Today, the teacher told the tree-like array, Ben Konjac Konjac a little mengmengdongdong, but the basic template I still remember;First, the principle:Learn a tree-like array tonight ... So I'm going to summarize my understanding of it ...This picture is on the internet casually looking for ...Can be drawn from the graph:C1=A1;C2=C2+C1=A1+A2;C3=A3;C4=C4+C3+C2=A1+A2+A3+A4;C5=A5;C6=C6+C5=A5+A6;C7=a7;C8=c8+c7+c6+c4=a1+a2+a3+a4+a5+a6+a7+a8;Top k items and:S1=C1=A1;S2=C2+C1=A1+A2;S3=C3=A3;S4=C4+C3+C2

We see that the 17th line of the program defines a two-dimensional array A, and on line 18th defines the pointer p, which points to the address of the first element of the two-dimensional array. Next we print this array, and in line 35th we call the PrintArray function to print the array. The results are as followsWe see that two-dimensional arrays are also distributed in memory in one dimension . Then one-dimensional array name represents the address of the first element of the array, and the

function.2> inherited interfaces and missing implementations: impure virtual functions. This can lead to dangerous situations. Because this interface does not require the customer to force Implementation, it can cause errors if the customer is not implemented if necessary. The solution is: the base class provides a missing implementation of the member function, when the subclass inherits the interface, if you want the default implementation, call the base class directly the provided member func
