一、Visual Leak Detector的安装

1、Visual Leak Detector安装包下载

Visual Leak Detector | Enhanced Memory Leak Detection for Visual C++ (kinddragon.github.io)https://kinddragon.github.io/vld/

2、安装Visual Leak Detector

双击安装包，进行安装

点击下一步

二、配置环境变量

打开刚刚自己对应选择的安装路径文件夹下，有如下文件

打开开始菜单，系统选项卡，选择右边高级系统设置

选择环境变量

双击path后面，横线上的，进行添加环境变量

添加对应路径，根据刚刚配置的文件路径进行设置

三、使用测试

打开Vistual Studio2019，或其它版本，新建一个c++程序，添加库目录等

将如下测试代码加入进去

#include "vld.h"

#include <iostream>

using namespace std;

int main(void)
{
int x = 5;

int* y;
y = new int(16);

cout << *y;

int* w = new int(4);

cout << *w << endl;

cout << x << endl;
}

然后点击运行，这里我们能看到准确的泄漏行号，以及泄露的字节数、数据，如下
