Const detail in C + +From http://blog.csdn.net/lwbeyond/article/details/6187501I. The role of cons(1) const constants can be defined const int max=100; int Array[max]; (2) Can protect the modified things, prevent accidental

The idea of the bubbling sorting algorithm is to constantly exchange and complete the final sort by swapping.The basic idea of choosing a sort is that each trip selects the smallest record in the n-i+1 record, which is the record of the first I.1

The Chinese meaning of Mutalbe is "mutable, variable", and constant (both const in C + +) are antonyms.In C + +, mutable is also set to break the limits of Const. Variables that are modified by mutable will always be in a mutable state, even in a

C + + supports multiple inheritance, however multiple inheritance can cause some strange problems, and I encountered a pointer conversion problem in the previous period, very typical.Let's look at a simple test code:#include using namespace
