VisualLeakDetector下载地址：https://kinddragon.github.io/vld/

安装过程自动添加环境变量，自动关联VS并可以在新建的工程中默认添加了VisualLeakDetector头文件与库

安装完成后在VisualLeakDetector安装目录下找到vld.ini文件，修改

ReportTo = both

如果在后面测试的时候call stack没有输出信息，则修改

ReportEncoding = unicode

测试例程：

#ifdef _DEBUG
#include <vld.h>
#endif // DEBUG
#include <iostream>
#include <windows.h>
using namespace std;
int main(int argc, char** argv)

    char* vldPtr = new char;
    char* vldPtr2 = new char[100];
    Sleep(1000);
    //delete vldPtr;
    //delete[]vldPtr2;
    return 0;

调试运行，将会出现相应的内存泄露信息，双击发生内存泄露信息中的定位信息，会自动跳到发生内存泄露的语句，如下面的：
