C++ - Basic Error with Arrays of Base Classes
I am a bit stuck right now. I have a base class called B开发者_如何学运维aseBond. ZeroCouponBond and CouponBond inherit from that class. I am looking to create an array that contains both types of bonds. Here is my code:
...
BaseBond port[12];
for (int i=0; i < recordCount; i++)
{
if (bonds[i].CouponRate == 0.0)
port[i] = new ZeroCouponBond(bonds[i]);
else
port[i] = new CouponBond(bonds[i]);
}
Here is the error I am getting: error: no match for ‘operator=’ in ‘port[i]
I know this is probably a simple fix and has to do with when I can declare objects in an array, but I'm relatively new to C++ and don't know all the rules.
Thanks in advance for the help!
You need to do this using pointers:
Change the declaration to this:
BaseBond *port[12];
In your original code, you were trying to assign a pointer to BaseBond
. So it won't compile.
Furthermore, when you use inheritance like this, you have to do it using pointers anyway to prevent object slicing.
