help on craps

[nemesis]

help!!!
IMy problem is that I don't know how to make the increase/decrease part work.
The specification given to me by my teacher was: if the layer wins, double the wager (done!), and if loses , decrease the wager by the value entered by the player(done also!).
fot each continuation of the game, the player must be asked if he wants to increase/ decrease the wager, he must enter a new value. otherwise the wager remains the same. (I can't do that! Pls. help me!).

here's my code (pardon my code for being messy.. and i think my functions are all wrong.. :( )

getch();
printf("Rolling a dice...\n");

srand((unsigned)time(NULL));

printf("\nThe spot on the first dice is:");
random1 = (rand()%6)+1;
cout << random1 << endl; }

printf("The spot on the second dice is:");
random2 = (rand()%6)+1;
cout << random2 << endl; }

return (random1+random2);
