Ideally, this report shoulatell him the summary of items sold on weekdays per category. Then Sam use the product performancereport to determine which items are worth investing in and which ones shouldn't be re-ordered.Revisiting the report for last week, he realized that he made a mistake in entering items in dairy andfruit category. Watermelon has been entered in dairy report under the Yogurt column, and andsales have been entered in fruit report under the Watermelon column. Sam is trying to rearrange theselling history of yogurt and watermelon.yogurtInput File FormatThe format of the data files fruit.txt and dairy.txt is as follows.• The first line is a column header row containing column titles. Each column title is a stringof less than 100 characters containing no spaces referring to a type of fruit (in fruit.txt) or adairy product (in dairy.txt). In this case you can assume that the two input files have the samenumber of lines.• Each subsequent line contains six data items per line separated by spaces. In order, they are:The day of the week as a string containing no spaces with a length of less than 25 characters.Five additional items in each line that are the numbers of each food item (column title refersto the food item) is sold in as a string with length less than 15 characters.• The number of columns in the file is fixed at 6, but the number of lines in the file is arbitrary andcould be anything.Your TasksThe goal of your program is to swap the values in the Watermelon column in the dairy report with thevalues in the Yogurt column in the fruit report.(a) Write a main() function with parameters argc and argv that accept the names of two files(fruit.txt, dairy.txt, with or without file path) as arguments. Make sure you check for the conditionthat at least two arguments were provided (one for each filename) and if not, take appropriateaction.(b) Read the two input data files, swap the data in the Watermelon column of fruits.txt with the Yo-gurt column of dairy.txt and write the corrected data to fruits-revised.txt and dairy-revised.txtrespectively. You may assume that Watermelon is the last column of fruits.txt and that the Yo-gurt column is the last column of dairy.txt. Take care that the header row of each file is notmodified.Hints: There are several different approaches to this with varying degrees of difficulty and complexity.Think before you code. Think especially about what data needs to be stored, and how much of the data reallyneeds to be stored simultaneously.(c) Use the feof () function while reading lines to detect the end of the file since the number of rowsin the files are unknown and mav varyDELLРОСОSHOT ON POCO F1
