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 close the file.)
