    You basically have the code down, You can use the for loop like you have above, except instead of printing the values you can scan them in.

    EDIT: I might have understood your question wrong, but if you are asking if the user can make the array bigger? Then the answer is no, not with your statically allocated array. You could possibly make your array larger if you used a dynamic allocation approach and then copied over the original array to the new larger one.

    thanks you
    i have done this part by using the loop function.using loop function for requesting user to input the integer and show these numbers by using the loop function.
