In Java, there is a very powerful keyword called synchronized, you can easily implement thread synchronization. Today is a whimsical attempt to emulate a similar one in C + +.Recently in the study of C + + STL, see smart Pointer This chapter, all

3.3 Observer Mode (OBSERVER)/publish-Subscribe modeMotivation:During the software build process, we need to establish a "notification dependency" for some objects-the state of an object (the target object) is changed, and all dependent objects (the

Chinese New Year more and more bored, post couplets after doing nothing to look at the previous C language. There are some things that you want to write down about priority issues.When I study the priority, remember our teacher handsome said: After

Suppose you want to sort the sequence with n number in ascending order, the bubble sort algorithm step is:1, starting from the first element in the array of storage sequence to the last element, in turn, the adjacent two numbers are compared, if the

Template method Mode:Definition: A skeleton that defines an algorithm in an operation. Instead, some of the steps are extended to subclasses. The template method allows subclasses to redefine some specific steps of the algorithm without altering the

The Out keyword causes parameters to be passed by reference. This is similar to the REF keyword, except that the ref requires that the variable be initialized before it is passed. To use an out parameter, both the method definition and the calling

Simple understanding: The closure variable is the scope of the local variable is extended to the callback function, which occurs when the anonymous method is registered to the delegate, while the anonymous method uses the external local

OC's Protocol　　A protocol is a rule, and defining a protocol is tantamount to making a rule. Classes in OC can obey rules, and classes that comply with the Protocol are equivalent to one or more capabilities. Some properties and methods are put into

Overview:I²C is the abbreviation for inter-integrated Circuit, pronounced as "eye-squared cee" or "Eye-two-cee", which is a two-wire interface.I²C uses only two bidirectional lines, one Serial Data line (SDA) and the other Serial Clock (SCL).SCL:
