C++ 2Dimensional array - c++

Question

I'm currently learning c++,and the code went so far,until
i made array variables to call a function instead of string,but something went wrong,and i can't figure out what it is.Problem is,it couts correctly only first 2 letters,then it couts the rest as └└└└ symbols.
Here's the code:
#include <iostream>
#include <string>
#include <windows.h>
#include <conio.h>
using namespace std;
int land(){
HANDLE hConsole;
hConsole = GetStdHandle (STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_GREEN);
char H = 72;
cout<<H;
}
int player(){
HANDLE hConsole;
hConsole = GetStdHandle (STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE);
char X = 88;
cout<<X;
}
/*previously,i declared a string inside worldgen,and generated 2d array inside the for loop,but when i changed variables to call a function,first letters were X and H,but then it went └└└└└└└└└└└└└└└└└└└└└└└ for all the remaining characters.What's wrong here? */
int worldgen(int dimX,int dimY,int x,int y){
HANDLE hConsole;
hConsole = GetStdHandle (STD_OUTPUT_HANDLE);
system("TITLE MyTitleText");
int H = land();
int X = player();
string world[dimX][dimY];
for(int c = 0;c<dimY;c++){
for(int count = 0;count<dimX;count++){
world[count][c] = H;
world[x][y] = X;
cout<<world[count][c];
}
cout<<endl;
}
}
int main(){
HANDLE hConsole;
hConsole = GetStdHandle (STD_OUTPUT_HANDLE);
worldgen(70,15,10,10);
cin.get();
}

Answer 1

Neither land() nor player() return anything so neither H nor X are getting any meaningful data are are just garbage data that was uninitialized.
I'm surprised this is even compiling since you have two functions that are supposed to return ints but aren't set to return anything.
