Output of the last line? let a=4 print(a&+0) print(a&-O) print(a&0) print(a<<1) print(a>>1) print(a<<2)

Correct output? struct a1 [ var x = 0.0, y = 0.0 } struct b1 { var w = 0.0. h = 0.0 }

Options the code that will generate compilation error when executed. func abc(inout a: T, inout _ b: T) { let a1 = a a = b b = a1 print('\(a) \(b)') }
