Chapter 19 // Drill 1, 2, 3, 4, 5, 6, 7, 8 ,9, 10, 11, 12, 13 - Principles & Practice Using C++

In these exercises I am using Visual Studio 2017 and the std_lib_facilities header provided by Stroustrup.

Chapter 19 // Drill 1

Define template<typename T> struct S { T val; };.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%201

.

Chapter 19 // Drill 2

Add a constructor, so that you can initialise with a T.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%202

.

Chapter 19 // Drill 3

Define variables of types S<int>, S<char>, S<double>, S<string>, and S<vector<int>>; initialise them with values of your choice.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%203

.

Chapter 19 // Drill 4

Read those values and print them.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%204

 I assume he meant read them in using cin?

Chapter 19 // Drill 5

Add a function template get() that returns a reference to val.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%205

.

Chapter 19 // Drill 6

Put the definition of get() outside the class.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%206

.

Chapter 19 // Drill 7

Make val private. 

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%207

.

Chapter 19 // Drill 8

Do 4 again using get().

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%207

I guess he didn't mean to use cin earlier...literally just print them? Why use read? See code for drill 7 as this does the same thing.

Chapter 19 // Drill 9

Add a set() function template so that you can change val.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%209

.

Chapter 19 // Drill 10

Replace set() with an S<T>::operator=(const T&). Hint: Much simpler than Section 19.2.5.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%2010

.

Chapter 19 // Drill 11

Provide const and non-const versions of get().

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%2011

.

Chapter 19 // Drill 12

Define a function template<typename T> read_val(T& v) that reads from cin into v.

Github: https://github.com/l-paz91/principles-practice/blob/master/Chapter%2019/Drills/Drill%2012

Ok, so he definitely didn't mean to read in values in drill 4. I provided the operator overload version in 4 but I implemented the function here as well.

Chapter 19 // Drill 13

Use read_val() to read into each of the variables from 3 except the S<vector<int>> variable.

Github: .

See drill 12 as I did that there...I also already read into the vector...
