in C++ please! 1. Comments at the top of your .cpp file.2. Use only C++ headers. For C++ strings use #include ; forstandard input and output use #include to accessstd::cout; std::cin.3. An example of entering two categories using two string variables isshown below. Modify this code to add a while loop so five categoriescan be entered:std::string categories = ""; std::string category = "";std::cout << "Enter in the category names for your five-bar bar chart:\n";//first category appended to categories std::cin>> category;categories += category + "*";//second category appended to categories std::cin>> category;categories += category + "*";4. Use std::string.find and std::string.substr to extract each categoryname from the string categories using the marker placed during theprevious step. The marker used in the example above was the '*'symbol. Store each category name in a string variable. For example,in the code snippet above the first category name can be retrievedbyint marker_index = categories.find("*");std::string category_one = categories.substr(0,marker_index);5. After each category name is extracted from the categories variable,ask the user to enter in a category amount for each category.6. Compute and store the total amount entered to be used for creatingthe bar chart.7. Create the bar chart using the category names, category amountsand the total using the C++ stream formatting options. While anycombination of stream formatting can be used, do not use any loops(e.g. for, while, etc.) to print out the bar chart symbols. Refer to theincluded references and textbook for how to use std::cout.fill(),std::cout.width(), std::left, std::right and std::cout.precision ().8. To ensure that the bar chart lines up correctly given that eachcategory name may be a different length, use the std::string.size() orstd::string.length() to find the longest category name. Use this lengthto offset the start of drawing the bar.9. Ensure that the number of symbols printed equals the categorypercent of the category. For example if the total is 100, and thecategory amount is 25, then the percent of total is 25/100 * 100 =25% and 25 symbols will be printed for the bar plus the percent labelrounded to the nearest two decimal places. If the percent of totalwas 24.91, then 25 '*"s would print plus the five characters in thepercenatage (24.99). For example,category_one ********category_two *****************25.00*********24.9910. Pause the program so the user has time to inspect the output usingany standard C++ code (e.g. cin, etc.).1
