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
#include
#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!n");
else printf("%dn", n);
return 0;
}
输入样例1:
Tuesday
Tuesday
结尾无空行
输出样例1:
2
结尾无空行
输入样例2:
today
输出样例2:
wrong input!
int getindex(char *s)
{
int week;
char day[7][10] = { "Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday" };
for (week = 0; week <= 6; week++)
{
if (strcmp(s, day[week]) == 0) break;
}
if (week == 7) week = -1;
return week;
}
wrong input!
int getindex(char *s)
{
int week;
char day[7][10] = { "Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday" };
for (week = 0; week <= 6; week++)
{
if (strcmp(s, day[week]) == 0) break;
}
if (week == 7) week = -1;
return week;
}
