C + + Classes initialize objects with colons (member initialization lists) the order in which members are initialized differs from the order in which they are in the constructor initialization list, and in the same order as they do in the class

First, the basic idea of greedy algorithmIn the process of solving, according to some greedy criterion, starting from the initial state of the problem, we can find the optimal solution of each step directly, and finally get the optimal solution of

4.3 Performance of functionsIn the following set of tests, two 3D points were computed on different compilers, using a nonmember friend function, a member function, and a virtual member function, and virtual member function operates in a single,

Concept of function signatureThe function signature mainly includes 1, functions name, 2, parameter list (number of parameters, data type and order); But note that the function signature in the C + + official definition does not include the return

The actual project often encountered many similar operations, such as command code corresponding to the execution function, for such operations, the better way is to use the const array, the command code and operation functions are bound together,
