new- delete at the right place???

[enemy]

Hello!
Is that array deleted on the right way?

Should not a be deleted instead of z?
Many thanks!

  
#include<iostream>
using namespace std;


  int* push(int b){
    int top;
    int max;
    max=5;

    int* a=new int[5];

    
      srand(time(0));
      int number;
      for(top=0;top<max;top++){
         number=rand()%10;
         a[top]=number;
      }
return a;
}
      
      
      


  int main(){
  int st=5;
  int * z;
  z=pus(st);

  cout<<"main: "<<pus(st)<<endl;
  cout<<z[0]<<" "<<z[1]<<" "<<z[2]<<" "<<z[3]<<" "<<z[4]<<" "<<endl;
  cout<<&z[0]<<" "<<&z[1]<<" "<<&z[2]<<endl;



delete z;
return 0;
}

When you use new, you use delete. When you use new[], you use delete[]. So, to answer your question, no, it is not deleted the right way in your code.

By the way, you should be using a C++ container class or smart pointers (unless your professor or assignment forbid you).

Hello!
If I wrote just delete[] in front of return 0; would it delete the places of heap where I put a[5] from the function pus?

Many thanks!!!

Yes.

Thanks a lot!
And I was also told different, that made confusion!:tup
