75 结构体嵌套指针 上01 结构体嵌套指针 为该指针成员malloc结构体变量的地址和它的第一个成员的地址相等；psn的指针成员psn.name存储着一块指向地址为00995B30堆空间的内存。#include <stdlib.h>#include <stdio.h>typedef struct persons{ char* name; int age;}persons;void main() { persons psn; psn.name = (

74 结构体动态数组01 栈区 堆区 结构体数组#include <stdlib.h>#include <stdio.h>typedef struct persons{ char name[21]; int age;}persons;void main() { persons psn[3] = { {"何无忌",33}, {"刘毅",34},{"檀凭之",45} }; for (int i = 0; i < 3; i++) { printf("%

1 同一结构体的变量互相赋值#include <stdlib.h>#include <stdio.h>typedef struct persons{ char name[21]; int age;}persons;void main() { persons psn = {"桓修",46}; persons psn2=psn; printf("%s\t%d\n", psn.name, psn.age); printf("%s\t%d\n", psn2.nam

71 结构体初始化为什么UE4原码喜欢用->，因为.的话error或乱码，又不用strcpy01 结构体的成员列表赋值为字符串常量时#include <stdlib.h>#include <stdio.h>typedef struct persons{ char name[21]; int age;}persons;void main() { persons psn; //psn.name = "司马元显";//error //psn.name[

70 结构体定义01 四种结构体定义#include <stdlib.h>#include <stdio.h>//1struct persons01{ char name[21]; int age;};//2struct persons02{ char name[21]; int age;}psn02 = {"谢琰",46};//3struct{ char name[21]; int age;}psn03 = {"鲍陋",67};
