Error Initializing Object Array in C++ -

when run code attempts initialize array of objects, , 1 has invalid value, doesn't seem call constructor, set proper default value. code below produces output:

1 2 1528112104 

toy code:

#include <iostream> using namespace std;  class beeboop {     public:         static const int min_x = 1;         static const int max_x = 2;         beeboop(int x);         int getx() { return x; }         bool setx(int x);      private:         int x; };  int main() {     beeboop boops[] =     {         beeboop(1),         beeboop(2),         beeboop(3)     };      (int = 0; < 3; i++)         cout << boops[i].getx() << endl; }  beeboop::beeboop (int x) {     if(!setx(x))         x = min_x; }  bool beeboop::setx(int x) {     if (x < min_x || x > max_x)         return false;     this->x = x;     return true; } 

why isn't calling constructor , setting default beeboop(3)?

even weirder, if switch order of initialization list to

... beeboop boops[] = {     beeboop(1),     beeboop(3),     beeboop(2) ) ... 

the output becomes:

1 0 2 

so initializes 0, not default.

you're using name x both function parameter , member variable (probably not idea!). therefore need change:

beeboop::beeboop (int x) {     if(!setx(x))         x = min_x; } 

to:

beeboop::beeboop (int x) {     if(!setx(x))         this->x = min_x; } 

otherwise you're modifying parameter x rather setting member variable. (alternatively use unique names parameters , member variables avoid such ambiguities.)

note if had compiled suitable warnings enabled (-wshadow) compiler have been able point out mistakes:

main.cpp: in constructor 'beeboop::beeboop(int)': main.cpp:30:24: warning: declaration of 'x' shadows member of 'beeboop' [-wshadow]  beeboop::beeboop (int x)                         ^ main.cpp:14:13: note: shadowed declaration here          int x;              ^ main.cpp: in member function 'bool beeboop::setx(int)': main.cpp:36:25: warning: declaration of 'x' shadows member of 'beeboop' [-wshadow]  bool beeboop::setx(int x)                          ^ main.cpp:14:13: note: shadowed declaration here          int x;
