C PROGRAM

At the end of each month, a company processes payroll for its employees. The company would like to calculate the employees salaries after taxes have been deducted. The data for all employees is stored in a text file. The company would like to generate a report that shows all the information for payroll.

Write a C program that reads employees numbers and monthly salaries from a text file. The program should output each employee's number, salary, taxes, and gross pay (salary after taxes). Output a summary for the total in each category. See the sample output below. The tax rate is based on the following scale:

0% for salaries below $1,000.

10% for salaries between $1,000 and $2,000.

15% for salaries of $2,000 or more.

Each line in the file contains an employee's number followed by his/her salary. Output the total salaries, total taxes, and total gross pay (use three variables to accumulate each total).

Create a data file called "payroll.txt" and include all employee data as shown in the sample data file below.

Requirements:

Write a function that calculates and returns the taxes

taxes = calculate_taxes(salary);

Write a function that outputs a single salary line to the output file

output_salary(emp_number, salary, taxes);

Write a function that outputs the summary line to the output file

output_summary(total_salaries, total_taxes);

Use a field width in your output to line up the columns: 7 for employee number and 15 for all others (left justified).
