编写自己的头文件

1、头文件TestCpp.h

#ifndef TESTCPP_H
#define TESTCPP_H
struct TestCpp{
    std::string name;
    unsigned int id;
};
#endif

2、主函数testTestCpp.cpp

#include <iostream>
#include "TestCpp.h"
int main()
{
    TestCpp t1;
    t1.name = "xiaoming";
    t1.id = 20190203;    
    std::cout << "name: " << t1.name << std::endl;
    std::cout << "id: " << t1.id << std::endl;
    return 0;
}
