Question: The file profitin.txt contains a series of lines, each giving the identification number, quantity, cost, and selling price of items sold in a store during a one day period. Write a program called profit.c which reads the identification numbers, quantities, costs, and selling prices from the input file and computes the total profit as well as the identification number of the most profitable item. The profit can be computed as the running total of quantity times the difference between price and selling cost. Here is a description of a program which finds the total profit but not the most profitable item. Step1: open the file for reading Step2: declare variables id, quantity, cost, price, total and count initialize total and count to zero Step3: repeat the following until the end of the file is reached 3.1) read the id, quantity, cost and price 3.2) increment the count 3.3) add quantity* (price-cost) to the total Step4: print the count (number of values read) and the total profit. You must modify this program to find the most profitable item. Your output should look like: Number of items is: 4 Total profit is: 81.22 Most profitable item has id: 101 Copy and paste your program into the box below.
