一道简单的ACM程序题

Description
Stan and Ollie are playing a guessing game. Stan thinks of a number between 1 and 10 and Ollie guesses what the number might be. After each guess, Stan indicates whether Ollie's guess is too high, too low, or right on. After playing several rounds, Ollie has become suspicious that Stan cheats; that is, that he changes the number between Ollie's guesses. To prepare his case against Stan, Ollie has recorded a transcript of several games. You are to determine whether or not each transcript proves that Stan is cheating.

Input
Standard input consists of several transcripts. Each transcript consists of a number of paired guesses and responses. A guess is a line containing single integer between 1 and 10, and a response is a line containing "too high", "too low", or "right on". Each game ends with "right on". A line containing 0 follows the last transcript.

Output
For each game, output a line "Stan is dishonest" if Stan's responses are inconsistent with the final guess and response. Otherwise, print "Stan may be honest".

Sample Input
10
too high
3
too low
4
too high
2
right on
5
too low
7
too high
6
right on
0

Sample Output
Stan is dishonest
Stan may be honest

我的第一个代码在网上提示说是 wrong answer，，如下

#include "stdio.h"
#include "string.h"

void main()
{ char b[100][100];
int i,e,c[10],j=0,d;
scanf("%d",&e);
while(e!=0)
{ d=0;
c[j]=e;getchar();
gets(b[j]);
do{j++;
scanf("%d",&c[j]);getchar();
gets(b[j]);
}while(strcmp(b[j],"right on")!=0);
for(i=0;i<j;i++)
if(c[i]<c[j]&&strcmp(b[i],"too high")==0||
c[i]>c[j]&&strcmp(b[i],"too low")==0||c[j]<1||c[j]>10)
{d=1;break;}
j=0;
if(d==1)printf("Stan is dishonest\n");
else printf("Stan may be honest\n");
scanf("%d",&e);
}

}

第二个代码能在网上通过，如下

#include "stdio.h"
#include "string.h"

void main()
{ char b[100][100];
int i,e,c[100],j=0,min,max;
scanf("%d",&e);
while(e!=0)
{ min=1;max=10;
c[j]=e;getchar();
gets(b[j]);
do{j++;
scanf("%d",&c[j]);getchar();
gets(b[j]);
}while(strcmp(b[j],"right on")!=0);
for(i=0;i<j;i++)
if(strcmp(b[i],"too high")==0) max=c[i]<max?c[i]:max;
else if(strcmp(b[i],"too low")==0) min=c[i]>min?c[i]:min;

if(c[j]<max&&c[j]>min) printf("Stan may be honest\n");
else printf("Stan is dishonest\n");
scanf("%d",&e); j=0;
}

}

但是我认为这两个代码本质上都是一样的，我极度不明为什么会出现不同的结果，希望有空的各位能帮手看一下，还有如果有耐性看别人的代码而且有空指导我的其它ACM题目的，你要多少分我都可以给你（我还有其它号），有心人留下QQ，，以后联系，，感激不尽呀~~~
再说一下，我是大一的，菜鸟都可以指导我的，呵呵~~~

Answer 1

if(c[i]<c[j]&&strcmp(b[i],"too high")==0||
c[i]>c[j]&&strcmp(b[i],"too low")==0||c[j]<1||c[j]>10)
中c[i]<c[j]改成c[i]<=c[j];c[i]>c[j]改成c[i]>=c[j],应该不用我解释了吧。
你很有发展潜力，好好努力吧
