in the red-black tree moves relative to the left and is prioritized.Process scheduling is based on the ready queue, and the waiting process in the ready queue is an executable state. While the sleep process is in the waiting queue, processes in the wait queue are not selected by the scheduler. When the sleep process wakes up, it goes into the ready queue. There are two kinds of sleep processes, which can be interrupted and non-disruptive. There are several ways to wake up a process that waits f

containers Some basic operations, such as begin and end members, insert operations, resize operations, erase operations, assign operations, relational operators, and so on. Self-growth of vector containers The vector class provides two member functions: Capacity and reserve, which gets the total number of elements that can be stored before the container needs to allocate more storage space, which tells the container how much space should be reserved. Note that capacity is

The code is as follows:#include The final output results are as follows:All the judgments are equal, and the two values printed are 2 and 5.The reasons are as follows:a is the first address of an array whose type is int (*) [5], so +1 is the step size of the number of arrays. pointer plus 1 to add a certain value according to the pointer itself type, different types of pointer +1 after the increase in size . So a + 1 points to the address of the array is out of bounds, note that there is an int

Next, because he is the object, the second "[1]" is understood to take down the element labeled 1, it is clear that this element has not yet been declared.Thus the result of "[1][1]" is undefined, and a becomes a =[undefined], and only an array of elements, which is undefined.Let's look at a slightly more complicated example:var a = [[' A ', 1,2][' B ', 3,4]];[' A ', up] is still a direct amount of an array, but [' B ', 3,4] how to explain it?The first thing to know about ' B ' is that
