Fatal errors?

[medinal]

I'm getting a fatal error: fatal error LNK1120: 2 unresolved externals.
Also I know that my code won't work as it should as well, nut I want to figure out the issues in it, but I can't because of these errors.. I'm new, so I'm sorry for any of my ignorance in advance.


#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;

void PrintHeader(void);
void PrintTurnSeparator(void);
int RollDice();
int Move(int, int);
void PrintOneMove(string, int, int, int, int);
bool Win(int, int);
int CheckChutes(int);
int CheckLadders(int);
void GetPlayerNames(string &, int);

int main()
{
string name1, name2, name;
bool playagain;
int p1 = 1, p2 = 82, distance, position, die, turn, newPosition, diceRoll;

do
{
GetPlayerNames(name1, 1);
GetPlayerNames(name2, 2);
PrintHeader();
PrintTurnSeparator();
diceRoll = RollDice();
Move(position, diceRoll);
PrintOneMove(name, turn, position, die, newPosition);

} while (playagain != false);

system("pause");
return 0;




}

"Unresolved external" usually means that you are trying to call a function that you never gave a body to. The error message itself should actually tell you which function it is.

Can you post the actual error message instead of just summarizing it?

I bolded what I believe to be the problem, I'm just not sure how I'd go about resolving this.

Ah, yep. See the function is "RollDice". It's telling you that it can't find the body for that function.

And that's because there is no body!

Instead... you gave a body to "rollDice" (note the lowercase 'r').

Jesus... lol Thank you so much. Silly little errors.. lol
