    std::string line;
    std::ofstream collegeWrite(collegeFile);
    for (int i = 1; i < 4; i++)
    {
        std::cout << "Enter name" << i << "college: ";
        std::getline(std::cin, line);
        collegeWrite << line << std::endl;
    }
    collegeWrite.close();
    std::ifstream collegeRead(collegeFile);
    std::ofstream universeWrite(universeFile);
    while (std::getline(collegeRead, line))
    {
        universeWrite << line << std::endl;
    }
    collegeRead.close();
    universeWrite.close();
    std::ifstream universeRead(universeFile);
    while (std::getline(universeRead, line)) 
    {
        std::cout << line << std::endl;
        //simulate underline
        for (int i = 0; i < line.length(); i++) 
        {
            std::cout << "-";
        }
        std::cout << std::endl;
    }
    universeRead.close();
