maze problems

**thaer89** · 11-20-2007

i have to do maze
but have this proplem

Code:

#include <stdio.h>
#include <lab6.h>
#include <unistd.h>

int main()
{

	int i;
	int j;

	for(i=0;i<20;i++)
	{
	for(j=0;j<50;j++)
	{
	printf("&#37;c",maze1[i][j]);
	}
	printf("\n");
	}


	}

the lab6.h have maze shape
i know how to draw it
but the problem i dont know how to make "c" in it
and know how to move C but first i need to know how to make it in maze without use "define" i need simple solution
please help

can i make the maze always repeat print it
when i move c

The first problem is a complete lack of any declaration for maze1.

Remember, lab6.h is something only you have.

**thaer89** · 11-20-2007

Code:

#include <stdio.h>
#include <lab6.h>
#include <unistd.h>




void dis (int k,int l)
{
	int j;
	int i;


	for(i=0;i<20;i++)
	{
		for(j=0;j<50;j++)
		{
			if(k==i && l==j)
				{
					maze1[i][j]='C';
				}
			
			printf("%c",maze1[i][j]);

		}
	printf("\n");
	}
}



int main()
{
	int k=18;
	int c;
	int l=0;
	int w=1;
	dis(k,l);

	while(w=1)
	{
			c=getchar();
		  	getchar();

		  switch(c)
		  {
		  	 case 'u':
				  k=k-1;
				  dis(k,l);
				  break;

			 case 'd':
				  k=k+1;
				  dis(k,l);
				  break;
			 case 'l':
				  l=l-1;
				  dis(k,l);
				  break;
	   		 case 'r':
				  l=l+1;
				  dis(k,l);
				  break;
			}
	}
	return 0;
}

this last thing i do it
now i can make "C" not to repeat in every new frame or new maze draw
and make clear screan

I guess you'll have to "remove the C" in the previous location, before you place it in the new location.

Also, you don't need to repeat the dis(l, k) in every case-block, just stick it after the end of the switch.

And you need to check the range of l and k so that you don't stomp outside the maze somehow.

i know this but how do it
and how to clear screen

You don't need to clear the screen, you just need to NOT store every C location inside your maze.

One alternative is of course to just print the C instead of your maze content.

this link for lab6.h
http://cs111.gju.edu.jo/labs/Lab6.h

**matsp** · 11-20-2007

That's certainly not how I meant. If you must be doign it that way, perhaps creating a function that takes the current and old position as parameters would be a good idea - you are repeating essentially the same code 5 times in your code.

but u i dont know how and the proplem now how to make appear one C not two C

The you have two choices:
1. Think about how you would do it.
2. Leave it as it is.

You really don't have to do anything different from what you are doing right now - except use a function to draw the maze. If you make it a separate function to modify the maze (put a C in a new place) it probably makes it easier, rather than doing that as part of the draw function.

i know why right two c because (j-1) was drawing before my if

**matsp** · 11-20-2007

Ok, that's good.

However, there are two things about all variants of your code like this one:

Code:

			  l=l+1;
				for(i=0;i<20;i++)
				{
					for(j=0;j<50;j++)
				{


				if(k==i && l==j && maze1[i][j]!='#')
					{
						maze1[i][j]='C';
						maze1[i][j-1]=' ';
					}


				printf("%c",maze1[i][j]);
				}
				printf("\n");
				if(maze1[k][l]=='#')
					{
						l=l-1;
					}

1. You check if you hit a wall AFTER you've modified the position, and then back off - which is wrong.
2. You are repeating a LARGE portion of code in 5 different places, which actually doesn't have to be repeated at all.

last version no error but i want to take character without enter
and clear screen i can do it in Linux because not work in windows
any body know how to make it small with void function with out change any thing because i try but i cant do it because if statement for not move from wall and dont repeat 'c'
and how make computer do it with self it hard
sorry for this

**matsp** · 11-20-2007

Right, reading characters from the keyboard without hitting enter is non-portable, and non-trivial.

I think you should start by concentrating on getting your maze-drawing into a function, and not repeat 5 x 15 lines of code.
