Question

C语言的程序出现了错误 就高手指点 谢谢

#include;
#include;
struct Student
{
int sid;
int age;

}
struct Student * CreateStudent(void);
void ShowStudent(struct Student *);
int main(void)
{
struct Student *ps;
ps=CreateStudent();
ShowStudent(ps);

return 0;

}
void ShowStudent(struct Student *pst)
{
printf("%d %d\n",pst->sid ,pst->age);
}

struct Student * CreateStudent(void)
{
struct Student *p=(struct Student *)malloc(sizeof(struct Student));
p->sid=99;
p->age=88;
return p;

}

这段代码调试出现了以下错误 求高手解

执行 cl.exe 时出错.

memory_2.obj - 1 error(s), 0 warning(s)
头文件 为
#include <stdio.h>;
#include <malloc.h>;

Answer 1

#include <stdio.h>    //这行有问题

#include <malloc.h>

struct Student
{
 int sid;
 int age;
 
};   //这行有问题
struct Student * CreateStudent(void);
void ShowStudent(struct Student *);
int main(void)
{
 struct Student *ps;
 ps=CreateStudent();
 ShowStudent(ps);

 return 0;

}
void ShowStudent(struct Student *pst)
{
 printf("%d %d\n",pst->sid ,pst->age);
}

struct Student * CreateStudent(void)
{
 struct Student *p=(struct Student *)malloc(sizeof(struct Student));
 p->sid=99;
 p->age=88;
 return p;

}

Answer 2

//include不用加分号
#include <stdio.h>
#include <malloc.h>
struct Student
{
int sid;
int age;

} ; //结构体定义要有分号
