my @array=('data1','data2'); my @array1=('data1',

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 / sugumar

Both are absolutely same in giving the output.
but in first method "$array [++$#array] = 'ree';"
we are preincrementing the array index manually and assigning the latest index to 'ree'; (SLower since we doing it as manual)

Where as in the second method, push is an array function where we need not care about index. it automatically increases the index value for the array. (Faster)

Both give same output as

data1 data2 ree
data1 data2 ree ree
data1 data2 ree ree ree
data1 data2 ree ree ree ree
data1 data2 ree ree ree ree ree
data1 data2 ree ree ree ree ree ree
data1 data2 ree ree ree ree ree ree ree

VALUES FOR K
data1 data2 ree
data1 data2 ree ree
data1 data2 ree ree ree
data1 data2 ree ree ree ree
data1 data2 ree ree ree ree ree
data1 data2 ree ree ree ree ree ree
data1 data2 ree ree ree ree ree ree ree
