my @array=('data1','data2'); my @array1=('data1','data2');
my ($i,$k);
$i=7;
$k=7;
while($i){
$array [++$#array] = 'ree';
$i--; print "@array";
}
while($k){
push(@array1,'ree');
$k--;
print "@array1";
}
Are these two while loop are doing the same functionality ?
What may be the difference?
Answer / guest
The above two while loops are used to add the elements into
the end of the array.
But in first while loop we are manually getting the index of
the last element in the array then we are storing the
element into next index.
But push internally performing that operation.
And the push() has some advantages also.
Using push we can add multiple items into an array in a
single instance.
But this is not possible in the fist while loop.
