题目：
Problem Description
Give you the width and height of the rectangle,darw it.
 

Input
Input contains a number of test cases.For each case ,there are two numbers n and m (0 < n,m < 75)indicate the width and height of the rectangle.Iuput ends of EOF.
 

Output
For each case,you should draw a rectangle with the width and height giving in the input.
after each case, you should a blank line.
 

Sample Input
3 2
 

Sample Output

这个题格式很搞人  注意最后一句after each case, you should a blank line

#include <stdio.h>

int main()
{
    int i,j,k;
    int w,h;
    while(EOF != scanf("%d%d",&w,&h))
    {
        char a[77][77] = {0};
        a[0][0] = '+';a[0][w+1] = '+';
        a[h+1][0] = '+';a[h+1][w+1] = '+';
        for(i = 1;i<=w;i++)
            a[0][i] = a[h+1][i] = '-';
        for(i = 1;i<=h;i++)
            a[i][0] = a[i][w+1] = '|';
        for(i = 0;i<=h+1;i++)
        {
            for(j = 0;j<=w+1;j++)
                if(a[i][j])
                    putchar(a[i][j]);
                else
                    putchar(' ');
            printf("\n");
        }
        printf("\n");
    }   
    return 0;
}
