Result output: It is output to the debugging window of VC.
Design Concept: register the _ crtsetallochook hook function and use the CRT debug heap provided by VC.
Advantages and disadvantages: You can obtain the call stack of the memory leak point and complete data of the memory leak.

PMD is a Java program code checker that is released using the BSD protocol. The tool can check whether the Java code contains unused variables, contains empty fetch blocks, contains unnecessary objects, and so on. The software is powerful and highly efficient, and is a good helper for Java programmer Debug. the supported editors for PMD include:JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, Codeguide, Netbeans/sun Java Studio enterprise/creator, Intelli
Today, we are excited to release a new version of the flow's delicacy, a JavaScript static type checker. Flow adds static type checking for JavaScript to improve development efficiency and code quality. More specifically, the benefits of static type checking, like early error checking, help you find bugs that can only be discovered at runtime, and code IntelliSense, which helps code maintenance, lookup, refactoring, and optimization.

In an embedded operating system, Bootloader is run before the operating system kernel runs. You can initialize a hardware device, establish a memory space map, and bring the system's hardware and software environment to a suitable state to prepare the correct environment for the final call to the operating system kernel. In embedded systems, there is usually no firmware program like the BIOS (note that some embedded CPUs also embed a short startup pro
