I don't really understand what you meant, but I'll just say what I
think your answer is.  (I didn't know there was a word operator)

use atoi() it's in stdlib.h

untested example

#include <iostream.h>
#include <stdlib.h>

int main()
{
  char str[50];
  int num;
  cout << "Enter your number:  ";
  cin >> str;
  num = atoi(str);
  cout << "\nYour number is " << num;
  return 0;
}

That should work.
