Thread. Sleep (0), Thread. Sleep (0) The article I saw was well written. We may often use the Thread. Sleep function to suspend the Thread for a period of time. Do you understand the usage of this function correctly? Consider the following two questions:Suppose it is 12:00:00. 000. If I call Thread. Sleep (1000), this Thread will not be awakened at 12:00:01. 000?Someone's Code uses a seemingly unknown sent
exception. ' V ' indicates that this function throws an error.For example:void Lua_settable (lua_state *l, int index); [-2, +0, e][-2, +0, e] with the ball settable will pop 2 elements into 0 elements, this function will throw an error. Here we list all functions and types from the C API in alphabetical order. Each function has a indicator like this:[-O, +p, x]T
The role of new string[0]For example: string[] result = Set.toarray (new string[0]);Of the public methods of collection, ToArray () is the more important one.However, there is a disadvantage to using toarray () without parameters, that is, the converted array type is object[]. Although the object array is not useless, the problem comes when you really want to use a specific type of array, such as string[. A

The usual impression of the heap and stack is two kinds of data structure, the stack is advanced, the heap is FIFO. Here's a common example of the analysis:Main.cppint a = 0; Global initialization ZoneChar *p1; Global uninitialized ZoneMain (){int b; StackChar s[] = "ABC"; StackChar *p2; StackChar *p3 = "123456"; 123456\0 in the constant area, p3 on the stack.static int c =
statement that can run correctly to meet the uncertainties in the Multi-condition query page.Where 1 = 0; this condition is always false, and no data is returned. Only the table structure is available for quick table creation."SELECT * FROM strName WHERE 1 = 0"; this select statement is mainly used to read the table structure without considering the data in the
This is indeed a bit confusing:1. the command line parameter "console = ttySAC0" has nothing to do with the/dev/directory. It is used to select the device from which to output the kernel and driver printk information: ① In kernel/printk. c, there is this line of code: __setup("console=", console_setup); For the command line parameter "console = ttySAC0", the console_setup function will parse the device name and index:The name is ttySAC and the index is 0
A double in C + + has a negative 0 (negative zero). Negative 0 is meaningful in some calculations. For example:1.0/0.0 = = infinity1.0/-0.0 ==–infinityIn addition, negative 0 is also used in some mathematical functions, such as sqrt (Std::complex)At the same time, the addition and subtraction of 0 and minus Zero also h
