How do I use fprintf and looping to create a table from a single randomized variable?

Hello, I'm fairly new to MATLAB and have run into a problem on an assignment. For part of my program, I am supposed to use this template:

disp('XX|XXXXX.XX|XXXXXXX.XXXXXXXX|XXX.XXXXXXXXXXXXXXXXe+NN|'); 
for i = 1:5
fprintf( WHAT is the command syntax here? Figure this out! );
end

(note that x is a randomly generated 1 by 5 array, so the exact numbers will vary)

To get exactly this output (with different numbers):

XX|XXXXX.XX|XXXXXXX.XXXXXXXX|XXX.XXXXXXXXXXXXXXXXe+NN|
 1| -140.75|   -140.74954935| -1.4074954934790074e+02| 
 2|  115.60|   -115.59673565|  1.1559673565070500e+02|
 3| -187.73|   -187.73244361| -1.8773244361359698e+02|
 4| -196.11|   -196.11471589| -1.9611471588681820e+02|
 5|  -30.86|    -30.86331752| -3.0863317521149384e+01|
 

As shown in the template, it appears that I am to get this output with a single fprintf command.

The closest I've come to this output is :

 disp('XX|XXXXX.XX|XXXXXXX.XXXXXXXX|XXX.XXXXXXXXXXXXXXXXe+NN|');
 fprintf(' %6.2f| %7.8f| %3.16e|\n',[x;x;x])

but this doesn't use the for loop and lacks the first column 1:5.

If x is already a 1 by 5 array, how can I also use a for loop and still only get 5 unique numbers as an output?

I'm completely stumped with this, so any help is greatly appreciated!

Seems like homework to me.

Have you read fprintf help?

Yes, and I think I understand the basic syntax and how to write simpler fprintf commands, but am still running into issues getting fprintf to give the desired output while usung a loop given that x is an array rather than a single value

Well, you made a reasonable start with this homework. I left small part for you to do:

x = [-1.4074954934790074e+02,+1.1559673565070500e+02,-1.8773244361359698e+02,-1.9611471588681820e+02,3.0863317521149384e+01];
disp('XX|XXXXX.XX|XXXXXXX.XXXXXXXX|XXX.XXXXXXXXXXXXXXXXe+NN|');

XX|XXXXX.XX|XXXXXXX.XXXXXXXX|XXX.XXXXXXXXXXXXXXXXe+NN|

for k = 1:numel(x)
    fprintf('%2d|%8.2f|%16.8f|%24.16e|\n',k,..);
end %                                       ^^ hint: use indexing here!

 1| -140.75|   -140.74954935| -1.4074954934790074e+02|
 2|  115.60|    115.59673565|  1.1559673565070500e+02|
 3| -187.73|   -187.73244361| -1.8773244361359698e+02|
 4| -196.11|   -196.11471589| -1.9611471588681820e+02|
 5|   30.86|     30.86331752|  3.0863317521149384e+01|
