drawing a 2d array

ok im makeing a game and the maps are 80 accross 15 down and the only way i can think of drawing it is with a lot of
couts or with alot of loops but i cant get the loop idea to work any have some sample code from an old program basicly its like if it is 0 draw the floor if it is 1 draw the wall.

i don't have any sample programs, but it sounds like relatively easy iterative program, the idea lies in the logic, have a nested (double) loop , first one iterates 15 times and the inner loop iterates 80 times, and within the inner loop make a conditional check....

Code:

   if(x == 0) cout << something;
   
  else if(x == 1) cout<< somthingelse;

hope this can get you started.....

try to start on your own if you get stuck then post some code and we'll try to help you..

good luck...

here is a tip..

use a 2d array like map [5][5]

Code:

then say map[5][5] = { 1, 0, 1, 0, 0, 1, 0, 0, 1, , 0};
   for ( row =0; row <= 4; row++ )
   {     
         for ( col =0; col <= 4; col++ )
           if ( map[row][col] == 1 )
           //print *
           else
   }        //print " "

Those work, but as you've got a rather large map, consider putting it in a text file. You could make '-'s be grass and then '~' be water. Then, you could load the file, and based on the character it reads, it could draw a certain character. Here's some minimal code. It will load up a file, assign some values into a map[][] array based on the characters on the file, and then print the map:

Code:

#include <fstream.h>
#include <stdio.h>

int map[80][15];
#define GRASS 1
#define WATER 2

...

void Map()
{
     int i;
     int j;
     ifstream fmap("map.txt");

     char str[1200]; // That's a big array but it needs to go through the file

     for(i = 0; i < 15; i++)
     {
          fmap >> str;
          for(j = 0; j < 80; j++)
          {
                switch((int)str[j])
                {
                case '-':
                     map[j][i] = GRASS;
                     break;
                case '~':
                     map[j][i] = WATER;
                     break;
                }
           }
     }

     fmap.close();

     // Now show the map
     char tile = (char)176;
     HANDLE std = GetStdHandle(STD_OUTPUT_HANDLE);

     for (i = 0; i < 15; i++)
     {
          for (j = 0; j < 80; j++)
          {
               switch(map[j][i])
               {
               case GRASS:
                    gotoxy(j,i);
                    SetConsoleTextAttribute(std, F_D_GREEN | B_GREEN); // For simplicty's sake, pretend I have all the colors pre-defined as these
                    printf("%c", tile);
                    SetConsoleTextAttribute(std, F_GREY | 0); // I like changing the text back to grey
                    break;
               case WATER:
                    gotoxy(j,i);
                    SetConsoleTextAttribute(std, F_BLUE | F_GREEN | B_BLUE);
                    printf("%c", tile);
                    SetConsoleTextAttribute(std, F_GREY | 0);
                    break;
               }
          }
     printf("\n");
     }
}

That's some basic code. Hope that helps a little.
