| clearBuffer() anyone can give me any help?? I have no clue how to do this...i just know that i get a 'bus error' otherwise.. Code:
void getBet(int* currentBet) {
int bet = 0;
for(printf("Enter Bet:\n"); 1; printSeparator()) {
scanf("%d", &bet);
// clearBuffer();
if ( bet <= money && (bet % 5) == 0 && bet > 0 && bet <= 500 ) {
break;
}
printSeparator();
printf("Invalid BET, try again:\n");
}
money = money - bet;
*currentBet = bet;
}

| nope.... unless i'm using it at the wrong time??? Code: void getBet(int* currentBet) {
int bet = 0;
for(printf("Enter Bet:\n"); 1; printSeparator()) {
scanf("%d", &bet);
fflush(stdin);
if ( bet <= money && (bet % 5) == 0 && bet > 0 && bet <= 500 ) {
break;
}
printSeparator();
printf("Invalid BET, try again:\n");
}
money = money - bet;
*currentBet = bet;

| Oh great links quzah! Thank you. I really didn't get how to do such a thing... shame that it isn't part of a library, uh? |

| ok.. sorry, but I still need more information. How can I implement it to my code? Code:
void getBet(int* currentBet) {
int bet = 0;
for(printf("Enter Bet:\n"); 1; printSeparator()) {
scanf("%d", &bet);
if (fgets(buf, sizeof(buf), stdin)) {
fflush(stdin);
if ( bet <= money && (bet % 5) == 0 && bet > 0 && bet <= 500 ) {
break;
}
}
printSeparator();
printf("Invalid BET, try again:\n");
}
money = money - bet;
*currentBet = bet;
}

{
int c;
while( (c = fgetc( stdin )) != EOF && c != '\n' );
}

| money = money - bet; ==> money -= bet; fgetc(stdin) ==> getchar() |

| I stand corrected. I don't do alot of non-file stream IO ^__^ Tks for the input. The solution does seem...inelegant though...it is exactly what the FAQ suggests I know but still looks like a hack... |
