The code for a template function is generated when:

a. The function template declaration (prototype) appears in the C++ program.
b. The function template is encountered in the C++ program.
c. The function call is encountered in the C++ program
d. At runtime, when the function call is executed.

Part c)
Explanation: Code for template function is generated by the compiler when the call is encountered during the compiling of the C++ program.
Note to the Instructor: The answer to this question is very compiler dependent. It is based in part on the PITFALL: Compiler Complications in the text on page 659 . Use of this question requires investigation of problems with your compiler’s template facility.
