Question

intructions: please don't use struture and pointers

Write a program that displays a weekly payroll report. A loop in the program should ask the user for the employee number, gross pay, state tax, federal tax, and FICA withholdings. The loop will terminate when 0 is entered for the employee number. After the data is entered, the program should display totals for gross pay, state tax, federal tax, FICA withholdings, and net pay.

Input Validation: Do not accept negative numbers for any of the items entered. Do not accept values for state, federal, or FICA withholdings that are greater than the gross pay. If the sum of state tax + federal tax + FICA withholdings for any employee is greater than gross pay, print an error message and ask the user to reenter the data for that employee.

C++ code for Weekly payroll report:

using namespace std;

int main()

       int total_federal_tax=0;
       int total_FICA_withholdings=0;
       
       while(1)
       {   
           //variabls to store employee details
   
           int employee_number;
               int gross_pay;
               int state_tax;

               cin>>employee_number;
           
           // break the loop if employee number is 0
               if(employee_number==0)
               break;

                       total_gross_pay+= gross_pay;

                       cout<<endl<<endl;

       }//end of while loop 

        cout<<"----------------------------------------------"<<endl<<endl;
