C++编写静态库

1、新建项目创建静态库staticLib1.

demoStaticLib.h

#pragma once
class ArrayTool
{
public:
	int Max(const int* lpHead, const int nLength);
	int Sum(const int* lpHead, const int nLength);
};

demoStaticLib.cpp

#include "pch.h"
#include "demoStaticLib.h"

int ArrayTool::Max(const int* lpHead, const int nLength)
{
    int nMaxVal = lpHead[0];
    for (int i = 0; i < nLength; i++) {
        if (nMaxVal < lpHead[i])
            nMaxVal = lpHead[i];
    }

    return nMaxVal;
}

int ArrayTool::Sum(const int* lpHead, const int nLength)
{
    int nTotal = 0;
    for (int i = 0; i < nLength; i++ ) {
        nTotal += lpHead[i];
    }
    return nTotal;
}

2、创建引用其的项目useStaticApp

2、1添加引用。将生成lib文件应用

2、2 项目属性->配置属性->C++->附件包含目录引入上一个项目的目录

修改文件 useStaticApp.cpp

#include <iostream>
#include "demoStaticLib.h"
int main()
{
    int nArr[] = { 1,34,6,7,8,35,67 };
    ArrayTool at;
    int nLen = sizeof(nArr) / sizeof(int);
    std::cout << "数组最大值 " << at.Max(nArr, nLen) << std::endl;
    std::cout << "数组元素之和 " << at.Sum(nArr, nLen) << std::endl;
    return 0;
}

2、邮件点击、生成

useStaticApp设为项目，然后运行调试
