What is the output of the following code snippet?

class CashRegister $\{$ public: void set$\_$item$\_$count$($int count$)$; void set$\_$cash$\_$balance$($double balance$)$; void view$()$ const; void view$\_$count$()$ const; CashRegister$()$; CashRegister$($int item$\_$count$)$; CashRegister$($double cash$\_$balance$)$; CashRegister$($int item$\_$count, double cash$\_$balance$)$; private: int item$\_$count$1$; double cash$\_$balance$1$; $\}$; CashRegister::CashRegister$()\{$ item$\_$count$1=0$; cash$\_$balance$1=0$; $\}$ CashRegister::CashRegister$($int item$\_$count$)\{$ item$\_$count$1=$ item$\_$count; $\}$ CashRegister::CashRegister$($double cash$\_$balance$)\{$ cash$\_$balance$1=$ cash$\_$balance; $\}$ CashRegister::CashRegister$($int item$\_$count, double cash$\_$balance$)\{$ item$\_$count$1=$ item$\_$count; cash$\_$balance$1=$ cash$\_$balance $*$ item$\_$count; $\}$ void CashRegister::view$()$ const $\{$ cout $<<$ "Balance $="<<$ cash$\_$balance$1$; $\}$ int main$()\{$ CashRegister r$1(3,50)$; r$1.$view$()$; return $0$; $\}$

Balance $=50$

Balance $=0$

Balance $=150$

The answer cannot be determined because some constructors do not initialize all data members.
