Here is a step-by-step guide on how to write a program in C++ to solve this problem: 1. Include necessary libraries: ```cpp #include #include #include #include ``` 2. Declare necessary variables: ```cpp std::string fileName, line, title, rating, time, prevTitle = ""; ``` 3. Get the file name from the user: ```cpp std::cin fileName; ``` 4. Open the file: ```cpp std::ifstream file(fileName); ``` 5. Check if the file is open: ```cpp if (file.is_open()) { ``` 6. Read the file line by line: ```cpp while (getline(file, line)) { ``` 7. Use `std::stringstream` to split the line into time, title, and rating: ```cpp std::stringstream ss(line); getline(ss, time, ','); getline(ss, title, ','); getline(ss, rating); ``` 8. If the title is the same as the previous title, just append the time. Otherwise, print the title, rating, and time: ```cpp if (title == prevTitle) { std::cout

Otherwise, print the title, rating, and time: ```cpp if (title == prevTitle) { std::cout << " " << time; } else { if (!prevTitle.empty()) { std::cout << std::endl; } std::cout << std::left << std::setw(44) << title.substr(0, 44) << " | " << std::right << std::setw(5) << rating << " | " << time; prevTitle = title; } ``` 9. Close the file: ```cpp file.close(); ``` 10. If the file could not be opened, print an error message: ```cpp } else { std::cout << "Unable to open file"; } ``` This program reads the CSV file line by line, splits each line into time, title, and rating, and prints the title, rating, and time in the required format. If the title is the same as the previous title, it just appends the time.
