How to insert a new line in a text file using C++ - io

Question

I have to write a program in C++ that asks user to enter lines and store them in a text file.
void create_file(char name[80])
{
char line[80],op;
ofstream fout(name);
do
{
cout << "Enter the line you want to enter in the file:" << endl << endl;
gets(line);
fout << line << endl;
cout << "\nDo you want to enter another line?" << endl;
cin >> op;
}
while(tolower(op) == 'y');
cout << "File created successfully!" << endl;
fout.close();
}
The problem is that the text is not being stored in different lines.
I have to use Turbo C++ for this program.
Minimal, Reproducible Example:
#include<iostream>
#include<fstream>
#include<conio.h>
#include<stdio.h>
#include<ctype.h>
using namespace std;
void show(char name[80])
{
char line[800];
cout << "Contents of the file:" << endl << endl;
ifstream fin (name);
while(!fin.eof())
{
fin.getline(line,80);
if(fin.eof())
break;
cout << line;
}
}
void create_file(char name[80])
{
char line[80],op;
ofstream fout(name);
do
{
cout << "Enter the line you want to enter in the file:" << endl << endl;
fflush(stdin);
gets(line);
fout << line << endl;
cout << "\nDo you want to enter another line?" << endl;
fflush(stdin);
cin >> op;
}
while(tolower(op) == 'y');
cout << "File created successfully!" << endl;
fout.close();
show(name);
}
int main()
{
char name1[80];
cout <<"Enter the name of the text file:" << endl;
gets(name1);
create_file(name1);
return 0;
}
