.NET Forum / .NET Framework / New Users / September 2007creating simple array... how to?
I'm trying to create a simple 2-dim array of integers, but don't know how to do that... in definition of class, I wrote: int *results; while in constructor: results = new int[256][256]; but, I got an error: C2440: '=' cannot convert from int{*}[256] to 'int *'. what is wrong? > I'm trying to create a simple 2-dim array of integers, but don't know how > to do that...

Try this instead: I'm assuming C++, as you don't specify. int x[][] = new int[256][256]; The reason your attempt does not work is because a pointer to int is not the same as an array name, although the array name (once the array is properly declared) can be used as a pseudo-pointer to the array. >> I'm trying to create a simple 2-dim array of integers, but don't know how >> to do that...

Well, the reason is the same as the person posted as "PvdG42" says, but you want the managed C++ syntax instead. Here's the doc page that can help you with that: http://msdn2.microsoft.com/en-us/library/fkzha470.aspx >>> I'm trying to create a simple 2-dim array of integers, but don't know >>> how to do that...
