The compilers are all vs2013 under windows
When in the same file: first acquaintance
Create file main.cpp
# include<iostream>
//class people //定义一个类
//{
//public: // 公有
// void sayhello(){
// std::cout << "Hello World\n";
//}
//};
int main(int argc, const char * argv[])
{
people *p = new people();
p->sayhello(); //通过指针p访问到成员方法
delete p; //释放内存空间
system("pause");
return 0;
}Remove the comments from the above file and you can successfully run and output Hello World.
After ok, we continue to create a c++ class file named people.
Define a class in people.h:
#pragma once
class people
{
public:
void sayhello();
};Implement this class in people.cpp:
# include<iostream>
#include "people.h"
using namespace std;
void people::sayhello()
{
cout << "Hello World\n";
}
