003 implement string inversion reverse, 003 string reverse The code is simple. // Write code to flip a C-style string. (C-style means that "abcd" must be expressed in five characters, including the end character at the end.) # include Compile the void reverse_string (char * str) function. You can reverse the string function without using any library function. For example, convert "abcd" to "dcba" Void

Unity Learning -- 003: Role controller (medium), unity -- 003 In the previous article "unity learning-003: Role controller (I)", I checked the basic implementation methods of role control. The mouse and keyboard control were rough. This article mainly introduces several role control methods encapsulated by unity, Next, we will introduce several mainstream role co

then filters based on the condition goals>=5. Assuming conformance then add this element to the newly created set. Through the above study. We should have a deep impression of the LAMDBA expression, which declares a functional interface, which is simply an interface of an abstract method, and is implemented with a LAMDBA expression.Or use the functionIn a traditional Java class. There is also an interface that has only an abstract method. For example, create a new thread java.util the Runnable

In the previous Unity Learning--003: Role Controller (above) , saw the basic implementation of the point role control, mouse and keyboard control more rough implementation. In this article, we mainly introduce the role control methods of several unity packages,Then, it is expected to introduce several mainstream role control methods in the next chapter.Words don't say much, open to engage:is still the last few models dragged over　　However, this time a
