Answer 1

#include <iostream>
#include <fstream>
using namespace std;

int main () {
//Declare an output file stream object
ofstream MyFile1("test.txt");

//Write a string into the stream with new line
//character at the end
MyFile1 << "This is awesome! \n";
//Close the stream
MyFile1.close();

//Declare a buffer for file read
string line;
//Declare input file stream object
ifstream MyFile("test.txt");
//print the content of the file in the console
//repeat while there's still lines to read
while ( getline (MyFile, line) ) {
cout << line << '\n';
}
//Close input file stream
MyFile.close();
}
