The declaration of the JS function.Declare the format of the function such as the following:Function name (List of parameters) {//functions statement; return value;}See the detailed function declaration.1. Common functions2, with the function of the number of parametersYou need to pay attention here. For the JS function of a control that produces a callback, such as a similar button, the return false is added at the end of the function, and no callback is given.Let's say that for some simple ope

as separate interfaces. Rather than the behavior of the computer.5, is-a,has-a,like-a How to applyAssuming you are sure that the two-piece object is a is-a relationship, you should use inheritance at this point. For example, a diamond, a circle, and a square are all shapes. Then they should all inherit from the shape class.If you are sure that the two-piece object is a has-a relationship, you should use aggregations at this point. For example, the computer is composed of display, CPU, hard disk

Finally, the built-up tree BFS can be written hierarchically traversed. The AC code is as follows: #include
