写个小程序计算猜数字问题的结果

一个教授逻辑学的教授，有三个学生，而且三个学生均非常聪明！
　　一天教授给他们出了一个题，教授在每个人脑门上贴了一张纸条并告诉他们，每个人的纸条上都写了一个正整数，且某两个数的和等于第三个！（每个人可以看见另两个数，但看不见自己的）
　　教授问第一个学生：你能猜出自己的数吗？回答：不能；
　　问第二个，不能；
　　第三个，不能；
　　再问第一个，不能；
　　第二个，不能；
　　第三个：我猜出来了，是144！
　　教授很满意的笑了。请问您能猜出另外两个人的数吗？ 请说出理由！

程序如下：

#include <stdio.h>

#include <stdlib.h>

struct number_guess
{
int num[3];
};

struct guessnumber
{
int nCount;
number_guess guess[128];
};

void savelog(char *pBuffer )
{
FILE * fp = fopen("guess.log", "a+");
if (!fp )
return ;


fwrite(pBuffer,1,strlen(pBuffer),fp);
fclose(fp);
}
guessnumber g_guessnumber[32]={0};
void calcnumber(int curnumber)
{
g_guessnumber[curnumber].nCount = g_guessnumber[curnumber-1].nCount+g_guessnumber[curnumber-2].nCount;
number_guess *pGuess =  g_guessnumber[curnumber].guess;


for (int i =0;i< g_guessnumber[curnumber-2].nCount;i++)
{
memcpy(&pGuess->num,&g_guessnumber[curnumber-2].guess[i].num,3*sizeof(int));
if (0==curnumber%3)
pGuess->num[0] = pGuess->num[1]+pGuess->num[2];
else if (1==curnumber%3)
pGuess->num[1] = pGuess->num[0]+pGuess->num[2];
else if (2==curnumber%3)
pGuess->num[2] = pGuess->num[0]+pGuess->num[1];
pGuess++;
}


for (int i =0;i< g_guessnumber[curnumber-1].nCount;i++)
{
memcpy(&pGuess->num,&g_guessnumber[curnumber-1].guess[i].num,3*sizeof(int));
if (0==curnumber%3)
pGuess->num[0] = pGuess->num[1]+pGuess->num[2];
else if (1==curnumber%3)
pGuess->num[1] = pGuess->num[0]+pGuess->num[2];
else if (2==curnumber%3)
pGuess->num[2] = pGuess->num[0]+pGuess->num[1];
pGuess++;
}
