main函数中的printf()中漏了一个% 代码修改如下：

#include <conio.h>
#include <string.h>

#include <malloc.h> 
/*将数字转换成整数*/ 
int ChangeStrToInt (char str[])

    for(; * str!= '\0'; str++)
    {
        /*将字符表示的数字转换成对应的整数数字并拼接成对应的整数 */ 
        result = result * 10 + ( *str - 48); //修改
    }
    return result; 
} 
/*从字符串中取出对应的子串 */ 
/* 如：字符串"ABCD",取出第二个字符开始到第4个字符结束，得到字符串"BCD" */ 
char * GetSubString(char * str, int begin, int end)
{
    char * result;
    int i;
    /* 为局部变量申请内存 */
    result = (char* )malloc(end -begin + 2); /* 用空字符填充字符串 */
    for(i = 0; i<end -begin + 2;i++) result[i] = 0;
    /* 取子串 */
    for(i = begin - 1;i<= end - 1;i++) 
        result[i - begin + 1] = str[i]; 
    return result;
}
void GetIDCodeInfo(char * idCode,int currentYear,int * year, int * month, int * day, int * age, int * gender)
{ /*GetSubString(idCode,7,10)是函数调用语句 */
