simple array code

[earlrainer]

in delphi how do i make an array of integers, fill it with random numbers and then find the max from these numbers?

thanks

It's all in the Delphi help files. You just need to string the various functions together. If you get stuck with something specific then post back and we will be glad to help.

Here are some pointers:
Arrays: work out whether you need a static (fixed-size) or dynamic (variable-size) array and read the Delphi help for examples of how to implement either.

Randomization: to generate random numbers to place in the array check out Delphi's Randomize and Random functions.

Max: to find the highest random number in the array, use Delphi's Max function within a loop.

This sounds awfully much like a homework assignment.

Yeah, but he's been at it for 5 years so he really needs the help!

On the off-chance it's not a homework assignment, I'd just inspect each random number before you add it to the array and keep track of the largest one. Forget about searching the array afterwards

I do agree with Griffyn's assessment. Inspecting a number stream for a maximum number is much more straightforward than trying to search an array afterwards for it.

I'm sure EarlRainer will come up with the answer of this for us. But I'd be surprised if it wasn't a homework assignment - it's just too simple of a problem to not have appeared there (actually I did this one in a class once).

thanks for your replies guys.
just been way out of touch with delphi.
actually what i was looking for is if a DLL passes me a dynamic array with X values , what function do I use to find X. I thought it was hi-lo but guess its not

 

[Stretchwickster]

Use the Length function to find the size of the array. Use Low and High functions as the lower and upper bounds of the for loop.
