Simple turtle problem

Hi Guys

I have decided to make my own version of the turtle logo graphics program but and I have simplified it by removing the turn left and right commands. Instead the user enters the amount of movements they wish to make and then enter the x and y coordinates for each movement.

It compiles ok but when I attempt to go outside of the boundarys of the array I am getting a seg-fault ( which i should do ) but it is not reading the if statement.

Here is my code

Code:

---

#include <iostream>
#include <string>

// function prototypes
int mainMenu ( char[][ 20 ] );
std::string raisePenUp ( bool& );
std::string lowerPenDown ( bool& );
void moveTurtle ( char[][ 20 ], bool& );
void printArray ( char[][ 20 ] );

// main function - driver //////////////////////////////////////////////////////
//
int main ( void )
{
  const int MAX_ROW = 20;
  const int MAX_COL = 20;
 
  char floor[ MAX_ROW ][ MAX_COL ] = {{ 0, 0 }};
 
  mainMenu ( floor );
 
  std::cin.get(); // freeze console output window
 
  return 0; // return value from int main
}

// function to display the main menu
int mainMenu ( char flr[][ 20 ] )
{
  // pen position. True is raised up False is lowered down
  bool penPosition = true;
 
  int choice = true;
 
  do
  {
      std::cout << "\tMain Menu\n\n"
                << "Enter 1 to raise the pen up\n"
                << "Enter 2 to lower the pen down\n"
                << "Enter 5 to move the turtle\n"
                << "Enter 6 to print the array\n"
                << "Enter 9 to quit the program\n\n"
                << "> ";
      std::cin >> choice;
     
      switch ( choice )
      {
      case 1:
        std::cout << raisePenUp ( penPosition );
        break;
       
      case 2:
        std::cout << lowerPenDown ( penPosition );
        break;
       
      case 5:
        moveTurtle ( flr, penPosition );
        break;
       
      case 6:
        printArray ( flr );
        break;
       
      case 9:
        return 0;
        break;
       
      default:
        break;
      }
  } while ( choice );
}

// function to raise the pen upwards so the turtle can
// move freely along the board
std::string raisePenUp ( bool &rPp )
{
  std::string str1 = "The pen has been raised up...\n\n";
  std::string str2 = "The pen is already rasied up!\n\n";
 
  if ( rPp == true )
  {
      return str2;
  }
 
  else if ( rPp == false )
  {
      rPp = true;
     
      return str1;
  }
}

// function to lower the pen down so the turtle can
// draw the shapes onto the board
std::string lowerPenDown ( bool &rPp )
{
  std::string str1 = "The pen has been lowered down\n\n";
  std::string str2 = "The pen is already lowered down!\n\n";
 
  if ( rPp == false )
  {
      return str2;
  }
 
  else if ( rPp == true )
  {
      rPp = false;
     
      return str1;
  }
}

// function to move turtle
void moveTurtle ( char flr[][ 20 ], bool &rPp )
{
  int xCoord = 0;
  int yCoord = 0;
  short totalMoves = 0;
 
  if ( rPp == true )
  { 
      std::cout << "\nYou cannot draw while the pen is raised up\n\n";
  }
 
  else if ( rPp == false )
  {
      std::cout << "\n\nHow many moves will the turtle make?: ";
      std::cin >> totalMoves;
     
      for ( int i = 0; i < totalMoves; i++ )
      {
        std::cout << "Enter x coordinate for movement " << i << ": ";
        std::cin >> xCoord;
       
        if (( xCoord < 0 ) || ( xCoord > 20 ))
        {
            std::cerr << "\nPlease keep within 0 - 20\n";
           
            std::cout << "Enter x coordinate for movement " << i << ": ";
            std::cin >> xCoord;
        }
       
        std::cout << "Enter y coordinate for movement " << i << ": ";
        std::cin >> yCoord;
       
        // this is being ignored by the program
        if (( yCoord < 0 ) || ( yCoord > 20 ))
        {
            std::cerr << "\nPlease keep within 0 - 20\n";
           
            std::cout << "Enter y coordinate for movement " << i << ": ";
            std::cin >> yCoord;
        }
       
        flr[ xCoord ][yCoord ] = '#';
      }
  }
}

// function to print the array showing the patterns made by
// the turtle controlled by the commands from the user
void printArray ( char flr[][ 20 ] )
{
  for ( int i = 0; i < 20; i++ )
  {
      for ( int j = 0; j < 20; j++ )
        std::cout << flr[ i ][ j ];
        std::cout << std::endl;
  }
}

Don't worry I solved the problem. I changed "if" to "while" so it looped untill the input was inside the array bounds.

It's not being ignored, as far as I can tell; if you enter a number out of bounds you get one chance to fix it (since it's an if, not a while).
