Program in C crashes after the 2nd input is requested

Question

I am new to the C language and I know there are a few Q&A out there about program crashes, but I think in this case my one is a bit specific and would prefer to make the question. I am attempting a Poker game and after running the program it crashes after I enter the "Y" or "N" command. I would appreciate any insights on how to solve this. Here's the code:

#include <stdio.h>
#include <time.h>
#include <ctype.h>
#include <stdlib.h>

#define FALSE 0
#define TRUE 1

void printGreeting();
int getBet();
char getSuit(int suit);
char getRank(int rank);
void getFirstHand(int cardRank[], int cardSuit[]);
void getFinalHand(int cardRank[], int cardSuit[], int finalRank[],
                  int finalSuit[], int ranksinHand[],
                  int suitsinHand[]);
int analyzeHand(int ranksinHand[], int suitsinHand[]);

main(void) {
    int bet;
    int bank = 100;
    int i;
    int cardRank[5];
    int cardSuit[5];

    int finalRank[5];
    int finalSuit[5];
    int ranksinHand[13];
    int suitsinHand[4];
    int winnings;
    time_t t;
    char suit, rank, stillPlay;

    //print greeting
    printGreeting();

    // plays a new hand of draw poker

    do {
        bet = getBet();
        srand(time(&t));
        getFirstHand(cardRank, cardSuit);
        printf("Your five cards: \n");

        for (i=0; i<5; i++) {
            suit = getSuit(cardSuit[i]);
            rank = getRank(cardRank[i]);
            printf("Card #%d: %c%c\n", i+1, rank, suit);
        }


        for (i=0; i<4; i++) {

            printf("Card #%d: %c%c\n", i+1, rank, suit);
        }

        winnings = analyzeHand(ranksinHand, suitsinHand);
        printf("You won %d!\n", bet*winnings);
        bank = bank - bet + (bet*winnings);
        printf("\nYour bank is now %d.\n", bank);
        printf("\nDo you want to play again? ");
        scanf(" %c", &stillPlay);
    } while (toupper(stillPlay) == 'Y');

Answer 1

You have forgot & inside scanf in line number 276, So use this:

scanf(" %c", &ans);

instead of

scanf(" %c", ans);
