Maze game error

[zamychu]

Hey, I'm pretty new at this and I have this maze game I'm making on C++, and every time I try to run it whilst debugging, the same 3 problems come up with the enemies I've implemented.
The error message states; 'Run-Time Check Failure #3 - The variable 'Enemy1' is being used without being initialized.'
it does the same for Enemy2 and Enemy3.
i was wondering if anyone could tell me what I'm doing wrong?
the code is as follows;

#include <iostream>
#include <cstdlib>
//#include <ctime>
using namespace std;

struct Killer{
int x, y;
char kill;
};

struct Blocker{
int x, y;
char block;
};

struct Restarter{
int x, y;
char restart;
};

const char Height = 11, Width = 18;
const char Player = 'O', enemy1 = 'K', enemy2 = 'B', enemy3 = 'R', Goal = 'X';
int playerPositionX = 1, playerPositionY = 1, goalPositionX = 10, goalPositionY = 16;
char playerMovement;

unsigned char Map[Height][Width] = {
'#','#','#','#','#','#','#','#','#','#','#','#','#','#','#','#','#','#',
'#',' ',' ',' ','#',' ',' ',' ',' ',' ',' ',' ',' ',' ',' ',' ',' ','#',
'#',' ','#',' ','#',' ','#','#',' ','#','#','#','#','#','#','#',' ','#',

main.cpp(58): warning C4700: uninitialized local variable 'Enemy1' used
main.cpp(77): warning C4700: uninitialized local variable 'Enemy2' used
main.cpp(96): warning C4700: uninitialized local variable 'Enemy3' used

It means that the variables have a random value. Random values can lead to problems that are difficult to find.

Oh right, thanks so much
How would you suggest I correct this?

Initialize them. Set their game state. Set their position. Otherwise all you get is garbage values.
