Why is the computer's input not being considered? - c

Question

In the code below there is an error I can't locate causing the computer's selection to not be accounted for. The user's input is being considered in the Nim game yet the computer's pieces are not being subtracted.
#include <stdio.h>
#include <stdbool.h>
#include <stdlib.h>
void printInstructions();
int getUserInput(int);
int randomRange(int,int);
int PlayerTurn(int);
int smartCompMove(int);
int dumbCompMove(int);
int main()
{
srand(time(NULL));
int pieceAmount = randomRange(12,24);
char smartCompOrDumb;
printf("Do you want to play a smart computer or a dumb one? Select 'S' or 'D'.");
scanf("%c",&smartCompOrDumb);
bool gameOver = false;
bool playerTurn = true;
printInstructions();
while(pieceAmount > 0 && gameOver == false)
{
if (playerTurn == false)
{
if(pieceAmount <= 4)
{
printf("\nThe Computer has won :P ");
gameOver = true;
exit(0);
}
if (smartCompOrDumb == 's' || smartCompOrDumb == 'S')
{
playerTurn = true;
pieceAmount = smartCompMove(pieceAmount);
printf("%d",pieceAmount);
}
else if (smartCompOrDumb == 'd' || smartCompOrDumb == 'D')
{
playerTurn = true;
pieceAmount = dumbCompMove(pieceAmount);
printf("%d",pieceAmount);
}
}
else
{
if(pieceAmount <= 4)
{
printf("\nYou have won :) ");
gameOver = true;
exit(0);
}
playerTurn = false;
pieceAmount = PlayerTurn(pieceAmount);

{

}
else
{
printf("This is not a valid move so try again.");
}
}
}
return pieceAmount;
}
int dumbCompMove(int pieceAmount)
{
int dumbPick = rand() % 3 + 1;
printf("\nComputer will pick from the stack. \n");
pieceAmount = pieceAmount - dumbPick;
printf("\nComputer picked %d pieces. \n", dumbPick );
return pieceAmount;
}
int smartCompMove(int pieceAmount)
{
int smartPick = 1;
printf("\nThe computer will select their pieces. \n");
if (pieceAmount >= 15 && pieceAmount < 24)
{
smartPick = 2;
pieceAmount = pieceAmount - smartPick;
}
else if (pieceAmount >= 10 && pieceAmount < 15)
{
smartPick = 4;
pieceAmount = pieceAmount - smartPick;
}
else if (pieceAmount >= 6 && pieceAmount < 10)
{
smartPick = 1;
pieceAmount = pieceAmount -smartPick;
}
else
pieceAmount = 3;
printf("\nThe computer selected %d pieces. \n",smartPick);
return pieceAmount;
}
I had this code working earlier yet somehow I must have altered something minor and now it will not function properly. I am using the Cloud9 program to run it.
