Quick sort of dynamic display is relatively simple, not much to say, directly on the code:Quick Sort Dynamic Display #include #include   #include  void swap ( INTARRY[],INTNUM1,INTNUM2) {              int temp = arry[num1];        

ConstThe const design is to kill # define, there are three main aspects:1. Constants#include #define PI 3.1415926void main () {int a = 5;int B = 3;cout In this program, we look at the results, we can see that the const is also in the stack, and the

Static: Sharing is communicationIn a nutshell: local scope, global lifetime.Why design to be like this?Take a look at this piece of code:#include #includestring.h>classcsmallone{ Public: Csmallone (intSMA); intA;}; Csmallone::csmallone (intSMA)
