Swift - Variables and Constants

What will be printed by the following Swift code?

typealias Vector = (dx: Int, dy: Int)
let movement: Vector = (dx: 4, dy: 6)
print(movement.dx * movement.dy)

A(4, 6)

B24

C10

DError: Cannot multiply tuple elements

Step-by-Step Solution

Solution:

Step 1: Understand the typealias
Vector is a tuple with two Int components: dx and dy.
Step 2: Evaluate the expression
The code multiplies movement.dx (4) by movement.dy (6), resulting in 24.
Final Answer:
24 -> Option B
Quick Check:
Verify tuple element access and multiplication. [OK]

Quick Trick: Multiply tuple elements accessed by name correctly. [OK]
