Functional C++
Presented at ACCU Oxford (14th September 2015)
Functional C++? As opposed to what — dysfunctional? Well, kind of, yeah. Sure, in C++ the principal unit of composition is called a function, but that doesn't mean it's a functional language. And the idea of restricting mutability of state gets a nod with const, but it's a nod not a hug. And the STL shows influences of functional programming, although it falls short of being compositional. And, yes, sure, C++11 has lambdas, but then again, these days, who doesn't? Lambda calculus was invented in the 1930s.
This talk looks at how to express functional programming ideas in (post)modern C++ in a way that can be considered idiomatic to C++, rather than trying to use the power of overloading and meta-programming to pretend C++ is Haskell or Lisp. In short, immutability beyond const and into shared and persistent data structures, concurrency beyond threading and locks, and thinking about functions as transformations and units of composition rather than actions.

Modify the Date class that was covered in the lecture which overload.pdf
Modify the Date class that was covered in the lecture which overloaded the increment and stream
insertion operators.
The new version of the class should have the following overloaded operators:
(=) subtraction assignment operator :: subtracts the right operand from the left operand and
assigns the result to the left operand.
This operator should cause appropriate number of decrements to the object's 'day' member. It
also checks appropriate decrements to the 'month' and 'year' data members, if necessary.
(>>) cin 's stream extraction operator :: This operator should prompt the user for a date to be
stored in a Date object (you can specify your own format and prompt the user for the same).
Write a driver program and test the operators with the Date objects.
The program should have the following additional requirements:
The operator overloaded functions should be non-member functions.
Input validation (day, month) for the Date object.
The subtraction assignment operator (=) should work with end of month, end of year, and leap
year conditions as shown in the example output below.
Minimum three files (main.cpp, Date.h, Date.cpp). Submit your code as:
LastName_FirstName_Q2.zip (containing all files).
Example output:
Enter a date in format mm-dd-yyyy
01-01-2023
Date d1 is: January 1, 2023 // Check a valid date
Date (d1 -= 3) is: December 29, 2022 // Decrement by 3 days

Python and PostgreSQL: Let's Work Together! | PyConFr 2018 | Dimitri Fontaine
Python is often used to maintain application backends. When the backend should implement user oriented workflows, it may rely on a RDBMS component to take care of the system's integrity.
PostgreSQL is the world's most advanced open source relational database, and is very good at taking care of your system's integrity. PostgreSQL also comes with a ton of data processing power, and in many cases a simple enough SQL statement may replace hundreds of lines of code written in Python.
In this talk, we learn advanced SQL techniques and how to reason about which part of the backend code should be done in the database, and which parf of the backend code is so easier to write as a SQL query.
C Programming :- An Example
We have selected to write a program to create a shop billing program which will allow user to input item details such as name, price, quantity, vat etc . And allow further entry of details by user to calculate the total cost. The Last Output will be shown as a bill. You Can see your previous purchases etc.
Need to make a Java program which calculates the number of days betw.pdf
Need to make a Java program which calculates the number of days between two dates. I am NOT
able to use anything too advanced yet such as import.java.util.Calender, import.java.util.Date; or
import.java.util.GregorianCalender; Here are a couple of examples of what is should look like
when complete. I am having troubles getting my calculations to come out correctly. I’ve also
written the code I have so far.
EXAMPLE
“Enter first date now:
Enter Month: 1
Enter Day: 1
Enter Year: 1900
Enter the second date:
Enter Month: 1
Enter Day: 1
Enter Year: 2400
The first date is: 1/1/1900
The other date is: 1/1/2400
The total number of days between the dates is 182621”
AND
“Enter first date now:
Enter Month: 2
Enter Day: 23
Enter Year: 2016
Enter the second date:
Enter Month: 11
Enter Day: 30
Enter Year: 1955
The first date is: 2/23/2016
The other date is: 11/30/1955
The total number of days between the dates is 22000”

A scrupulous code review - 15 bugs in C++ code
A close look at 15 problems one can find when reviewing C++ code.
Offers code examples.
Covers indexed loops, tainted data, copy and paste errors, problems with comparisons, exceptions, etc.
You can use static code analysis tools to make code review easier. Code analyzers find errors and potential vulnerabilities in code, while saving the developers' time and the companies' money.
Manual code review is expensive - a group of programmers get together regularly to review the code.
One can run static analysis tools regularly to find mistakes and vulnerabilities early.

