C++ code: How to add a file to read/write to a code that prompt user to add (write) infos and read infos from the file?

Answer 1

To create a file in c++ and write data to it it can be done as follows

#include <fstream>

#include <iostream>

#include<string>

using namespace std;

int main()

{

ofstream fout;

//Creating the file sample.txt

fout.open("sample.txt");

if(fout.is_open())

{

//writing content to the file

fout<<"Hello Good Day";

}

//Reading from the file

ifstream fin;

fin.open("sample.txt");

if(fin.is_open())

{

string line;

//reading from the file

while(getline(fin,line))

{

cout<<line;

}

}

return 0;

}
