Requirements a) Write functions to perform the following: DO NOT USE GLOBALVARIABLES1 [14 marks] 1. read Data0: A function to read all the data from the given file and store them in the arrays or vector received as parameters. The function must returm the value of size of the arrays Ge the number of records read from the file). The function should close the file immediately aner all the 2. displayCarso: A void function to display the contents of the arrays or vector on the computers console in a nice tabular format. It should receive as parameters all the parallel and the size or just the vector an additional double display Cars 0: A void function similar to the above one, but with parameter called askedPrice Rows to be displayed are those for which the price askedPrice displayCars 0: A void function similar to the above one, but instead of the askedPrice, it receives a string parameter called askedMaker. Rows displayed are those for which the maker 5. displayHighstocko: A void function similar to the function in question a2. but rows displayed are those for which the amount m4. 6, displayLeastExpensive0: A void function similar to that of question aa, but it displays details of the least expensive motor by the askedMaker. 7. gerTotalvalue0: A double function to return the value of all the cars Chint: the sum of price amount for all the cars) b) In the main0 function, your program should do the following: (No menu is required) lsmar Declare the vector or parallel amays with appropriate types and a reasonable size. 1. Load the vector or the arrays with data from the given file. 2. Display all the cars your autoDealer have. 3. Display all the cars with price 85000. 4. Display all the cars made by Nissan. 5. Display the least expensive car by Toyota. 6. Display the total value of the cars in the given file. 7. Display the high stock List. c) Run your program. Take a screenshot of the output window. Add a copy of your cpp file and the screenshot (s) to the MS-Word document. Save your file and project.](https://media.cheggcdn.com/media%2F9c5%2F9c523736-1f20-4039-a521-5adc528feaea%2Fimage)
