dynamic array of a nested class with an array in it? Can it be done? -

this code compiles crashes instantly. i've tried on devcppportable. trying make class can store lot of complex data (i.e. object has multiple property sets , each set carries multiple figures).

each object created have unique number of property sets , internal property values. able shape class upon declaration not allocate bunch of unused space. possible?

#include<iostream> using namespace std;  class {     public:         int amount;         struct b         {             int max;             int* prop;             b() {}             void set(int&);             ~b(){delete prop;}         };         b* property;         a(int amt, int max0, int max1=0, int max2=0);         ~a(){delete property;} };  int main() {     object(2, 3, 5);     return 0; }  a::a(int amt, int max0, int max1, int max2) {     amount = amt;     property = new b[amt];      switch(amt)     {         case 3:             property[2].set(max2);         case 2:             property[1].set(max1);         case 1:             property[0].set(max0);     } }  void a::b::set(int& m) {max = m; prop = new int[max];} 

you allocate property new[] deleting delete, not delete[]
