Random

[Guest]

Can somebody help me out? I need the code to generate a random number between
1 and 100.

 

[Scott M.]

Dim randValue As Integer
Dim x As New Random
randValue = x.Next(1001)

The documentation on the Next method does not state the very important fact
that the value you pass as the maximum value the random class should return
(in this case 1001) is never reached. So, if you want to potentially get
back 1000, you must enter 1001.

Scott gave you VB code. Here's the C# equivalent.

Random myR = new Random();

int x = myR.Next(1,101);

The C++ code would depend on the type of project, i.e. the .NET Random class
would be appropriate in a .NET WinForms app, but not in a MFC app.

What language are you using?

back 1000, you must enter 1001.

However, the lower bound should be 0 here, so actually what's wanted is

x.Next(100)+1

(or x.Next(1, 101))
