if I type- int []={8,4,7,23} d[2]=1 will it override the old value?

Answer 1

Yes, it will return an error because you need to give your array a name. I assume you want your array name to be 'd'.

But to answer your question, d[2] is currently 7.

Writing d[2] = 1 will indeed overwrite that 7.

Answer 2

hello peeps

Answer 3
