#include<iostream>
#include <fstream>
#include<string>
#define startunder "\033[4m"
#define finishunder "\033[0m"
using namespace std;


int main()
{
    // creating and writing data to a file college.txt
    ofstream file1("college.txt");
    if (!file1)
    {
        cout << "Error opening file program terminated" << endl;
        return 1;
    }
    file1 << "Lovely Professional University" << endl;
    file1 << "Thapar Institute of Engineering and Technology" << endl;
    file1 << "Dr B R Ambedkar National Institute of Technology" << endl;
    file1.close();
    // copy file college.txt to university.txt
    string line;
    ofstream file2("university.txt");
    if (!file2)
    {
        cout << "Error opening file program terminated" << endl;
        return 1;
    }
    ifstream file3("college.txt");
    if (!file3)
    {
        cout << "Error opening file program terminated" << endl;
        return 1;
    }

    while (getline(file3, line))
    {
        file2 << line << endl;
    }
        file3.close();
        file1.close();
   // output underlined file
        ifstream file4("university.txt");
        if (!file4)
        {
            cout << "Error opening file program terminated" << endl;
            return 1;
        }
        while(getline(file4, line))
        {
       cout << startunder << line << endl << finishunder;
        }
        file4.close();
