下面程序中分配内存空间函数malloc的使用为什么会报错?
#include <stdio.h>
main()
{
    struct stu
    {
      int num;
      char *name;
      char sex;
      float score;
    }  *ps;
    ps=(struct stu*)malloc(sizeof(struct stu));
    ps->num=102;
    ps->name="Zhang ping";
    ps->sex='M';
    ps->score=62.5;
    printf("Number=%d\nName=%s\n",ps->num,ps->name);
    printf("Sex=%c\nScore=%f\n",ps->sex,ps->score);
    free(ps);
}

使用malloc要加#include<malloc.h>或#include<stdlib.h>函数头

楼上正解

#include <stdio.h>
#include<malloc.h>
main()
{
    struct stu
    {
      int num;
      char *name;
      char sex;
      float score;
    }  *ps;
    ps=(struct stu*)malloc(sizeof(struct stu));
    ps->num=102;
    ps->name="Zhang ping";
    ps->sex='M';
    ps->score=62.5;
    printf("Number=%d\nName=%s\n",ps->num,ps->name);
    printf("Sex=%c\nScore=%f\n",ps->sex,ps->score);
    free(ps);
}

同意2楼

#include<stdlib.h>
谭浩强C 第三版里在讲malloc时提过的

应该使用stdlib.h或者string.h

对于malloc.h是废弃的头文件
