Accelerated C++ Solution to Exercise 5-0

Exercise 5-0

Compile, execute, and test the programs in this chapter.


Chapter 5 contains 3 core sets of applications. I believe it makes sense to split Exercise 5-0 into 3 separate parts (i.e. 3 separate posts) for greater relevance and readability. Click the hyperlinks below to drill down.

Part 1 / 3

Click here to see full Solution to Exercise 5-0 (Part 1 / 3) : We extend the Solution to Exercise 4-0 (i.e. the student grading program) to include a capability that split the set of students (objects) into two groups – namely the passing students and failing students. This capability is enabled by a new “home-made” function called extract_fails. This function can be written in 4 different versions in which all 4 versions deliver the same result, with the slight difference in terms of efficiency. It goes from version 1 being the most primitive / inefficient, to version 4 being the most elegant / efficient. We will describe and test out each version one-by-one.

Part 2 / 3

Click here to see full Solution to Exercise 5-0 (Part 2 / 3): This is a very simple program with the purpose of splitting a line of text (i.e. a input string) into words (i.e. an output vector<string>).

Part 3 / 3

Click here to see full Solution to Exercise 5-0 (Part 3 / 3): This is a fairly clever yet simple-to-understand program. This exercise demonstrates 4 things: (1) how to create a paragraph and store in the form of a vector<string> container, (2) how to display the paragraph with and without a frame, (3) how to concatenate two paragraph “pictures” vertically, (4) how to concatenate two paragraph “pictures” horizontally.


If in doubt, try reading through chapter 5 multiple times to help understanding how the “bits and pieces” work individually and as a whole. It’s all in the book. What the book does not contain however, is the actual implementation of programs through an IDE (like Code::Block) and demonstrate what the the output results may look like. This post (and all the other posts in this Accelerated C++ series) aims to fill in that gap.
