What are the main properties that can be distinguished in data types passed by value?

Data types that are passed by value have the following main properties:

• Copying on transfer: when passing a value to a function or assigning it, a copy of the original value is created, and changes to the copy do not affect the original.
• Data isolation: changes in the copy are not reflected in the original object, preventing side effects.
• Typically used for small and simple data: for example, numbers, boolean values, structures.
• Performance: passing by value can be faster for small data, as it does not require reference management.

Example in Swift:

struct Point {
    var x: Int
    var y: Int
}

var p1 = Point(x: 10, y: 20)
var p2 = p1 // creates a copy of p1
p2.x = 30
print(p1.x) // 10, original remains unchanged
