Dear Kees and WJ,
I'm sorry to disturb, but I would rather do it this way:
a = newArray(0,1,2,3,4);
for (i=0; i<a.length; i++)
        a[i]*=5;
Array.print(a);
My best regards,
Philippe

Dear WJ,

Try

a = newArray(0,1,2,3,4);
b = newArray(5);
for (i=0; i<a.length; i++)
        b[i] = a[i]*5;
Array.print(b);

Best wishes

Kees

Subject: Apply multiplication to all elements in an array

Hi there,

I'm new to coding and can someone guide or direct me to how I can multiply a
constant (say 5) to an array of elements:

For e.g. a = newArray(0,1,2,3,4);

I wish to get another array whereby: b = 0, 5, 10, 15, 20

Thanks.
WJ
