How to Generate Random Numbers

From Forum Nokia Wiki

Following Code snippet shows "How to generate random numbers" with Symbian C++ programming.

const TUint KRandomNumberSize = 6;

TBuf<KRandomNumberSize > CYrAppUi::GenerateRandom()
{
	TBuf16<KRandomNumberSize> random(_L(""));
	//Generate the random number of 6 Digits
	TInt i;
	for (i=0; i<KRandomNumberSize ; i++)
	{
		TInt num = Math::Random() % 10;
		TBuf<1> nTmp;
		nTmp.Num(num);
		random.Append(nTmp);
	}
	return random;
}

Use it as below:

TBuf<KRandomNumberSize> random(GenerateRandom());

Thus random descriptor will have 6 digits random number. User can change the value of KRandomNumberSize according to his/her needs.

Note: Do not forget to include e32math.h
