结构体

  struct 结构体名{} 变量名;

结构体变量：

        struct person{

                char *name;

                int age;

                float score;

        } student;

成员的获取和赋值

        //Members of the acquisition and assignment

        student.name="taoshihan";

        student.age=30;

        student.score=100;

        printf("name=%s \n",student.name);

C语言结构体数组

        struct stu{

                char *name;

                int age;

                float score;

        } classes[5];

遍历结构体数组

        struct people{

                char *name;

                int age;

                float score;

        } d[]={

                {"taoshihan",20,100},

                {"lisi",30,90}

        };

        int len=sizeof(d)/sizeof(d[0]);

        printf("d length=%d \n",len);

        for(int i=0;i<len;i++){

                printf("loop...%s,%d,%.1f \n",d[i].name,d[i].age,d[i].score);

        }

C语言结构体和指针

  struct 结构体名 *变量名;

        struct person1{

                char *name;

                int age;

                float score;

        }
