In C++, it is the order of the class inheritance and of the member variables that determine the initialization order, not the order of an initializer list:
#include < iostream > class CSomeClass {public:CSomeClass(int n){std::cout << "CSomeClass constructor with value ";std::cout << n << std::endl;}} ; class CSomeOtherClass {public:CSomeOtherClass() //In this example, despite the list order,: obj2(2), obj1(1) //obj1 will be initialized before obj2.{//Do nothing.}private:CSomeClass obj1;CSomeClass obj2;} ; int main( void ) {CSomeOtherClass obj;return 0;}
