1.Convert the C program to C++. Replace ALL of the calls to the standard C I/O functions printf(), scanf(), fprintf() and fscanf() to the C++ standard cin, cout, and fstream operators. Your C++ program can not include ANY calls to printf(), scanf(), fprintf() or fscanf() and can reference only the C++ header files, not any of the standard C header files. You must also remove any other C-specific syntax and replace it with C++ syntax. For example, all of the #define statements should be replaced by C++ consts, all of the character arrays should be replace with C++ strings, etc

Once you have converted the program to C++, modify the program to implement the following features (using C++ features and syntax): 1. Modify the program to take command line arguments using argc and argv[] to input the name of the input file the command line. If the user runs the program incorrectly from the command line by failing to enter the filename, OR enters a first argument of /?, the program should print the following message: Program to keep a list of parts from a catalog. Usage: [input_file_name] Where comes from argv[0]. If the user enters the name of an input file that cannot be opened correctly for reading, the program should print out the following message and exit: ERROR: file cannot be opened! Usage: [input_file_name] Where is the name of the input file that the user input on the command line. 2. Modify the program to add a function to sort the list of parts by manufacturer part number. 3. Modify the main routine to implement a main menu to allow the user to select the operation you want the program to perform. The main menu should print out like below: Enter option: (0) Sort and print the Catalog by part number (1) Sort and print the Catalog by price (2) Sort and print the Catalog by manufacturer's part number (3) Exit the program Choice ? The program should perform the requested operation and then print out the menu again. This process should repeat until the user selects option 3 to exit the program
