英文:
C struct - member function accessing variable of parent struct
问题
在C++中，你可以这样做：
struct Person {int ID;char* name;void Display() {cout << "Person " << name << " ID: " << ID << endl;}};
成员函数可以访问结构体中的其他变量吗？
英文:
In C++ you could do:
class Person{public:int ID;char* name;void Display(){cout << "Person " << name << " ID: " << ID << endl;}}
Where the member function can access other variables in a class, is there anyway to do the same with a struct in C?

以下是您的C++代码的翻译部分：
class Person {public:int ID;char* name;void Display() {cout << "Person " << name << " ID: " << ID << endl;}}...Person person;...person.Display();...
以下是相似的C代码：
struct Person {int ID;char* name;}void Display(struct Person *this) {printf("Person %s ID: %d\n", this->name, this->ID);}...struct Person person;...Display(&person);...
英文:
Your C++ code:
class Person {public:int ID;char* name;void Display() {cout << "Person " << name << " ID: " << ID << endl;}}...Person person;...person.Display();...
In C there are no member functions, but similar code in C could look like this:
struct Person {int ID;char* name;}void Display(struct Person *this) {printf("Person %s ID: %d\n", this->name, this->ID);}...struct Person person;...Display(&Person);...

C不是一种面向对象的语言，但你可以做类似于这样的事情。
#include <stdio.h>#include <string.h>typedef void (*DoRunTimeChecks)();struct student{char name[20];DoRunTimeChecks func;};void Print(char name[]){printf("打印学生信息\n");printf("姓名：%s", name);}void main (){struct student s = {"shriram", Print};s.func = Print;s.func(s.name);}
英文:
c is not a object oriented language, but you can do something like this.
#include<stdio.h>#include <string.h>typedef void (*DoRunTimeChecks)();struct student{char name[20];DoRunTimeChecks func;};void Print(char name[]){printf("Printing student information\n");printf("Name: %s",name);}void main (){struct student s = {"shriram", Print};s.func = Print;s.func(s.name);}
