hello in this assignment statement int arr[ ] = new int[3]; is the "[3]" effectively all zeros? |
| 00:04 |
|
Jantz |
in the array? |

aditsu |
the array is filled with zeros; "[3]" is just the syntax specifying the size of the array |
| 00:07 |
|
Jantz |
so could it have been int arr[]=0? |
| 00:07 |
|
aditsu |
no, 0 is an int, not an array |
| 00:07 |
|
Jantz |
sorry intarr[3]=0 |
| 00:07 |
|
Jantz |
ok |
| 00:07 |
|
aditsu |
there you are setting an element of the array, not the array itself |
| 00:08 |
|
aditsu |
(assuming you have an array named "intarr") |
| 00:08 |
|
Jantz |
so things are alot different for array protocols on different sides of the assignment operator yeah? |
| 00:08 |
|
Jantz |
ok |
| 00:09 |
|
Jantz |
or not? |
| 00:09 |
|
aditsu |
well... you have 3 different things here: array declaration, array creation, and array access |
| 00:10 |
|
Jantz |
so creation is [ |
| 00:10 |
|
Jantz |
sorry [] |
| 00:10 |
|
aditsu |
they all involve square brackets |
| 00:11 |
|
aditsu |
declaration is "int arr[]" or "int[] arr", creation is "new int[n]" and access is "arr[i]" |
| 00:11 |
|
Jantz |
thanks |
| 00:12 |
|
aditsu |
there would be one more situation - initialization, e.g. you can write "int arr[] = {1,2,3}" |
| 00:12 |
|
aditsu |
initialization would be at the point of declaration; all the other things can be separate |
| 00:14 |
|
Jantz |
so is arr[i] = i creation and declaration all in operating from the for loop? |
| 00:14 |
|
aditsu |
neither, that is just access |
| 00:15 |
|
Jantz |
is there any encapsulation or polymorphism going on here? |
| 00:15 |
|
Jantz |
ok just access right gotcha |
| 00:15 |
|
aditsu |
nope |
| 00:15 |
|
Jantz |
ok |
| 00:16 |
|

Jantz |
or both |
| 00:20 |
|
Jantz |

aditsu |
I have no idea :p |

|
Jantz |
