Cannot Call Another Class - ERR - Unresolved External Symbol?

In raw. Cpp you have to define foo like this.

As Mihai was saying, you can also define it in the Header file (.h/. Hpp), but that is considered bad practice if your class method is complex in any way.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
