Question

C++中.h和.cpp

以下是.h,.cpp和主程序三段,应该怎么关联

//NameFunction.h
#include<string>
#include<vector>
using namespace std;
//======================================
void FillVectors(vector<string> &name,vector<string> $origins);
string AskUserForName();
bool SearchForName(vector<string> &names,vector<string> &origins,string &userName,string &userOrigin);

//NameFunctions.cpp
#include<iostream>
#include<string>
#include<vector>
using namespace std;
//======================================================================================================
bool SearchForName(vector<string> &names,vector<string> &origins,string &userName,string &userOrigin)
{
for(int index=0;index<names.size();index++)
{
if(userName==names.at(index)){userOrigin=origins.at(index);return true;}
}
return false;
}
//=======================================================================================================
void FillVectors(vector<string> &name,vector<string> &origins)
{
name.push_back("Barbara");
origins.push_back("greek,meaning stranger");

name.push_back("Kelly");
origins.push_back("celtic,meaning warrior or defender");
}
//=======================================================================================================
string AskUserForName()
{
string userName;
cout<<"Please enter a women's name,such as Kelly;"<<endl;
cin>>userName;
return userName;
}
//=======================================================================================================

//============================================================================
#include<iostream>
#include<string>
#include<vector>
using namespace std;

#include "NameFunctions.h"

//=========================================================
int main()
{
cout<<"Welcome to C++ Name Search Program"<<endl;
vector<string> names,origins;
FillVectors(names,origins);//用函数对定义的两个vector对象赋值;

string userName,userOrigin,answer="yes";
bool Found;//判断是否找到;
for(;answer=="yes"||answer=="Yes";)
{
userName=AskUserForName();
Found=SearchForName(names,origins,userName,userOrigin);
if(Found)
{
cout<<"Here is your name: "<<userName<<endl;
cout<<"Origin: "<<userOrigin<<endl;
}
else{cout<<" Sorry "<<userName<<" isn't in our vector."<<endl;}
cout<<"Do you have another name? yes/no ";
cin>>answer;
}
return 0;
}

Answer 1

你先建一个控制台的工程。用vc 6.0或者 vs
选空工程

然后新建一个c/C++ Head file 名字叫NameFunction.h
接着建一个 c ++ source file 名字叫做NameFunctions.cpp
接着再建一个 c ++ source file 名字随便起。。自己定
就可以了。。。
记住这三个文件要在同一个工程里。

Answer 2

h.cpp
是C++文件
.h.c
c语言文件
输入输出的头文件不同，文件扩展名不同
C++是#include<iostream.h>
或#include<iostream>
using
namespace
std;
C语言的头文件是#include<stdio.h>
……
其实在很多情况下都是兼容的，C语言和C++可以混合编程
