 help on craps
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.. :( )
[PHP]

#include <string.h>

printf("\nPress a key to roll a dice.\n");
getch();
printf("Rolling a dice...\n");
getch();
srand((unsigned)time(NULL));
for(dc1=0; dc1<1; dc1++) {
printf("\nThe spot on the first dice is:");
random1 = (rand()%6)+1;
cout << random1 << endl; }
for(dc2=0; dc2<1; dc2++) {
printf("The spot on the second dice is:");
random2 = (rand()%6)+1;
cout << random2 << endl; }
return (random1+random2);
}
int win(int total, int wager)
{
