Lab 12 Prelab Questions
1. You have used templates already in 202! Find code from any project
1-4 and paste a few lines below.

2.  What does templated code do when it runs through the compiler?

3. What type of logic is good for templates?

4. Think of a function that would benefit by using templates. Write it.

5. Suppose I have a class called "Holder" which is a templated class,
and lets say I am compiling it with my other file main.cpp like this:
g++ -ansi -Wall main.cpp Holder.cpp , but it is not compiling, just
from the information given above, why would it not compile?

6. A technique when writing templated classes to prevent the compiler
from yelling and screaming at you is to ___________ to both the .cpp
and the .h file.


7. Suppose my main.cpp is:
#include "Holder.h"
#include <iostream>
#using namespace std;
int main()
{
  Holder<string> strHolder("I love c++");
  Holder<int> intHolder(7);
  cout << strHolder << endl;
  cout << intHolder << endl;
  return 0;
}

Write the Holder.h and Holder.cpp so that the program outputs:
Holder has "I love c++"
Holder has "7"

8. What do you think? Can templates save time? Or would you choose a
different way?
