Answer 1

Answer:

The program goes as follows  

Comments are used to explain difficult lines

#include<iostream>

#include<fstream>

#include<sstream>

#include<string>

using namespace std;

int main()

{

//Declare String to accept file name

string nm;

//Prompt user for file name

cout<<"Enter File Name: ";

getline(cin,nm);

//Create File

ofstream Myfile(nm.c_str());

//Prompt user for 4 names of movies

string movie;

for(int i = 1;i<5;i++)

{

 cout<<"Please enter a movie title #"<<i<<": ";

 cin>>movie;

 //Write to file, the names of each movies

 Myfile<<movie<<endl;

}

Myfile.close(); // Close file

//Create an Array for four elements

string myArr[4];

//Prepare to read from file to array

ifstream file(nm.c_str());

//Open File

if(file.is_open())

{

 for(int i =0;i<4;i++)

 {

  //Read each line of the file to array (line by line)

  file>>myArr[i];

 }

}

file.close(); // Close file

//Create a reverseOrder.txt file

nm = "reverseOrder.txt";

//Prepare to read into file

ofstream Myfile2(nm.c_str());

for(int j = 3;j>=0;j--)

{

 //Read each line of the file to reverseOrder.txt (line by line)

 Myfile2<<myArr[j]<<endl;

}

Myfile2.close(); //Close File

return 0;

}
