Recently a friend of the laptop encountered a strange thing: the laptop battery can not be used, plug in alternating current, showing that 0% of the available power supply has not been charged, that is, has been charged. Notebook for this, 0% available power is connected to the not charging

The first step: void (*) (), you can see that this is a function pointer type. This function has no parameters and no return value.Step Two: (Void (*) ()) 0, which is to cast 0 to the function pointer type, 0 is an address, that

What is the difference between border: 0 and border: none? bordernone What is the difference between border: 0 and border: none:If you set the border of an object to border: 0 and bord

internal component function input output, the desired result is produced (much like the deformation process of the input object). Inputs each pass through a component function, the state of the program will undergo some changes, the whole process is actually the state of the program of the deformation (transformation). So, can it be said that instruction programming corresponds to variable assignment, func

The VOID operator evaluates the given expression and returns directly to the undefined The void operator is usually used only to get The original value of the undefined, typically using void (0)(equivalent to void 0). In the above case, you can also use the global variable undefined instead (assuming it is still the

to distinguish between importance and secondary importance. This is a methodology issue. I have written several posts related to this, such as "how to choose it technology books" and "Do the right thing ", later, I will continue to write related posts (some of which are included in this series), hoping to help everyone.Finally, to give everyone a better impression, let's take a look at Steve Jobs's famous saying:Every day, I look into the mirror and

In JavaScript, Void is an operator that specifies that you want to evaluate an expression but not return a value.void operator usage format is as follows:1. javascript:void (expression)2. Javascript:void expressionExpression is an expression of the Javascript standard to compute. The parentheses on the outer side of th

After adding a const, this function will not change the value of the member function! This function can be accessed by constant objects (const ). Note that the functions with const and without const are two different functions! Use an example to illustrate the differences: # include Virtual void print () const = 0; (1) = 0 indicates that it is a pure virtua

0% available power has been plugged in to the non-charging cause analysis: Notebook battery Causes this phenomenon most of the reason is due to the aging of laptop batteries or daily care caused by the maintenance, for example, a lot of friends laptop battery, often used to run out of battery power until the computer automatically shut down, so it is easy to dam

A piece of http://www.csdn.net/Develop/Read_Article.asp in the chiway translation? Id = 15224 An application disables the buffer by setting so_sndbuf to 0, and then sends a blocking send () call. In this case, the system kernel locks the buffer of the application until the receiver confirms that it has received the entire buffer before sending () calls are returned. It seems that this is a simple method to
