1、实验十一任务1：程序调试。类静态数据的应用。下列程序设计了一个职工类，职工类中包括职工姓名、薪水和所有职工的薪水总和allSalary。薪水总和员是所有职工对象薪水的统计和，它属于类而不属于某个对象，因而设置为static数据。程序为：#include"stdafx.h"#includeusingnamespacestd;#includeclassEmployee{private:charname[30];floatsalary;staticfloatallSalary;publi

2、c:Employee(char*n,floats){strcpy(name,n);salary=s;allSalary=allSalary+salary;}~Employee(void){}staticfloatGetAllSalary(void){returnallSalary;}};floatEmployee::allSalary=0;voidmain(void){Employeee1("张三",4500);Employeee2("王五",5200);Employeee3("李四",2450);floatall;al

3、l=Employee::GetAllSalary();cout<<"AllSalary="<usingnamespacestd

4、;#includeclasspeople{private:charname[30];floatsalary;staticfloatallSalary;public:people(char*n,floats){strcpy(name,n);salary=s;allSalary=allSalary-salary;}~people(void){}staticfloatGetAllSalary(void){returnallSalary;}};floatpeople::allSalary=10000;void

5、main(void){peoplee1("A",1000);peoplee2("B",500);peoplee3("C",2000);peoplee4("D",1800);floatall;all=people::GetAllSalary();cout<<"访问一次后还剩现金为:"<usingnamespacestd;#includeclassPoint{publi

6、c:Point(doublexx,doubleyy){x=xx;y=yy;}voidGetxy();frienddoubleDistance(Point&a,Point&b);private:doublex,y;};voidPoint::Getxy(){cout<<"("<

7、ointp1(3.0,4.0),p2(6.0,8.0);p1.Getxy();p2.Getxy();doubled=Distance(p1,p2);cout<<"Distanceis"<

8、：#include#includeclassvector{private:doublex,y;public:vector(doublea,doubleb){x=a;y=b;}frienddoubleb(constvector&s,constvector&s1);frienddo
