Alternate way to write in a file instead of using "<<" in c++?

Question

When we load a file using fstream header, we use >> and getline() to get one complete line.

When writing it to an output file we use <<

Is there any other alternate way to write the line in the output file instead of <<?

Answer 1

it is very simple. look the code below

#include <iostream>
  using namespace std;

  int main()
    {
     char a('a');
     // cout
      cout.put(a);   // can only be used for characters
      string hello;
     //cin
       cin.getline(hello);
    //or
       getline(cin,hello);
    }

see, it was too easy;
