Thread: Printing Array help

My new problem:
Ok, I think I am doing this right. How do I get it to print the new array after I have changed the element to the guest initial?

EDIT: Also I know that I am probably not doing this the best way possible, but I have to do it the way I know how, I want to understand what I am doing, and this is just the way I work it out.

This is what I have:

Code:

#include <stdio.h>
#define ROWS 4
#define COLUMNS 2

#include <stdio.h>

void printArray(int a[][2]);
void modifyElement(int e, char guest);

int main()
{
	int table[ROWS][COLUMNS]={1,2,3,4,5,6,7,8};
	int seat;
	int r;
	int c;
	char guest, junkChar;

	printArray(table);
    getchar();

	printf("In which seat would you like to place a guest?\n");
	scanf("%d",&seat);

	scanf("%c",&junkChar);
	printf("What is the initial of the guest you would like to place in this seat?\n");
	scanf("%c",&guest);

	switch(seat){
	case 1:
		r=0;c=0;
		break;
	
	case 2:
		r=0;c=1;
		break;
	
	case 3:
		r=1;c=0;
		break;
	
	case 4:
		r=1;c=1;
		break;
	
	case 5:
		r=2;c=0;
		break;

	case 6: 
		r=2;c=1;
		break;

	case 7:
		r=3;c=0;
		break;

	case 8:
		r=3;c=1;
		break;

	default:
		printf("You have entered an invalid seat number, please restart program.\n");

		return 0;
		break;
	}
	
	modifyElement(table[r][c],guest);

	
	return 0;

}

void printArray(int a[][2])
{
	int i;
	int j;
    printf("\t_____U____\n");
	for(i=0;i<=3;i++) {

		for(j=0;j<=1;j+=2){
			printf("\t%d|\t|%d\n",a[i][j],a[i][j+1]);
		}

	}
	printf(" \t----------\n");
}

void modifyElement(int e, char guest)
{
	
	e = guest;
	
}

ORIGINAL POST (already figured out):
How would I write a function to print an array that looks like this:

__U__
1| |2
3| |4
5| |6
7|___|8

I am able to get the array, but dont know how to get the lines.

Thanks in advance for any input.

EDIT: Its actually supposed to look like a rectangular table with columns 1,3,5,7 and 2,4,6,8. I dont know why I cant make it look right in this post.
