Swift - Operators and Expressions

You want to overload the * operator to multiply a Matrix by an Int scalar in Swift. Which of these is the correct way to declare this operator overload inside the Matrix struct?

Astatic func * (lhs: Matrix, rhs: Matrix) -> Matrix { ... }

Bfunc * (lhs: Matrix, rhs: Int) -> Matrix { ... }

Cstatic func * (lhs: Matrix, rhs: Int) -> Matrix { ... }

Dstatic func * (lhs: Int, rhs: Matrix) -> Matrix { ... }

Step-by-Step Solution

Solution:

Step 1: Understand operator overload for scalar multiplication
Multiplying a Matrix by an Int scalar means lhs is Matrix, rhs is Int, returning a Matrix.
Step 2: Check function declaration rules
Inside Matrix struct, operator overload must be static func with parameters (Matrix, Int) and return Matrix.
Final Answer:
static func * (lhs: Matrix, rhs: Int) -> Matrix { ... } -> Option C
Quick Check:
Matrix * Int overload = static func with (Matrix, Int) [OK]

Quick Trick: Match parameter types and use static func inside struct [OK]

Common Mistakes:

Omitting static keyword
Swapping parameter order incorrectly
Using wrong parameter types
