Trying to finish this game

Hoggmeiser (5)
Hi everyone, I've been working on this game where you are placed into a location in a matrix, and you need to go up, down, left, or right to get to the solution. I'm calling it 'Forest Maze'. So pretty much I start at 7,4 --- and I need to make it to 3,2. I have it working so far, but when I finally land on 3,2 my 'winner()' function does not kick in. Here's my code...

/*Forest Adventure code. The user enters directions one after another until they escape the forest*/

#include <iostream>
#include <cmath>
#include <string>

using namespace std;

int forest[7][7] = {{0,0,0,0,0,0,0},
{0,0,0,0,0,0,0},
{0,1,0,0,0,0,0},
{0,0,0,0,0,0,0},
{0,0,0,0,0,0,0},
{0,0,0,0,0,0,0},
{0,0,0,0,0,0,0}};
string dir;
int userX = 4;
int userY = 7;
int userLoc = forest[userY][userX];

void winner()
{
cout << "Congratulations, you found the exit!" << endl;
cout << "Play again sometime!" << endl;
cout << "Press any key to exit...";
cin.get();
}

int movement()
{
if (dir == "U")
{
cout << "You went up one area. Is this the exit...?" << endl;
userY--;
if (userLoc == 1)
{
userLoc = 1;
return 0;
}
else
{
cout << "No exit here... (Currently: " << userY << ", " << userX << ")" << endl << endl;
cin.get();
return 1;
}
}
else if (dir == "D")
{
cout << "You went down one area. Is this the exit...?" << endl;
userY++;
if (userLoc == 1)
{
userLoc = 1;
return 0;
}
else
{
cout << "No exit here... (Currently: " << userY << ", " << userX << ")" << endl << endl;
cin.get();
return 1;
}

}
else if (dir == "L")
{
cout << "You went left one area. Is this the exit...?" << endl;
userX--;
if (userLoc == 1)
{
userLoc = 1;
return 0;
}
else
{
cout << "No exit here... (Currently: " << userY << ", " << userX << ")" << endl << endl;
cin.get();
return 1;
}

}
else if (dir == "R")
{
cout << "You went down one area. Is this the exit...?" << endl;
userX++;
if (userLoc == 1)
{
userLoc = 1;
return 0;
}
else
{
cout << "No exit here... (Currently: " << userY << ", " << userX << ")" << endl << endl;
cin.get();
return 1;
}

}
};

int direction()
{
cout << "Which direction would you like to go?: ";
cin >> dir;
movement();
return userLoc;
}


int main()
{
cout << "Welcome to Forest Adventure!" << endl;
cout << "You are lost in a forest, find your way out!" << endl;
cout << "Type U, D, L, R when prompted to select which direction"<< endl;
cout << "you would like to go! (U=Up,D=Down,L=Left,R=Right)" << endl;
cout << "Have fun!" << endl << endl;

do
{
direction();
}
while (userLoc != 1);

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

Any criticism is completely welcome, lots of redundant stuff going on here I think. Thanks in advance!!

You're using variable globals, you have no bounds checking, and an array starts at 0 not 1.

That being said, I assume this is probably one of your early games as you're just learning C++. Glad to see you're taking an initiative and aren't afraid to try things.

Things to research: using functions with variables, the cases of going out of bounds (when x or y is 7 or larger), and you're not actually using your array that you created.

Edit: I'm surprised it even compiles. Just looking at the variable userLoc, that should cause a runtime error. Also, changing the values of d and y will not change the values of userLoc.

Also, please be sure to use code tags. Highlight your code and click the <> button to the right.

Okie doke, I'll look into that. Thanks

It now compiles okay, but the winner() only triggers when I go to 3,2 instead of 3,3. Any ideas?
