c# - Does base class gets instantiated for every new instance? -

-

i have been thinking how clr creates new instances. consider code:

public class base {     public base()     { } }  public class derived : base {     public derived()         : base()     { } }

these questions:

  1. does system.object instance created every time line of code, var baseobj = new base();? how many instances there in memory? 2 or 1?

  2. for line of code: var derobj = new derived();. how many instances created? 3 or 2?

in both samples, there 1 object. there 1 piece of memory allocated , base class 'merges' parents. there 1 class containing methods, fields , properties derived base classes, including base-class-of-all. object.

what think happen if var derivedobj = new derived(); creates 2 instances? how refer 1 not assigned baseobj? there no use in keeping 2 instances of classes alive. 1 do.

i using enumerator values flags: typedef enum { = 0x00, b = 0x01u, // u has no influence, expected c = 0x02u, // u has no influence, expected ... } enum_name; volatile unsigned char* reg = someaddress; *reg |= b; according misra-c:2004 bitwise operations shall not done signed type. unfortunately, compiler iar use signed int (or short or char) underlying type of enums, , option can find relates size, not signedness ("--enum-is-int"). according iar c/c++ development guide arm , pages 169 , 211, can define type of enum s if enable iar language extensions ( -e command-line option, or project > options > c/c++ compiler > language > allow iar extensions in ide). in particular, should define "sentinel" value, make sure compiler chooses correct type. prefers signed types, , uses smallest possible integer type, sentinel should largest positive integer corresponding unsigned integer type can describe. example, typedef enum
