请高手指点这段代码有误逻辑错误：
# include <stdio.h>
# include <string.h>

struct People
{
    int age;
    char color;
    char name[50];
};

void inPut(struct People *);
void outPut(struct People *);

int main(void)
{
    struct People * p;

    inPut(p);
    outPut(p);

    printf("%d\n",(*p).age);

    return 0;
}

void inPut(struct People * pe)
{
    pe->age = 12;
    pe->color = 'b';
    strcpy(pe->name,"奥多姆");
}

void outPut(struct People * pe)
{
    printf("%d %c %s\n",pe->age,pe->color,pe->name);
}


/*
总结：该程序在VC6.0中运行时报错
*/

给你改好了，自己好好研究下

#include <stdio.h>
#include <string.h>
#include <stdlib.h>//<---------调用malloc函数用的头文件

struct People
{
    int age;
    char color;
    char name[50];
};

void inPut(struct People **);// <------注意形参用指向指针的指针
void outPut(struct People *);

int main(void)
{
    struct People * p;

    inPut(&p);       //<--注意
    outPut(p);
    printf("%d\n",p->age);//<------结构指针调用成员应该这样写
    free(p);
    return 0;
}

void inPut(struct People ** pe)//<--注意
{
    *pe = (struct People *)malloc(sizeof(struct People));//<---------给*pe开辟动态空间，好赋值
    (*pe)->age = 12;                                      //<--注意
    (*pe)->color = 'b';                                   //<--注意
    strcpy((*pe)->name,"奥多姆");
}

void outPut(struct People * pe)
{
    printf("%d %c %s\n",pe->age,pe->color,pe->name);
}

谢谢，我自己也找到了一个修改方法，一起研究一下：# include <stdio.h>
# include <string.h>

struct People
{
    int age;
    char color;
    char name[50];
};

void inPut(struct People *);
void outPut(struct People *);

int main(void)
{
    struct People p;
    //若声明为：struct People * p;必须要对P初始化赋值
   
    inPut(&p);
    outPut(&p);

    return 0;
}

void inPut(struct People * pe)
{
    pe->age = 12;
    pe->color = 'b';
    strcpy(pe->name,"奥多姆");
}

void outPut(struct People * pe)
{
    printf("%d %c %s\n",pe->age,pe->color,pe->name);
}

这是形参和实参的区别，你后面改的跟我的意思是一样的，函数调用的是实参的地址，所以实参值就改变了
