Array help

Hi,
this is a school assignment and I am stuck.
I have 3 one dimensional arrays, I think 2 dimensional might be easier, but this is what the assignment calls for.

Now what I have is this:

Code:

main()
{
	int x = 0;
	int y = 0;
	int z = 0;
	int empnum[30]={1, 4, 5, 7, 8, 12, 13, 14, 16, 22};
	int days[30]={5, 8, 4, 5, 10, 5, 4, 10, 4, 4};
	int vehicles[30]={30, 40, 20, 30, 70, 10, 15, 20, 40, 50};
	
		printf("\n Employee #");
		printf(" Days");
		printf(" Vehicles\n");
  for ( x = 0; x < 10;x++ )
	{
	  printf("%8d ", empnum[x]);
		for ( y = 0; y < 10; y++ )
			{
				printf("%8d ", days[y]);
					for ( z = 0; z < 10; z++ )
					{
							printf("%8d ", vehicles[z]);
						
			}
		printf( "\n" );
		} 
  }
		

	for (x=0; x<10; ++x)
	{
		printf("\n Enter Employee Number : ");
		scanf("%d", &empnum[x]);
	}
	for (y=0; y<10; ++y)
	{
		printf("\n Enter Days : ");
		scanf("%d", &empnum[y]);
	}
	for (z=0; z<10; ++z)
	{
		printf("\n Enter Number of Vehicles Tested : ");
		scanf("%d", &empnum[z]);
	}
		return 0;
}

It is not final yet, in fact the part I am stuck on is in the very beginning.

Code:

printf("\n Employee #");
		printf(" Days");
		printf(" Vehicles\n");
  for ( x = 0; x < 10;x++ )
	{
	  printf("%8d ", empnum[x]);
		for ( y = 0; y < 10; y++ )
			{
				printf("%8d ", days[y]);
					for ( z = 0; z < 10; z++ )
					{
							printf("%8d ", vehicles[z]);
						
			}
		printf( "\n" );
		} 
  }

When I had the printf statments just all by themselves it was lined up perfectly. Of course however all it returned was a row of 0's and not the data in the array. So I tried putting it together in a double nested for loop setup and the outcome is way messed up.
I have messed around with lots of little tweaks, but I can't get a nice looking output.

I have had it where the first two (employee # and days) output ok for one row, and then it outputs the entire vehicles array, then the next row is ok for the first two etc.

Then i have had it where it is all diagonally slanted.

Now I am not even sure what it is doing.

Code:


 Employee # Days Vehicles
       1        5       30       40       20       30       70       10       15

So I am obviously a C noob because I can't figure out how to output a simple 1 dimensional array correctly.
Can anyone give me some insight into what I might be doing wrong?
Thanks

Are you shootin' fer somethin' like this?

Code:

#include <stdio.h>

int main(void)
{
   int empnum[30]={1, 4, 5, 7, 8, 12, 13, 14, 16, 22};
   int days[30]={5, 8, 4, 5, 10, 5, 4, 10, 4, 4};
   int vehicles[30]={30, 40, 20, 30, 70, 10, 15, 20, 40, 50};
   int i;
   printf("%10s  %4s  %8s\n", "Employee #", "Days", "Vehicles");
   for ( i = 0; i < 10; ++i )
   {
      printf("%10d  %4d  %8d\n", empnum[i], days[i], vehicles[i]);
   }
   return 0;
}

/* my output
Employee #  Days  Vehicles
         1     5        30
         4     8        40
         5     4        20
         7     5        30
         8    10        70
        12     5        10
        13     4        15
        14    10        20
        16     4        40
        22     4        50

Exactly what i am looking for. Thanks.

I think I need to start looking for other resources for coding (like the main part of this site) because I was going off of my book and it did not have anything like that.
Thank you much!

The only way it was shown was through nested loops. That way is much simpler... perhaps when I learn more of the basics (I didn't know that you could have "i" be used for all three like that) I can figure things out better.
