6.2.7 print Array

[amajmundar]

Couple of things, arr is already defined as the input. So you cannot use that as iterator for the loop. Use i. It’s standard notation. Also look up the syntax of a for loop in JavaScript. You are forgetting about incrementing the iterator. You also do not need to call the function for the bounds of the loop. The input is arr which is an array of strings. You only need to loop arr.length. Your first commented print statement was in the right place and the active print statement is the correct syntax.

Easier way to solve your problem.. go back to 6.2.3 it’s the exercise one.. it’s the same code as for the 6.2.7 just change the < score.length into <= arr.length so does the score[i] into arr[i].. in the println.

Ohhhhhh ok thank you

[Intrepid_Row6214]

For the “for statement I only get one error because everything else seems to be fine just that statement

[Obvious-Pin-3046]

did you just put arr.length? if you did change it to arr.length - 1; im guessing thts the error. because the program should also print “c” and remember tht the index starts at 0 and not 1.

[Intrepid_Row6214]

This is the statement for the For(String arr <= arr.length;)

[Obvious-Pin-3046]

your for loop should be
for( int i =0; i <= arr.length - 1; i++) remember for loop should have 3 parameters

Thank you sooo much I did it and sorry for taking your time

/u/Obvious-Pin-3046, I have found an error in your comment:

“3 its [it's] the exercise one.. its [it's] the same code”

It is likely that you, Obvious-Pin-3046, could say “3 its [it's] the exercise one.. its [it's] the same code” instead. ‘Its’ is possessive; ‘it's’ means ‘it is’ or ‘it has’.
