Answer 3

I have updated my code for you @Abubakr. Now you can find the terms of any array and can reverse it.

Answer 4

What if I don't know the number of elements in the array? I heard vectors can help me but I don't know how to use them as I still didn't reach them in the course.

Answer 5

thanks @Akash!! but I didn't understand the (sizeof(myArr)/sizeof(myArr[0]))-1 part.
Shouldn't x=sizeof (myArr) be enough?
