It is preferable to separate implementation and specification in C++ software development. Hence, it would be preferable to place a template class definition in a "header"file and the template implementation of the member functions in an implementation file. The implementation could be compiled separately and linked to the application. Most C++ compilers, however, require the template class definitions and member function implementations to be in the same file with the application for compilation. What a specific C++ language aspect requires such restriction? In other words, why they can't be compiled separately as done for non-template class definition and member implementation files.
Give an alternative of resolving such issue as we discussed in the class. Explain why this would resolve the issue. You must clearly demonstrate that you fully understand the issue and its remediation.
