Please help me to do my homework!!!

class creature_society {
     public:
        int N;
        creature* plasma;
        int M,L,good_thrsh,bad_thrsh;
     public:
        creature_society(int,int,int,int,int);
        ~creature_society();
        int beat_cr(int);
        int bless_cr(int);
        int clone_next(int);
        int clone_zobies(int);
        int no_of_good();
        int no_of_zobies();    
            
};

And this is the constructor

creature_society::creature_society(int a,int b,int c,int d,int e) {
int k,epilogi,f;
long curtime;

N=a;
M=b;
L=c;
good_thrsh=d;
bad_thrsh=e;
curtime=time(NULL);
srand((unsigned int) curtime);
creature *plasma = new creature[N];
for(k=0;k<=N-1;k++) {
epilogi=(rand()%2)+1;
if (epilogi==1) {
    f=rand()%42;
    plasma[k] = good_creature(L,k,good_names[f]); 
    }
else {
    f=rand()%54;
    plasma[k] = bad_creature(L ,k,bad_names[f]); 
    }
}
cout<<"\nA creature society has been constructed\n"<<endl;
}
