6-1 查找星期 (15 分)
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 80
int getindex( char *s );
int main()
{
int n;
char s[MAXS];
scanf("%s", s);
n = getindex(s);
if ( n==-1 ) printf("wrong input!
");
else printf("%d
", 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!
答案:
int getindex( char *s )
{
char *a[10]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
int k;
for(k=0;k<7;k++){
if(strcmp(s,a[k])==0)
return k;
}
return -1;
}
