|Structure is of value type, so its value is not changed.|

|Structures are value types and stored on stack not on heaps.|

|As Structures are value type. They hold different memory location for each instance (struct in this case is value type ). Hence x.i would point to one mem location whereas for y.i to another.
Hence fun(x) would call the fun method. But again y.i is assigned 20. Hence a Console would give 20 first and then control would be transferred to main() again and the next statement for x.i ( print ) would give 10.
Hence the output : 20 10.

|Structure is not matter this place. That method was call by value. So, the value not changed in memory structure.|

|Does structures have constructor. I have no idea. Does anyone?|
|Sharan said: (Mar 4, 2015)|
|Structures have default constructor.|

|X and Y are totally different so answer is 20, 10.|

|In general, the changes in the function prototype with parameters do not reflect on arguments of the calling function (because the types of variable here is value type).
If we use ref keyword with parameters and arguments then the changes on the parameter are directly reflected on arguments and they are become reference type and allocate same memory address.

|Structures contain defined constructor.|
