内存泄漏检测，只有简单的几行代码，但非常好用，只要包含头文件并把代码复制到可能有泄漏的代码后面，编译时就会提示是否泄漏内存和泄漏内存的大小。给出了一个动态分配数组但没有delete的适用例子。-Memory leak detection, only a simple few lines of code, but very easy to use, if contains the header files and copy the code may have leaked the code behind, compile-time will be prompted to leak memory and the size of the memory leak. Gives a dynamically allocated array but did not delete the application examples.
