用多个文件编程 [英] Program with multiple files

问题描述

你好，

我写了这样一个程序，我想将函数sudeti和atimti移动到不同的cpp文件中。你能帮助我吗？

：

Hello,
I wrote such a program and I want to move functions "sudeti" and "atimti" to different cpp file. Can you help me?
:

#include <iostream>
int i,mas[5],n,suma,skirtumas,test;
char kodas;
int sudeti(int i, int mas[5], int n, int suma);
int atimti(int i, int mas[5], int n, int suma);

int sudeti()
{
    using namespace std;
    for (i = 0; i < n; i++)
    {
        cout << "Iveskite " << i+1 << "-aji skaiciu: " << endl;
        cin >> mas[i];
        suma = suma + mas[i];
    }
    cout << "******************************" << endl;
    return suma;
}
int atimti()
{
    using namespace std;
    for (i = 0; i < n; i++)
    {
        cout << "Iveskite " << i+1 << "-aji skaiciu: " << endl;
        cin >> mas[i];
    }
    cout << "******************************" << endl;
    skirtumas = mas[0] - mas[1] - mas[2] - mas[3] - mas[4];
    return skirtumas;
}
int main()
{
    using namespace std;

    cout << "Kiek skaiciu naudosite?" << endl;
    cin >> n;
    cout << "******************************" << endl;
    cout << "Iveskite norimo veiksmo koda:" << endl;
    cin >> kodas;
    cout << "******************************" << endl;
        switch (kodas)
    {
        case '+' :
         {
              cout << "Suma yra lygi: "<< sudeti();
         }
        break;
        case '-' :
        {
            cout << "Skirtumas yra lygus: " << atimti();
        }
        break;
        default : cout << "Tokio veiksmo nera" << endl;
    }

}

推荐答案

创建新的文本文件（扩展名.cpp）并复制/将功能代码粘贴到它们中。



为原型创建一个头文件（扩展名为.h）（将2个原型复制到该文件中）。



#include 原始文件中的头文件（ main 是）。



在你的新cpp文件中添加所有必要的#include。



什么平台是你用的？视觉工作室 ？ gcc / g ++ Linux？其他东西。



您必须将新文件添加到当前项目中（在Visual Studio中，将文件添加到项目中）。

在使用gcc / g ++的linux上你可能需要创建或更新你的makefile（如果你使用的是IDE，我不知道这是怎么回事）。



祝你好运。



Max。

Create new text file (extension .cpp) and copy/paste the function code into them.

Create a header file (extension .h) for the prototype (copy the 2 prototypes into that file).

#include that header file in your original file ( where the main is).

Add all the necessary #include in your new cpp file.

What platform are you using ? Visual Studio ? gcc/g++ Linux ? something else.

You will have to add your new file to either the current project (in Visual Studio, add the file to the project).
On linux with gcc/g++ you might have to create or update your makefile (don''t know how this work if you are using an IDE).

Good luck.

你需要移动这些功能，如下所示：

1.主标题文件： program.h

You need to move the functions, something like the following:
1. Main header file : program.h

#include <iostream>

int sudeti(int mas[5], int n, int suma);
int atimti(int mas[5], int n, int suma);
 
using namespace std;

2. sudeti.cpp

2. sudeti.cpp

#include "program.h"
 
int sudeti(int mas[5], int n, int suma)
{
    int i;

    for (i = 0; i < n; i++)
    {
        cout << "Iveskite " << i+1 << "-aji skaiciu: " << endl;
        cin >> mas[i];
        suma = suma + mas[i];
    }
    cout << "******************************" << endl;
    return suma;
}

3. atimti.cpp

3. atimti.cpp

#include "program.h"
 
int atimti(int mas[5], int n, int suma)
{
    int i; 
    int skirtumas; 

    for (i = 0; i < n; i++)
    {
        cout << "Iveskite " << i+1 << "-aji skaiciu: " << endl;
        cin >> mas[i];
    }
    cout << "******************************" << endl;
    skirtumas = mas[0] - mas[1] - mas[2] - mas[3] - mas[4];
    return skirtumas;
}

4. main.cpp

4. main.cpp

#include "program.h"

int main()
{
    char kodas;
    int mas[5];
    int n;
    int suma;

    cout << "Kiek skaiciu naudosite?" << endl;
    cin >> n;
    cout << "******************************" << endl;
    cout << "Iveskite norimo veiksmo koda:" << endl;
    cin >> kodas;
    cout << "******************************" << endl;
        switch (kodas)
    {
        case '+' :
         {
              cout << "Suma yra lygi: "<< sudeti(mas, n, suma);
         }
        break;
        case '-' :
        {
            cout << "Skirtumas yra lygus: " << atimti(mas, n, suma);
        }
        break;
        default : cout << "Tokio veiksmo nera" << endl;
    }
 
}

注意对 sudeti（）和 atimti（）包含与函数签名对应的实际参数。

Note the changes to the calls to sudeti() and atimti() to include the actual parameters corresponding to the function signatures.
