unresolved external symbol

class Character{

public:

    int getXCoord();
    void setXCoord(int xCoord);

    int getYCoord();
    void setYCoord(int yCoord);

    int itsXCoord;
    int itsYCoord;

};
void Move(){
int move;
Character Hero;
Hero.setXCoord(0);
Hero.setYCoord(0);
cout << "You are at :" << Hero.getXCoord() << ", " << Hero.getYCoord() << endl;
cout << "1)North 2)South 3)East 4)West: ";
cin >> move;
if (move == 1){
    Hero.itsXCoord += 1;
}
if (move == 2){
    Hero.itsXCoord -= 1;
}
if (move == 3){
    Hero.itsYCoord += 1;
}
if (move == 4){
    Hero.itsYCoord -= 1;
}

cout << "Currently you are at: " << Hero.getXCoord() << ", " << Hero.getYCoord();
}

I keep on getting a

1>one.obj : error LNK2019: unresolved external symbol "public: int __thiscall Character::getXCoord(void)" (?getXCoord@Character@@QAEHXZ) referenced in function "void __cdecl Move(void)" (?Move@@YAXXZ)

error.

I don't know why.

Please help me!

You did not provide function bodies for getXCoord() or getYCoord(), or any of the set functions. Provide function bodies (a. k. a. function definitions).

[inform880]

What function definitions should be there?

[D80DSL3A]

You need to define what the functions do, like you have done for the Move() on lines 16-36.
Note: There is no need for set() and get()'s. The variables in your class have public access so you can use the values directly.
eg: instead of Hero.setXCoord(0);
You could assign directly: Hero.itsXCoord = 0;
