    Right, the way it works here is that you TRY something, then ask for help showing what you have done in the source code.

    Suppose I, being as generous as I am , give you a bag of coins and ask you to find the largest (or smallest) denomination (value) among the coins. How would you do it?

    Create a couple variables to store the highest and lowest values. Initialize the "high" variable to an extremely small value and update it if necessary as you enter in each new value... if the new value entered is more than what is already stored, then change the "high" variable to match the current new value. Do something similar for the "low" variable, initialize it to something really high and then keep testing/comparing it against the new values being entered and update if needed. It's really simple.

    That is not the point. I am trying to get you to come up with an algorithm.

    hk_mp5kpdw has provided you with a possible algorithm, though personally I do not find it intuitive. (When we compare stuff, we typically do not start by comparing the first item with some imaginary extreme value. Rather, we start by comparing the first item with the second item.)

    is looping involve in this?

    i know how to display the highest and the lowest but in a limited manner

    for example 10 items,

    will i could get it since i could manually compare the 1st number up to the last

    but with 100 items hehehehe i could still manually do that but im looking for a better program

    which could easily compare the highest and the lowest

    Ah, so that is what you mean by "manual": hardcoding the comparisons.

    Yes, you should use a loop.

    Whenever you need to do something repetitively some number of times, looping is always involved.

    The main idea here is to deal with largest-so-far and the current number. Is the current number we're looking at right now the largest number? If so, make a note. If not, we don't care.

    Yes. As I noted, you already have an algorithm outlined to you that uses a loop to do what you want to do.
