Question

I have a template list in my main which has a template class object in it.

List<serviceInfo<T>> priceList;

In order for me to get it working, I will have to declare template above my main

template <class T>
int main()

which will give me the following error:

LNK2019: unresolved external symbol main referenced in function
__tmainCRTStartup

Answer 1

main should never be templated.

Instead, you should replace T in List<serviceInfo<T>> with an actual type.
If you want to have different types of serviceInfo<T> in your list, create several lists.
