本题要求实现函数,可以根据下表查找到星期,返回对应的序号。
序号 | 星期 |
---|---|
0 | Sunday |
1 | Monday |
2 | Tuesday |
3 | Wednesday |
4 | Thursday |
5 | Friday |
6 | Saturday |
函数接口定义:
int getindex( char *s );
函数getindex
应返回字符串s
序号。如果传入的参数s
不是一个代表星期的字符串,则返回-1。
裁判测试程序样例:
#include <stdio.h>
#include <string.h>#define MAXS 80int getindex( char *s );int main()
{int n;char s[MAXS];scanf("%s", s);n = getindex(s);if ( n==-1 ) printf("wrong input!\n");else printf("%d\n", n);return 0;
}/* 你的代码将被嵌在这里 */
输入样例1:
Tuesday
输出样例1:
2
输入样例2:
today
输出样例2:
wrong input!
#include<string.h>
int getindex( char *s ){char date[7][10]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};int i;for(i=0;i<7;i++){char *a=date[i];if(strcmp(a,s)==0)return i;}return -1;
}
