write a program to calculate allowance of salesmen

 /* An industrial organization wants to computerize the allowance calculations.
Given the monthly sales for the salesman, the rules for the calculations are as follows:
i. If the total sales is less than Rs. 10000/- there is no allowance.
ii. If the total sales is between Rs. 10000/- and Rs. 20000/- then the allowance is 10%
of the sales amount or Rs. 1800/- whichever is minimum.
iii. If the total sales is greater than or equal to Rs. 20000/- then the allowance is
20% of the sales amount or 6000/- whichever is minimum.
Write a program using a function to calculate the allowance.
