Simple Payroll Program in C

SIMPLE PAYROLL PROGRAM IN C

Machine Problem in C

Write and design a payroll program that will ask the user how many days an employee work in the company and then the salary rate per day. In addition, the program also will ask the user the SSS, PAG-IBIG, BIR and PHILHEALTH contributions. The payroll program will compute the gross salary, total deductions, and net salary and display the result on the screen.
