**题目内容：**

任意输入英文的星期几，通过查找如图所示的星期表，输出其对应的数字，若查到表尾，仍未找到，则输出错误提示信息。![6f3496b75b514d701eff77a0eef354b5.png][]

提示：用一个二维字符数组weekDay来存放如图所示的星期表的内容（字符串）。输入待查找的字符串，然后在星期表中顺序查找与输入字符串相匹配的字符串。找到的字符串在星期表数组中的第一维下标（行号）即为题目所求。

程序运行结果示例1：

Please enter a string:

Friday↙

Friday is 5

程序运行结果示例2：

Please enter a string:

Fruday↙

Not found!

#include<stdio.h>

        /* 存储用户键入的字符串 */
        char Input[10];
        printf("Please enter a string:\n");
        /* 键入待查找信息 */
        gets(Input);

        }
        else

        }
        /* */
        return 0;
    }
    /* */
    short MatchWeekDay(char (*p)[10], char *q)
    {
        short i, j;
        short flag = 0;
        for(i = 0; i < 7; i ++)
        {
            if(strcmp(p[i], q) == 0)
            {
                /* 两个字符串相同 */
                return i;
            }
        }
        return -1;
    }
