void flip(void)

	int face;	// declare face

	for(int toss=1; toss<=100; toss++)	// coin tossed 100 times
		face=1+rand()%2;	// generate randomly 1 | 2
	switch(face)	// switch face
	{
	case 1:
		++frequency1;	// increment heads
		break;
	case 2:
		++frequency2;	// increment tails
		break;
	default:
		cout<< "It should never get here:";	// default should never occur
		break;	// optional
	}	// exit switch
	
	cout<< setw(10) << "Face" << setw(13) << "Frequency" << endl;	// display results
	cout<< setw(10) << "Heads" << setw(13) << frequency1 << endl;
	cout<< setw(10) << "Tails" << setw(13) << frequency2 << endl;
}

I am using microsoft visual c++ compiler. It only gives me 0 for heads and 1 for tails. Should it not give random values, I mean some times 0 for tails and some times 1 for heads. The program should toss the coin 100 times and should give each frequency 50 cus equal number of 1's or 0's for tails and heads generate. I dont understand this output. Should I be using srand() and seed thing?

for(int toss=1; toss<=100; toss++) // coin tossed 100 times
face=1+rand()%2; // generate randomly 1 | 2

You need more braces - without them, it's only this much code which is repeated 100 times.
The switch statement is executed just once.

Thanku Salem.
