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.

c) The function call is encountered in the C++ program

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.
