Karel struct programming problem

Question

#include <iostream>

#include <string>

using namespace std;

const int MAX_ROW = 14;

const int MAX_COLUMN = 14;

enum Direction {

NORTH, EAST, SOUTH, WEST

};

struct Karel {

int row;

int column;

Direction facing;

string name;

};

void karelMove(Karel &karel){

// your code here

}

void karelTurnLeft(Karel &karel){

if (karel.facing == NORTH){

karel.facing = WEST;

} else if (karel.facing == WEST){

karel.facing = SOUTH;

} else if (karel.facing == SOUTH){

karel.facing = EAST;

} else if (karel.facing == EAST){

karel.facing = NORTH;

}

}

int main(){

Karel karel;

karel.row = 15;

karel.column = 0;

karel.facing = EAST;

karel.name = "Karel";

}

WHAT I HAVE TO TYPE IN- void karelMove(Karel &karel){

}

PLEASE HELP ME TO PUT A REQUIRED CODE IN THE BLANK SPACE!!!!!

Answer 1

Not sure how your grid is set up but you have to change row and column depending on the direction it is facing. You should also pass an integer which tells how many cells to move and also you will need to check

to make sure it does not go off the grid.

Also , you should declare constant MAX=14;

#define MAX (14)

Assuming row major, then:

Move ( int n)

{

switch (this.facing)

{

case NORTH:

{

row = (row>n) ? (row-n) : 0;

break;

}

case SOUTH:

{

row = ((row+n)

break;

}

case EAST:

{

col = (col < n) ? col-n:0;

break;

}

case WEST:

{

col = ( (col+n)

break;

}

}
