Solution

//C++ code to output 1:20 in new file

#include <iostream>
#include <string.h>
#include <fstream>
#include <iomanip>
#include <cctype>
#include <vector>

using namespace std;

int main()
{  
   ofstream outputFile;
   outputFile.open (\"out.txt\");
  
   int number = 1;
   while(number <= 20)
   {
       outputFile << number;
       outputFile << \"\ \";
       number = number + 1;
   }

   outputFile.close();
return 0;
}
