Need help Implementing maze into 2d array c++
So Im creating a treasure hunting game where the user moves through a maze with hidden health and traps. The goal is to find the treasure without dying. However, I need to create a map and I have a map I generated. I was wondering if there was a way I could just copy and paste my text based maze into the array without putting it in the main function and instead the drawMap function instead of filling each cell. Any help would be greatly appreciated. Thank you!

HANDLE console = GetStdHandle(STD_OUTPUT_HANDLE); // For use of SetConsoleTextAttribute()
// Function Prototypes
void titleScreen(); // Prints Title and instructions
void mapCreation( char arr[][12], int level);
void drawMap(char arr[][12]);
bool update(char arr[][12], int &level, int &lives, int &score);
// Main Program
int main ()
{
// initialize variables
int option;
char baseMap[12][12];
int level = 1;
int lives = 3;
int score = 0;
bool gameOver = false;
bool levelCompleted = false;
SetConsoleTextAttribute(console, 240); // change background to white
system("CLS");// clears screen in order to remove black background
titleScreen(); // Display Title
do // do-while loop starts
{
cin >> option; // take in input
if(option == 1) // temporary option to check for next screen
{
//Display Maze
system("CLS");// clears screen in order to remove black background
while(gameOver == false)
{
mapCreation( baseMap, level );
while(gameOver == false || levelCompleted == false )
{
drawMap(baseMap);
update(baseMap, level, lives, score);

You could define your mazes as 2D array of strings, stored as a global variable something like this:
#define LEVEL_COUNT (2)
const char* maps[LEVEL_COUNT][12] =
{
{
"||||||||||||",
"| | |",
"| | |",
"| |||| |",
"| |",
"| |",
"|||||| |",
"| | |",
"| | | |",
"| | |",
"| | |",
"||||||||||||",
},
{
"||||||||||||",
"| | |",
"| ||||| |",
"| | |",
"| |",
"| ||||",
"| |",
"| | |",
"| | |",
"||||||| |",
"| |",
"||||||||||||",
},
};
Then you can load them into your char array, setting spaces to zero:
void loadMap( char arr[][12], int level)
{
if((level < 0) || (level >= LEVEL_COUNT))
return;
for(int i = 0; i < 12; i++)
{
const char* row = maps[level][i];
for(int j = 0; j < 12; j++)
{
if(row[j] == 0)
break; // end of string
if(row[j] == ' ')
arr[i][j] = 0; // set spaces to zero
else
arr[i][j] = row[j];
}
}
}
Call loadMap from your mapCreation function after initializing to all zeros (in case any of the strings in the map array are less than 12 chars long and a terminating null is encountered), then apply your randomized traps and treasure placements.
e.g:
void mapCreation( char arr[][12], int level )
{
int traps = 0;
int lives = 0;
int treasure = 0;
int x;
int y;
for(int i = 0; i < 12; i++)
{
for(int j = 0; j < 12; j++)
{
arr[i][j] = 0;
}
}
// load the map:
loadMap(arr, level);
arr[1][1] = '1';
switch (level)
{
case 1:
while(treasure < 1)
{
x = (rand() % 10);
y = (rand() % 10);
if(arr[x][y] == '0')
{
arr[x][y] = 2;
treasure++;
}
}
// etc...
