Write a C program for the Grocery store checkout counter.
Ask and Enter the price of each item. The program should
display the total bill amount using one decimal digit. Use a tax rate of 8.5%. Use increment operator to keep
track of the number of items processed. Compute the bill amount using the tax rate. Show the bill amount (1 decimal digit)and the number of items processed.
(Assume the counter can process less than or equal to 5 items only -i,e, Express Lane counter)
