My solutions to the exercises at the end of Chapter 4 in Part 1 of C++ Crash Course. In this series of exercises, you will make use of a Copy Constructor, Copy Assignment Operator, Move Constructor, and a Move Assignment Operator. Pay close attention to the differences in the elapsed times of Timer 1 and Timer 2. Pay close attention to the fact that when Timer 2 is destroyed, its name will be Timer 1 because of the Copy Constructor, where you will copy Timer 1's name to Timer 2, as well as the time stamp. You will also notice that there is never an indication that Timer 3 is destroyed, but keep in mind we are moving Timer 4 to Timer 3. Therefore, when Timer 4 is destroyed, that is really Timer 3, but after having Timer 4's name moved into its name field. A little bit confusing if you try to breeze through it, but pay close attention to each line of the program, and you will understand exactly what is happening in this exercise.

My solution to Exercise 3-4 from Part 1, Chapter 3 of C++ Crash Course. This one was fairly straightforward, but it illustrates a very important thing on line 13. When you assign new_value to the reference original_ref , it assigns the value to the int that original_ref is pointing to. The result is that new_value and original both have the same value, 200.

For the last while, I have been busy with ESP32 and Arduino programming, but now I finally have time to ram through this book and the exercises. There are a few repositories on Github where people have offered solutions to some of these exercises, but I find that they are often not complete. Therefore, I am endeavouring to make a more complete listing, or at least fill in some of the holes. Here is a video and a link to the repository for the solutions to Part 1, Chapter 1. The exercises can be found at the end of each chapter. I am back-tracking a bit from where I am in Part 1 Chapter 5, which is where I am currently studying.

This exercise is taken from Chapter 2 of the book,  "Beginning C", 5th edition . This is my solution to the problem. https://github.com/pereiradaniel/beginning_c/blob/master/ch2/exercises/2_1/exercise2_1.c // Exercise 2-1 // Write a program that prompts the user to enter a distance in inches and // then outputs that distance in yards, feet, and inches. // There are 12 inches in a foot and 3 feet in a yard. #include <stdio.h> int main(int argc, char* argv[]) { // Constants for conversion process: const int inches_per_foot = 12; const int feet_per_yard = 3; // Variables for user input and calculations: int input = 0, inches = 0, yards = 0, feet = 0; // Prompt user for input in inches: printf("Enter number of inches for conversion to yards, feet, inches: "); scanf(" %d", &input); inches = input; // Convert inches into yards, feet, inches: feet = inches / inches_per_foot; yards = feet /...
