c++ get string from text file code example

Example 1: c++ read text file to string

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

int main()
{
  ifstream ifs("myfile.txt");
  //Two ways:
  
  //Assign it at initialization
  string content( (istreambuf_iterator<char>(ifs) ),
                  (istreambuf_iterator<char>()    ) );
  
  //Assign it after initialization
  content.assign( (istreambuf_iterator<char>(ifs) ),
                  (istreambuf_iterator<char>()    ) );
  return 0;
}

Example 2: read text from file c++

#include<iostream>
#include<fstream>

using namespace std;

int main() {

 ifstream myReadFile;
 myReadFile.open("text.txt");
 char output[100];
 if (myReadFile.is_open()) {
 while (!myReadFile.eof()) {


    myReadFile >> output;
    cout<<output;


 }
}
myReadFile.close();
return 0;
}
