//C++ program to create a file.

#include <iostream>
#include <fstream>
 
using namespace std;
 
int main()
{
   fstream file; //object of fstream class
    
   //opening file "sample.txt" in out(write) mode
   file.open("sample.txt",ios::out);
    
   if(!file)
   {
       cout<<"Error in creating file!!!";
       return 0;
   }
    
   cout<<"File created successfully.";
    
   //closing the file
   file.close();
    
   return 0;
}
