Having trouble running the Dev-C++ on the compiler, how to properly do this?

1. #include 2. using namespace std; 3. main(){ 4. int hw, empid; 5. float hr, gp, np, taxrate, taxamt; 6. while( cin >> empid >> hw >> hr ){ 7. gp = hw * hr; 8. if( gp > 1000 ) taxrate = 0.30; 9. else if( gp > 800 ) taxrate = 0.20; 10. else if( gp > 500 ) taxrate = 0.10; 11. else taxrate = 0.0; 12. taxamt = gp * taxrate; 13. np = gp - taxamt; 14. cout << "EMPLOYEE ID IS " << empid << endl; 15. cout << "HOURS WORKED ARE " << hw << endl; 16. cout << "HOURLY RATE IS " << hr << endl; 17. cout << "GROSS PAY IS " << gp << endl; 18. cout << "TAX AMOUNT IS " << taxamt << endl; 19. cout << "NET PAY IS " << np << endl << endl; 20. }//WHILE 21. return 0; 22. }//MAIN

In this phase of the payroll system, we are going to include the appropriate tax rate (variable) rather than a fixed tax rate of 10% (constant). The program will also compute the overtime pay.

4A) Assign different tax rates based on the following gross pay:

• If gross pay is more $1000, the tax rate is 30%
• If the gross pay is more than $800.00 and less than or equal to $1000.00, then the tax rate is 20%.
• If the gross pay is more than $500.00 and less than $800.00, then the tax rate is 10%
• If gross pay is more than or equal to 0 and less than or equal to 500 tax rate is 0.

The tax rate will also vary based on marital status. Add 5% to the tax rate of a single person and subtract 5% if head of household.

Declare marital status as a character: S=Single M=Married H=Head of Household

Program should accept either upper case or lower case letters for marital status (e.g. accept M or m).

4B) Compute the overtime pay according to the following formula:

Any hours over 40 are considered time and a half (overtime). You may want to find overtime hours (e.g. hoursworked 40) and overtime pay (e.g. overtimehours*hourlyrate * 1.5).

How do I properly do this?
