In Main () first enter the number of employees, as a parameter passed to the member function of input workers ' wages, and then use the mechanism of dynamic allocation of memory, to open up a continuous space of the size exactly, complete the above work. * Input Description: NULL; * Program output: Output as required.

The code is as follows:

#include <iostream>using namespace Std;class salary{public:void Set_salarys ();    Enter the employee's salary (input-1 is the end of the payroll input), and the payroll is saved to the salary array, and the actual number is saved in the numbers.         void Add_salarys (int x);            Give everyone a raise x yuan pay void Sort_salarys ();            Sort of the Payroll void Show_salarys ();              Display wage information private:double *salarys;                      Multi-person salary int number;    Actual number};int Main () {Salary s;    S.set_salarys ();    S.show_salarys ();    S.add_salarys (500);    S.sort_salarys ();    S.show_salarys (); return 0;}    void Salary::set_salarys () {int i;    Double money;    cout<< "Please enter the number of employees:";    cin>>number;    Salarys=new Double[number];    cout<< "Please enter the employee's salary:";        for (i=0;i<number;i++) {cin>>money;    Salarys[i]=money;    }}void Salary::add_salarys (int x) {int i; for (i=0;i<number;i++) salarys[i]+=x;}    void Salary::sort_salarys () {int i,j;    Double T; for (i=0;i<number-1;i++) for (j=0;j<number-i-1;j++if (salarys[j]<salarys[j+1])//from high to low arrangement {T=SALARYS[J];                SALARYS[J]=SALARYS[J+1];            salarys[j+1]=t;    }}void Salary::show_salarys () {int i; for (i=0;i<number;i++) Cout<<salarys[i]<<endl;}

Operation Result:
