In C#, I need to write a data structure for a circular dynamic array class.

This CDA.C class must be created to work with the following header file cda.h

I just need help with the first three defined lines. I believe I have the *newCDA created and this is it below, I need help creating setCDAdisplay and setCDAfree

this is the mothd behavoir and assertions for the following fucntion

#ifndef-CDA-INCLUDED- #define-CDA-INCLUDED- #include typedef struct cda CDA; extern CDA *newCDA (void); extern void setCDAdisplay(CDA *items, void (*display) (void *,FILE *)); extern void setCDAfree(CDA *items, void (*free) (void *)); extern void insertCDA (CDA *items,int index,void *value) extern void *removeCDA (CDA *items,int index); extern void unionCDA(CDA *recipient,CDA *donor); extern void *getCDA (CDA *items,int index); extern void *setCDA(CDA items,int index,void *value); extern int sizeCDA (CDA *items) extern void displayCDA (CDA *,FILE *); extern int debugCDA(CDA *,int level); extern void freeCDA (CDA *); #define #define #define #define insertCDAfront (items , value) insertCDAback(items,value) removeCDAfront(items) removeCDAback(items) insertCDA(items,0, value) insertCDA(1tems, sizeCDA(items),value, removeCDA(items,0) removeCDA( items, sizeCDA( Items )-1) #endif
