How do you use this repository - Devlopment environment setup

Within the .devcontainer folder, you'll find a file that describes a C++ development environment. By utilizing this file in Visual Studio Code, you can establish a connection to a Linux-based development environment. The steps involved are as follows:

Make sure you have Docker Desktop installed and running on your computer
Install the Remote Development extension pack in Visual Studio Code Once the installations are complete, follow these steps:
Open the Command Palette (usually by pressing Ctrl+Shift+P) and search for Dev Containers: Clone Repository in Container Volume
You may need to authorize the extension for GitHub authentication. You will be redirected to your web browser to complete this process
A development container will be created and started in the background. You may see a terminal window open while the container is being created

Assignments

1. Primitive types & variables

Task 1.1: ./primitive_types/primitive_types.cpp: fundamental types

In the code, you will find variable declarations that need to be completed with initialized declarations. Please select the appropriate value from the commented line above for each variable.

2. Operators

Task 2.1: ./operators/cast_operators.cpp: static_cast operator

Write the toChar function return value so that it converts the asciiValue variable, which is passed as a parameter, to a char type using static_cast operator

Task 2.2: ./operators/cast_operators.cpp: dynamic_cast operator

The if statement condition shall be true if the currently iterated animal instance is of type Dog

Task 2.3: ./operators/cast_operators.cpp: dynamic_cast operator

The if statement condition shall be true if the currently iterated animal instance is of type Cat

Task 2.4: ./operators/reinterpeter_cast.cpp: reinterpeter_cast

Convert the SignedInt structure to an UnsignedInt type using bitwise copying. Can you determine what the value of the unsignedInt->value member will be?

Task 2.5: ./operators/try_catch.cpp: scope resolution

Observe where and how the result variable is declared. Initialize it to 0.0 in the main function

Task 2.6: ./operators/try_catch.cpp: exception handling

Extend the divide function so that it throws an exception when attempting to divide by zero

Task 2.7: ./operators/try_catch.cpp: exception handling

Implement a try-catch block that calls the divide function and can catch any exceptions thrown by it

3. Conditions

Task 3.1 ./conditional/if_statement.cpp: if statement condition

Create a boolean variable that can be used as a condition in the if statement below to determine if a number is even or odd

Task 3.2 ./conditional/if_statement.cpp: if statement condition

Create an instance of the class above so that it can be used as a condition in the if statement below to determine if a number is even or odd. This demonstrates that the condition part of an if statement can be an object of a class that can be unambiguously converted to a boolean

Task 3.3 ./conditional/if_statement.cpp: fallthrough

Complete the implementation of the selectMenu function using a switch statement to print out the selected meals. Implement only one meal type per case. Tip: you can use the fallthrough effect here.

Task 3.4 ./conditional/if_statement.cpp switch selestatement condition

Implement a switch statement that can print the day of the week corresponding to a given number (e.g., 1 - Monday, ...). The day number should be the value returned by the getRandomNumber function. Tip: you can declare and initialize variable within the selection statement itself.

Task 3.5 ./conditional/constexpr.cpp

Implement a conditional statement that can determine whether a constant variable holds a positive or negative number

4. Loops

Task 4.1 ./loops/loops.cpp

In the main function, you will find an array containing numbers. Print the numbers in the array to the console using the following loop types:

traditional for loop
do-while loop
while loop
range-based for loop

Task 4.2 ./loops/cond-expr.cpp

In the main function, create an instance of the above class to drive a single iteration of the following while loop. The example aims to demonstrate that a loop's condition can be an instance of a class that can be unambiguously converted to a boolean type.

Task 4.3 EXTRA ./loops/user_defined_collection.cpp

The SimpleArray class implements a custom container with a fixed size, storing integer values. Implement a range-based for loop to print the elements of the created instance (myArray). The example illustrates that range-based for loops work with custom containers that define begin() and end() methods.

5. Functions

Task 5.1 ./functions/deafult_arguments.cpp: default arguments

Implement the printMessage function that takes a string variable as a parameter containing the message to be printed and an integer times indicating how many times the message should be printed. If no argument is provided for times when calling the function, it should print the message once.

Task 5.2 ./functions/multiple_value_return.cpp: return with struct

Implement the calculatePoint function that returns a Point structure with a new point that is shifted 1 unit in the positive direction relative to the input x and y values

Task 5.3 ./functions/multiple_value_return.cpp: return with tuple

Implement the calculatePointAndDistance function that returns a tuple containing two points derived from the input parameters, with coordinates (x1, y1) and (x2, y2), as well as the distance between the two points.

Task 5.4 ./functions/pass_by.cpp: pass by reference

Implerment the swap function that exchanges the values of two variables. The modification should be visible to the caller.

Task 5.5 ./functions/pass_by.cpp: pass by reference

Implement the getLength function that returns the length of the input string.

Task 5.6 ./functions/auto.cpp: auto keyword

Implement the max function that returns the greater of the input parameters a and b. The return type of the function should be deduced from the return expression.

Task 5.7 ./functions/inline.cpp: inline keyword

Implement the isVowel inline function that determines whether the input character is a vowel

Task 5.8 ./functions/constexpr.cpp: constexpr keyword

Implement the factorial function that calculates the factorial of the input variable number. The function can be called with a compile-time constant expression, and call it in the main function with value 5

Task 5.9 ./functions/noexcept.cpp: noexcpet keyword

Implement the sumElements function that sums the elements of the input vector. This function should not throw any exceptions

Task 5.10 ./functions/atexit.cpp: atexit keyword

The cleanup function checks whether the numbers pointer points to an allocated memory area and, if so, frees the allocated space. Register this function to run before the program terminates normally.
