跨函数使用内存

#include<stdio.h>
#include<malloc.h>
struct Student{
  int sid;
  int age;
}
 struct Student* CreateStudent(void);
void ShowStudent(strucent Student*) 
int main(void)
{
  strucent Studetn* ps;
  ps = CreateStudetn();
  ShowStudent(ps);
  return 0;
}
void ShowStudent(strucent Student* pst)
{
  printf("%d %d \n",pst->sid,pst->age);

}
strucent Student* CreateStudent(void)
{
  struct Student * p = (struct Student*)malloc(sizeof(struct Student));
  p->sid =1001;
  p-age = 18;
   return p;
}
