Need help assigning random numbers to characters

I need help assigning numbers generated to characters. This code should produce a 0 or 1 and I want 0 to equal A and 1 to equal B.

1
2
srand(static_cast<unsigned int>(time(0)));
	coin_flip = rand() % 2;
Don't know if I got the question right, but why don't you simply declare a char variable and use an if? Something like

1
2
3
4
5
char c;
if(coin_flip == 0)
    c = 'A';
else
    c = 'B';
