Question

c++ I am getting errors that say "expected a declaration". can you explain what it means by this and how I need to fix it?  

#include <iostream>
using namespace std;

//functions
void setToZero(int board[8][8]);
void displayBoard(int oboard[8][8]);
void movingFunction();

int main()
{
   // chess board 8x8
   int board[8][8];

   // all of the possible moves of the knight in 2 arrays
   int colMove[8] = { 2, 1, -1, -2, -2, -1, 1, 2 };
   int rowMove[8] = { -1, -2, -2, -1, 1, 2, 2, 1 };

   int row = 0; // starting row
   int col = 0; // starting column
   int newRow = 0; // transition row
   int newCol = 0; // transition column
   int mover = 1; // position # / tracker increase by 1 everytime a new position is found

   // function to set values to 0
   setToZero(board);

   board[row][col] = 1; // starting position in top left set to one

   bool ableToMove = true; // set to true so that while loop always executes

   // function to decide where knight will move
   movingFunction();

   // function to display board
   displayBoard(board);

   cin.get();
   cin.get();
   return 0;

}

//function to initialize to zero
   void setToZero(int fboard[8][8])
{
   for (int i = 0; i < 8; i++)
       for (int j = 0; j < 8; j++)
           fboard[i][j] = 0;
}

//function to display the board
void displayBoard(int oboard[8][8])
{
   int i, j;
   for (i = 0; i < 8; i++)
   {
       for (j = 0; j < 8; j++)
       {
           cout << " " << oboard[i][j] << " ";
       }
       cout << " " << endl;

   }

}

// function that enables knight to move
void movingFunction();
{
   while (ableToMove)
   {
       ableToMove = false;

       for (int i = 0; i < 8; i++)
       {
           for (int j = 0; j < 8; j++)
           {
               newRow = row + rowMove[i];
               newCol = col + colMove[j];

               // ensures that knight is staying on the board
               if (newRow >= 0 && newRow < 8 && newCol >= 0 && newCol < 8 && board[newRow][newCol] == 0)
               {
                   ableToMove = true; // becomes true if able to move
                   break;
               }
           }
           if (ableToMove == true)
           {
               break;
           }
       }
       if (ableToMove) // if became true, values are changed and "mover" (knight) increases

       {
           row = newRow;
           col = newCol;
           board[row][col] = ++mover;

       }
   }
