I have entered 1,2 ,3,4,5.I should get maximum 5 and minimum 1 but I am getting minimum 2 Why?

Answer 1

Your first loop changes a(1), so the contents of the array have been changed. a(1) is no longer the minimum value.
Rather than changing a(1), create a separate variable, say "maxval" and use it to store the maximum value.

Plus, if you also create a "minval" name, you can scan for both max ind min in a single loop.
