ios - How Memory allocated without calling alloc - NSArray,NSString -

i have 2 viewcontroller:

viewcontroller1 - has property nsarray array1 , in viewdidload assigning self.array1 = @[@"a",@"b",@"c",@"d"];

question 1 : how without coding alloc, array1 allocated memory , storing values?

question 2 : have viewcontroller2 - has property nsarray array2

using prepareforseque method, assigning array1 value array2,

[[segue destinationviewcontroller] setarray2:self.array1];

in viewcontroller2 - viewdidload if log array2 getting value. got array2 memory allocated?

its called syntactic sugar, compiler allocates needed memory. array2 pointer. assign memory address of allocated memory of array1
