I just made a program to output the number one googleplex, but its such a huge number (2.57 MB) that windows cuts off a large chunk of the top of it, so now I need to modify it to print to a .txt file. How would I go about doing this?

//I want 1 followed by this many zeroes: 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
//100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000 * 100000

#include <iostream>

using namespace std;

int print(int thr,int until);

int main() {
  int threes=0;
  int power=0;
  cout << "I now present to you.. a googolplex!\n\n";
  while(power<20) {
    print(threes, 100000);
    power++;
  }
  cout << "\n\nDONE!\n";
  for(;;);
}

int print(int thr,int until) {
  int repetitions=0;
  while (repetitions<until) {
    cout << "0";
    thr++;
    if(thr>=3) {
      cout << ",";
      thr=0;
    }
    repetitions++;
  }
  return thr;  
}
