Chapter 4 // Exercises 1-10 - The C++ Programming Language

 For this exercise I'm using Visual Studio Community 2022 and the header file std_lib_facilities:

The exercises can be found online and are not actually in the book:

Chapter 4 - A Tour of C++: Containers and Algorithms

Exercise 1

When first reading this chapter, keep a record of information that was new or surprising to you. Later, use that list to focus your further studies.

1. I didn't know that for_each() is classed as an algorithm. The more you know.

Exercise 2

List 5 standard library containers.

1. std::vector

2. std::array

3. std::map

4. std::deque

5. std::list

Exercise 3

List 5 standard library algorithms.

1. for_each()

2. find()

3. search()

4. copy()

5. remove()

Exercise 4

List 5 standard library headers.

1. #include <string>

2. #include <list>

3. #include <iostream>

4. #include <vector>

5. #include <random>

Exercise 5

Write a program that reads a name (a string) and an age (an int) from the standard input stream cin. Then output a message including the name and age to the standard output stream cout.

Exercise 6

Redo exercise 5, storing several (name, age) pairs in a class. Doing the reading and writing using your own >> and << operators.

Exercise 7

Initialise a vector<int> with the elements 5, 9, -1, 200 and 0. Print it. Sort it, and print it again.

Exercise 8

Repeat exercise 7 with a vector<string> initialised with "Kant", "Plato", "Aristotle", "Kierkegaard", and "Hume".

Exercise 9

Open a file for writing (as an ofstream) and write a few hundred integers to it.

Exercise 10

Open the file of integers from exercise 9 for reading (as an ifstream) and read it.
