Question

What are the elements of C?
A = [1, 2, 3, 4]
B = [10, 20, 30, 40]
C = A + B

Answer 1

In the context given, C would be the concatenation of arrays A and B, resulting in C = [1, 2, 3, 4, 10, 20, 30, 40].

Step-by-step explanation:

The student is asking about the result of combining two arrays A and B to form a third array C. In most programming contexts, adding two arrays together will concatenate them, meaning the elements of array B will follow the elements of array A in array C. However, this is not an operation following vector addition or scalar multiplication, which are common in physics and mathematics. It is simply an operation related to data structures in computer programming.

Therefore, if A = [1, 2, 3, 4] and B = [10, 20, 30, 40], then C = A + B would result in C = [1, 2, 3, 4, 10, 20, 30, 40].
