hey
I would see on the screen like that UNDER THE mınumum array IT SHOULD WRITE MAX OR MIN WHATEVER YOU CHOOSE for example
if we write 2 arrays 3.4 5.6 0.6 8.6
it must write on the screen
" Arrays 3.4 5.6 0.6 8.6" MIN MUST WRITE UNDER 0.6 ( the minumum array )


it must work as well on Maximum also can anyone add that codes ?

you need to validate the value of arr_siz entered on line 26. What happens to your program if I enter 1000 on that line? Or if I enter a negative value ? Your program will die a very quick and ugly death.

>>it must work as well on Maximum also can anyone add that codes
Looks to me like it already does that.

Oufcourse it needs some protection codes like if you enter negative or 1000 but they are easy to put ,the major problem was that ablr to write "MAX OR MIN"under maximum or minumum values...I think ive already done it also, it works now !
