What is the problem with info_all()?

By the way: line 100 is wrong. You must not call delete where you didn't previously called new for.

Actually to remove the person you need a loop on line 98 which goes from the determined index to num_of_people - 1. Thus you may initialize index (line 89) with num_of_people.

I don't get the total amount of people i just get the info of "p1". In line 100 I'm trying to delete the array by using a pointer.

[coder777]

Well, you add

p1 -> r1
p2 -> r2

then you print r1. So just remove r2 and use r1 instead.

In line 100 I'm trying to delete the array by using a pointer.

Yes, that's wrong.

[spax1111111]

and how would you do it?

[coder777]

int main()
{


   Person p1("NN","XX",123,212.21);
   Person p2("NN2","XX2",1212,2121.212);
   
   p1.info();
   
   Register r1;
r1.add(p1);
r1.add(p2);
   Register r2;r2.add(p2);
   r1.info_all();

  return 0;
}

i understood that what i meant was how would you delete the person from the array :D

[coder777]

  void delete_prs(Person p1){
    int index=-1;
    Person *tmp=NULL;
    for(int i=0;i<num_of_people;i++){
      if(p1.getName()==prs_arr[i].getName() && p1.getLast()==prs_arr[i].getLast()){
        index=i;
        break;
      }
    }
    
    if(index>=0){
       --num_of_people;
    for(int i=index;i<num_of_people;i++)
{
       prs_arr[i]=prs_arr[i+1];
}
    }

  }
