題意：輸入兩個數作為長方形的長和高，按照給定的樣例輸出一個長方形。

解題思路：

1、第一行和最後一行為一類，首項和尾項為“+”，其餘為“-”；

2、其餘各行為一類，首項和尾項為“+”，其餘為空格。

源代碼為：

#include<iostream>
using namespace std;
int main()
{
	int n, m;
	while (cin >> n >> m)
	{
		for (int i = 1; i <= m+2; i++)
		{
			if (i == 1 || i == m+2)
			{
				for (int j = 1; j <= n + 2; j++)
				{
					if (j == 1)
						cout << "+";
					else if (j == (n + 2))
						cout << "+" << endl;
					else
						cout << "-";
				}
			}
			else
				for (int j = 1; j <= n+2; j++)
				{
					if (j == 1)
						cout << "|";
					else if (j == n + 2)
						cout << "|" << endl;
					else
						cout << " ";
				}
			
		}
		cout << endl;
	}
	return 0;
}
