CauseAn accidental encounter with a strange bug, the phenomenon is that the same C + + code using the gcc4.4.x version before the optimization and optimization of the result is not the same, optimized code logic is incorrect.The sample code is as follows://main.cpp#include This code was used g++ -O0 and compiled separately g++ -O1 , the result is surprising, when tt=4, switch jumped to 1 of the branch.$ g++ -O0 -g -o main main.cpp$ ./maincase default,

In the experience of dual systems, we also need to set some default parameters, such as the default boot system how to set up? How to switch two systems?

WIN8 system is the latest and most practical system software, it is easy to operate, simple and fast. Now a lot of users are starting to use the WIN8 system because it is simpler and more practical than the other older versions of the system's operating procedures. And its operation skill has a lot of, but below we only focus on two quick Win8 system switch Input method skill, other skill everybody also can Baidu to understand. One, use win key + Spa

Many people's computers are equipped with many input methods, while Ctrl + Space is a very fast switching input method. Because with this you don't have to press Ctrl+shift to change, and if CTRL + space can not switch to the input method you want, then we usually switch input method when it caused a lot of trouble, like small knitting I general computer inside there are 3 kinds of input method, I am accust

sequential structure. The sequential structure is executed from top to bottom, and the preceding code executes first, followed by the following code. This means that if there is no process control, the language room in the Java method executes the stream sequentially, executing each statement from top to bottom (that is, sequentially according to the order in which the statement appears). Branching structure: Select one of the two branches or branches to perform according to the criteria. First

The C language does not limit the number of branches that if else can handle, but when there are too many branches, it is not convenient to use if else, and it is easy to have an if else pairing error. For example, enter an integer that outputs the corresponding number of days of the week in English for that integer: #include Run Result: Input integer Number:3Wednesday The C language also provides an alternative statement--switch state

The switch statement in Swift, as long as the first match (case) completes, not through the bottom of subsequent cases (case), as it does in C and C + + programming languages. The following are common syntax for switch statements in C and C + +: Copy Code code as follows: switch (expression) { Case Constant-expression: statement (s); Break *

Android animation to achieve switch button animation (property animation translation animation), recently done projects, according to the project needs, there is a function to achieve similar switch animation effect, through their own thinking and online search information, and finally resolved, here on the record: In Android, some cool animations are really attractive places, let's see the Feast for the e

Basic ISSUESThe FreeRTOS will perform a process switchover in the zone where the critical area is taskenter_critical () and the taskexit_critical () package. That is, the process switches when the interrupt is closed. we already know that even if the interrupt is off, PowerPC's SC interrupt can be responded to. But the clock is interrupted? This is an external interrupt and cannot be responded to. So when is the interruption open? Open the inte

With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used.
