网友回复:有人知道吗？
网友回复:TC不要搞了，就是搞明白对你也没有任何好处。好好搞VC吧
至于问题原因，为什么不单步跟踪一下呐？
网友回复:跟踪过了。就是执行到那里age输入合法后直接退出了
网友回复:这边是对的，肯定是其它地方有问题。把整个代码全贴上来。i值怎么变化的？
网友回复:检查你的checkage函数
网友回复:测试代码通过

网友回复:lz结构定义的有问题
网友回复:struct student
{
char sno[3]; /* 三字节的空间 */
char sname[20];
int sage;
float chinese_score;
float english_score;
float math_score;
float physics_score;
float chemistry_score;
}stu;
void autoget(int no,struct student s[])
{
char t[3];
if(no <10)
{
strcpy(s[no].sno,"00");
itoa(no 1,t,10);
strcat(s[no].sno,t); /* 越界了 */
}
else if(no <100)
{
strcpy(s[no].sno,"0");
itoa(no 1,t,10);
strcat(s[no].sno,t); /* 越界了 */
}
else
strcpy(s[no].sno,"100"); /* 拷贝了4字节, 越界了 */
}
网友回复:没有吧。似乎每一个都是拷贝３位的学号进去吖！