Modify the Date class that was covered in the lecture which overload.pdf
Modify the Date class that was covered in the lecture which overloaded the increment and stream
insertion operators.
The new version of the class should have the following overloaded operators:
(=) subtraction assignment operator :: subtracts the right operand from the left operand and
assigns the result to the left operand.
This operator should cause appropriate number of decrements to the object's 'day' member. It
also checks appropriate decrements to the 'month' and 'year' data members, if necessary.
(>>) cin 's stream extraction operator :: This operator should prompt the user for a date to be
stored in a Date object (you can specify your own format and prompt the user for the same).
Write a driver program and test the operators with the Date objects.
The program should have the following additional requirements:
The operator overloaded functions should be non-member functions.
Input validation (day, month) for the Date object.
The subtraction assignment operator (=) should work with end of month, end of year, and leap
year conditions as shown in the example output below.
Minimum three files (main.cpp, Date.h, Date.cpp). Submit your code as:
LastName_FirstName_Q2.zip (containing all files).
Example output:

Python and PostgreSQL: Let's Work Together! | PyConFr 2018 | Dimitri Fontaine
Python is often used to maintain application backends. When the backend should implement user oriented workflows, it may rely on a RDBMS component to take care of the system's integrity.
PostgreSQL is the world's most advanced open source relational database, and is very good at taking care of your system's integrity. PostgreSQL also comes with a ton of data processing power, and in many cases a simple enough SQL statement may replace hundreds of lines of code written in Python.
In this talk, we learn advanced SQL techniques and how to reason about which part of the backend code should be done in the database, and which parf of the backend code is so easier to write as a SQL query.
C Programming :- An Example
We have selected to write a program to create a shop billing program which will allow user to input item details such as name, price, quantity, vat etc . And allow further entry of details by user to calculate the total cost. The Last Output will be shown as a bill. You Can see your previous purchases etc.
Need to make a Java program which calculates the number of days betw.pdf
Need to make a Java program which calculates the number of days between two dates. I am NOT
able to use anything too advanced yet such as import.java.util.Calender, import.java.util.Date; or
import.java.util.GregorianCalender; Here are a couple of examples of what is should look like
when complete. I am having troubles getting my calculations to come out correctly. I’ve also
written the code I have so far.
EXAMPLE
“Enter first date now:
Enter Month: 1
Enter Day: 1
Enter Year: 1900
Enter the second date:
Enter Month: 1
Enter Day: 1
Enter Year: 2400
The first date is: 1/1/1900
The other date is: 1/1/2400
The total number of days between the dates is 182621”
AND
“Enter first date now:
Enter Month: 2
Enter Day: 23
Enter Year: 2016
Enter the second date:
Enter Month: 11
Enter Day: 30
Enter Year: 1955
The first date is: 2/23/2016
The other date is: 11/30/1955
The total number of days between the dates is 22000”

The answer would be 5 because Dehydration in a .pdf
The answer would be 5 because: Dehydration in a secondary alcohol usually reacts
via E1 reactions. In E1 reactions, rearrangements occur if possible so although the product
assumed would be 1, a methyl shift occurs. One of the methyl groups from the tertiary carbon
shifts when the molecule is a carbocation, so that the carbocation becomes not a secondary but a
tertiary carbocation. Pictures would make it easier to visualize, but if you look up E1 reactions,
you will understand how rearrangements work.

A. He has a smaller radius than H because He has .pdf
A. He has a smaller radius than H because He has a larger effective nuclear charge
Hydrogen has one proton, helium has two. Hydrogen has one electron, helium has two, but IN
THE SAME ENERGY LEVEL (their average distance from the nucleus is the same). Since the
helium nucleus has increased positive charge, the helium electrons are drawn in toward the
nucleus (due to electrostatic attraction) than the single electron of hydrogen is to its nucleus.
(This is a side effect of imperfect electron shielding).

A transducer is a device, usually electrical, ele.pdf
A transducer is a device, usually electrical, electronic, electro-mechanical,
electromagnetic, photonic, or photovoltaic that converts one type of energy to another for various
purposes including measurement or information transfer (for example, pressure sensors). In a
broader sense (for example in the Viable System Model) a transducer is sometimes defined as
any device that converts a signal from one form to another. A very common device is an audio
speaker, which converts electrical voltage variations representing music or speech, to mechanical
cone vibration. The speaker cone in turn vibrates air molecules creating acoustical energy

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
