c - Dice game program will not run but will not stop at 5 rolls

I am getting two errors:

Error 3 error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup

and:

Error 4 error LNK1120: 1 unresolved externals

Since I can not get the program to run, I am also unsure if Case 'A' will generate a roll or not. I don't want to display the results in Case 'A' and my gut feeling is scanf should not be there but I could be wrong.

Here is my code:

#include
#include
#include 
#include 

#define PAUSE system("pause")



int main ()
{
    int diceOne, diceTwo, diceThree;
    int currentDiceSum=0, totalDiceSum=0;
    char choice;
    int count = 0;

    srand((unsigned)time(NULL));


    diceOne      =rand()%6+1;
    diceTwo      =rand()%6+1;
    diceThree    =rand()%6+1;

    do {
        printf("\n Roll the dice, but you only get 5 rolls! You can't play forever, you know. \n");

        printf("Main Menu\n");
        printf("A.Roll the Dice\n");

        printf("B.Display the Result of Last Roll\n");
        printf("C.Quit\n");

        printf("Enter your choice:   ");
        scanf(" %c", &choice);

        choice = toupper(choice);

        switch(choice) {
            case 'A': 

                printf("Dice are rolled!'\n");

                diceOne      =rand()%6+1;
                diceTwo      =rand()%6+1;
                diceThree    =rand()%6+1;


                count ++;
                break;
            case 'B':  

                if (count = 0) {
                    printf("Please roll the dice atleast once\n");
                }  else {
                    printf("Dice 1: %d\n", diceOne);
                    printf("Dice 2: %d\n", diceTwo);
                    printf("Dice 2: %d\n", diceThree);

                    currentDiceSum = diceOne + diceTwo + diceThree;
                    printf("Dice Total: %d\n", currentDiceSum);
                    totalDiceSum+= currentDiceSum;

                }
                break;
            case 'C':
                if (count == 5)  
                    printf("Number of rolls: %d\n", count);

                printf("Total of all dice for all rolls:%d\n",totalDiceSum);
                printf("Goodbye, hope to see you again!!!\n");
                PAUSE;
                break;


            default:
                printf("Was not a valid menu choice (Please enter A,B,C\n");
                break;
        }
    } while (choice!= 'C'); 
}
