how to handle files with c++
#include <iostream>
#include <fstream>
#include <windows.h>
using namespace std;
int main () {
//write
ofstream writer("file.txt");
string test = " /nTest2";
writer << "Test text";
writer << test;
writer.close();
//read
ifstream reader("file.txt");
string getter
while (getline(reader, getter))
{
dataAdderInp >> getter;
}
cout << getter;
// add a new text to an exist file and keep the text that is in it.
ofstream add("file.txt", std::ios::out | std::ios::app);
add << "/n bonus text";
add.close();
return 0;
}
//if you run this you will get:
// -a file with: "Text text /n Test2"
// -and a console output: "Text text /n Test2"
// -and in the end your file will get a text, so it will looks like: "Text text /n Test2 /n bonus text"
