I tried to write a findlargest function using recursion and varible ii is the size of array, but it did not work.

I guess my problem is "arr[i]=apple[i].v()" but I don't know why it's wrong

int ii-0 class complexType private: float realnumber-0; float imaginarynumber-0; float value-realnumberrealnumber imaginarynumber imaginarynumber; public: complexType(float real-e,float imaginary 8) real-reaInumber imaginary-imaginarynumber void setcomplex float real, float imaginary rea Inumbererealj imaginarynumber=imaginary; float v() const return value
