    //read in the first line of the file

    //initialize largest and smallest
largest = input;
    smallest = input;

    while( ! infile.eof()) //process each line untilend-of-file is reached

        *** Your code here***

         infile >>input; //get the next line

Explanation / Answer

x.P5e is the answer for the question you asked for it reads in a set of numbers of int, and outputs the smallest and largest numbers to the screen. To help you to get the smallest and largest is when you first get your first integer set that integer equal to the smallest and largest. That way each number is compared to that number. And if their is a number that is larger or smaller set that integer to the smallest or largest. It also contains a function for the introduction of the program what it is about to do.
