郝斌数据结构　　10　跨函数使用内存讲解及其示例

#include<stdio.h>
#include<malloc.h>

struct Student
{
int sid;
int age;
};

struct Student * CreateStudent(void)
{
struct Student *p = (struct Student *)malloc(sizeof(struct Student));
p->sid = 10;
p->age = 15;
return p;
}

void ShowStudent(struct Student *ps)
{
printf("id = %d   age = %d\n",ps->sid,ps->age);
}
int main(void)
{
struct Student *ps;
ps = CreateStudent();
ShowStudent(ps);
free(ps);
return 0;
}
