Chapter 6.2, Problem 20STE

Write the definition for a void function called toScreen. The function toScreen has one formal parameter called fileStream, which is of type ifstream. The precondition and postcondition for the function are as follows:

  //Precondition: The stream fileStream has been connected

  //to a file with a call to the member function open. The

  //file contains a list of integers (and nothing else).

  //Postcondition: The numbers in the file connected to

  //fileStream have been written to the screen one per line.

  //(This function does not dose the file.)
