C++ Fundamentals

By: Antonio Mallia, Francesco Zoffoli

Overview of this book

C++ Fundamentals begins by introducing you to the C++ compilation model and syntax. You will then study data types, variable declaration, scope, and control flow statements. With the help of this book, you'll be able to compile fully working C++ code and understand how variables, references, and pointers can be used to manipulate the state of the program. Next, you will explore functions and classes — the features that C++ offers to organize a program — and use them to solve more complex problems. You will also understand common pitfalls and modern best practices, especially the ones that diverge from the C++98 guidelines. As you advance through the chapters, you'll study the advantages of generic programming and write your own templates to make generic algorithms that work with any type. This C++ book will guide you in fully exploiting standard containers and algorithms, understanding how to pick the appropriate one for each problem. By the end of this book, you will not only be able to write efficient code but also be equipped to improve the readability, performance, and maintainability of your programs.

Lesson 1: Getting Started

Activity 1: Find the Factors of 7 between 1 and 100 Using a while Loop

  1. Import all the required header files before the main function:

    #include <iostream>
  2. Inside the main function, create a variable i of type unsigned, and initialize its value as 1:

    unsigned i = 1;
  3. Now, use the while loop adding the logic where the value of i should be less than 100:

    while ( i < 100){ }
  4. In the scope of the while loop, use the if statement with the following logic:

    if (i%7 == 0) {
       std::cout << i << std::endl;
  5. Increase the value of the i variable to iterate through the while loop to validate the condition:


    The output of the program is as follows:


Activity 2: Define a Bi-Dimensional Array and Initialize Its Elements

  1. After creating a C++ file, include the following header file at the start of the program:

    #include <iostream>
  2. Now, in the main function, create a bi-directional array named foo of type integer, with three rows and three columns, as...
