c++ - Where are const objects stored -

i understand functions should not return references automatic variables. wanted understand constant objects stored i.e if stored in memory section along static global variables .

here code on visual studio 8 . looks const objects stored auto variables. assuming things right or implementation specific or depend on whether constructor trivial ?

would great if explain why each of these cases behave way do.

//here i'm intentionally returning ptr local const ptr hope syntax right  const char* const* get_const_char_ptr() {     const char * const ptr = "downontheupside";     return &ptr; }  const int& get_const_int() {             const int magic_number = 20;     return magic_number; }  const string& get_const_string() {            const string str("superunknown");     return str; }  const string* get_const_string_ptr() {     const string str("louderthanlove");     return &str; }  int main() {     //case1     const int &i = get_const_int();     cout<<"case1:"<<i<<endl;      //case 2     const char * const* c =get_const_char_ptr();     cout<<"case2:"<<*c<<endl;      //case3     const string &str = get_const_string();     //this crashes     //cout<<"case3:"<<str<<endl;      return 1; } 

constant objects allocated within function other automatic variable; have const types. global (and class-static) variables different: constants can placed in read-only parts of executable file , copied memory. used things string , integer constants; not believe used nontrivial constructor.
