confirm its location in memory, the static function does not need to be instantiated, so the static method cannot use the
Why can't I declare a static variable inside a method?Because a static variable is a common variable for all instances of a class, it is a global variable within the scope of the class. If you de
Software static analysis and tool Klocwork Introduction
1. Software static analysis
Software static analysis does not need to execute program code, can discover the
, static global variable is too large, but that can cause stack overflow.
Answer and Analysis:
For a,b: According to the description in this section B), we know that a,b is correct.
For C: According to the description in this overview section a), we know that C is correct (the so-called function reentrant problem, described below in detail).
For d: Static var
, which can instruct the compiler to save the variable in the static storage area of the program, this achieves the goal and keeps the access range of this variable unchanged. Ii. control visibility and connection type: Static also has a function, which limits the visible scope of the variable to the compilation unit and makes it an internal connection. In this case, its antonym is "extern ".
For iPhone development, we use instruments when detecting all of them during execution, but sometimes we can eliminate these in the cradle. Static analysise.
You can run build and analyze directly for the build check. You can also check that the build option is checked in getinfo, and each build is executed. However, you will see that it will waste the analysis time during build, resulting in a long build t
Static represents the meaning of "global" or "static", which modifies member variables and member methods, and can also form statically static blocks of code, but there is no concept of global variables in the Java language.member variables and member methods that are modified by s

Transferred from: http://blog.csdn.net/keyeagle/article/details/6708077Google has nearly three pages of the C language of static content, found that the available information is very little, either long-winded or in the key point of a few words, for beginners who want to dig the underlying principle of the reference is not very large. So, this blog post to the people of the long, the Internet on the integration of data classification, and hand-written
Google in the last three pages of C language static content, can find very little information. Whether it is a lengthy and unintelligible words, in the key position or skip, the learner is not very large. So. I have this blog post, the length of the family, the Internet on the integration of data classification, and hand-coded code verification.C language code is
First look at the process address space:We simply say, from low address to high address, code area and data area, empty, stack area.In the Linux kernel source scenario analysis-the extension of the memory management user stack, we applied the page from the stack area down to the data area above .In the Linux kernel source scenario analysis-the Memory management u

createnewchild (t, M ', label (e)): Creates a new tree node attached to, and the link is tagged as.
To avoid infeasible chain, this approach use a simple test:for any call through this, the receiver class associated with E should match the receiver class associated with the last edge in chain.
use-backedges: Creating a Back-edge from a tree node to some ancestor of this node. In addition, if use-backedges is true, we have an
The link to the static library is basically the same as the link to the target file.obj/.oSame, but there are some differences. This article briefly describes some details of the Linux static library link process.Static Library File Format
Static databases are far different from dynamic databases, and do not involve issues such as symbol relocation. In essence,
Use the FindBugs tool for the first time.
A FindBugs function:
FindBugs is a static analysis tool that examines a class or JAR file and compares bytecode with a set of bug patterns to identify possible problems. With the static analysis tool, the software can be analyzed without actually running the program to find out

window, we can use APK, D, DEX = analyzeapk ("./sample.apk ")
Obtain the APK object, Dex object, and analysis result object respectively.
For the operations on these objects, you can use the tab to list the corresponding methods. For details, see D and Dex.
For example, the APK object can get the corresponding information through get_xxxx, including files, permissions, components, etc. In fact, these functions are the core classes of androguard work
Below is a list of some tools that can help you examine your Java source code for potential problems:

are actually beginning to feel the pressure. The previous introduction of QA engineers for start-up software companies also applies to DBA. As versions are published more frequently, DBAs receive more and more SQL scripts to be written, checked, modified, or optimized. DBA is the last line of defense for data quality, data security, and data platform performance. Therefore, DBA is the first person to respond to problems.
Among the Fortune 500 DBAs that work with us, the most time-consuming task
Although IDA, VTS, and other tools in the free version of windows can be used for static analysis, these tools are not suitable for manual analysis. However, for project development, great extensions are ignored. In androguard, It is very suitable for expansion or transplantation into a module of your own project. Although I have heard of it, I have only recently
