enum loop{NO, YES};
enum loop okloop = YES;

这里用了 一个枚举变量。
int main(void)
{
/*
for (i = 0; i < lim-1 && (c=getchar()) != '\n' && c != EOF; ++i)
s[i] = c;
*/
int i = 0,
lim = MAX_STRING_LENGTH,
c;
char s[MAX_STRING_LENGTH];
while (i < (lim - 1))
{
c = getchar();
if (c == EOF)
break;
else if (c == '\n')
break;
s[i++] = c;
}
s[i] = '\0'; /* terminate the string */
return 0;
}
