从包含 class 指针的 Vector 访问对象

Question

As declared above, I wish to access an object from the vector which contains an abstract class. I'm fairly new.

Account* c = new Current;
vtrAcc.push_back(c("test", 0));

Where "test" is a name and 0 is account ID.

Writing this, throws an error:

expression preceding parentheses of apparent call must have (pointer-to-) function C/C++(109)

We're required to create multiple instances of accounts, thus I use vectors, however, I fail to understand (pointers are hard) how to add parameters to initialize my constructor? Does Account* c = new Current; call its' default constructor?

I expect this to work for now just to understand the thought behind it. Looking throughout StackOverflow I did find this TOPIC from 10 years ago, I understand it. But how do I adapt that with pointers?

Answer 1

try

Account* c = new Current("test", 0);
vtrAcc.push_back(c);

if your vtrAcc is a pointer to account type vector<Account*>vtrAcc;
