I would do something like:
bool* pBool = boolArray + 10; srand( (unsigned)time( NULL ) ); for (int i = 0; i < 10; ++i) {
memset(pBool, 1, sizeof(bool) * 12); int rIndex = rand() % 12; pBool[rIndex] = 0; do
{
int rIndex2 = rand() % 12; pBool[rIndex2] = 0; } while (rIndex2 == rIndex);
pBool += 12; }
I have not tested this so you need to try it a few times to make sure it produces the desired results.

Did you really think that it's necessary to dump your entire unformatted code base here and expect us to guess where you are getting this error message?
[Edit]
You have several problems going on here. You have many for statements that are simply
for (i = 0; i>cde; a couple of which appear to have no purpose.
Your nested class declaration is incomplete.
Your include statements are missing.
You are declaring functions inside other functions.
This has nothing to do with C++/CLI
probably others.

Well, thanks for bringing it to my notice.Actually when I copied it into the editor on the website, it looked fine, but after submission edges of the statements were cropped off so was the formatting
 like the one u mentioned.I am not able to submit the complete statements.
|
|
|
|

You forgot the closing brace after function BILLS::enter(). If you formatted your code properly you would be able to spot such errors quite easily.

We still don't provide code to order. You will have to either develop it yourself or resort to another site where you can hire developers. If you decide to develop it yourself and you encounter a specific problem, we'll probably be able to help. You've been told this before - please stop posting instructions.

DON'T SHOUT! 
Typing everything in upper-case on the Internet is considered extremely rude.
This is now the second time you've posted exactly the same instruction - presumably from your homework assignment - in this forum. Whilst the unpaid volunteers who answer questions here will be happy to help if you encounter a specific problem with code you've written, nobody here is going to write your code for you.

When i try to add a Dll file into the project ,using Add Reference-->under properties .The Dll file was created VC6.
The followwing error was shown Could not add reference: ..\..\\
for one of the reasons , -Targets a higher of the.net framework
-Not a.Net assembly, -Not a registered ActiveX control
suggest how to use the dll in the project
|
|
|
|
|
The error message is telling you the reason. The DLL created in VC6 is not a .NET assembly.
If you want to use it in your project, you will have to use P/Invoke.
EDIT:
Since this is the C++/CLI forum, I forgot to mention that you can also call the DLL functions directly from C++. But there is no way to add it as a .NET reference.
The difficult we do right away...
...the impossible takes slightly longer.

With the new open source .Net implementation is there an open source implementation of C++\CLI?
|
|
|
|
|
Not sure exactly which part of .NET you're asking about but they are not open-sourcing the C++/CLI compiler.
|
|
|
|
|
I am pretty sure that it's just ASP.NET 5 that is going open source. I have not heard about anything else.
