This document discusses pointers in C programming and provides 5 questions to test understanding of pointers. It then provides explanations for the answers.
The questions cover topics like pointer sizes, pointer arithmetic, strong typing, string literals assigned to integers, address of pointers, and logical operators on pointers. The explanations clarify common misconceptions around pointers.
Pointers are among C’s most powerful, yet most difficult concepts to master. Some tasks like dynamic memory allocation done only by using pointers. So it is essential to learn pointers.
Pointers are a type of variable, just like int, double, etc., except instead of storing a value, they store a memory address of another variable.

إذا كُنت من هواة البرمجة ولم تُحلّق في هذا العالم بعد فالطريق ما زال مفتوحًا أمامك، فالفضاء موجود أمامك لتختار أحد المسارات وتسلكها فورًا.
اختيار المسار بحد ذاته هو الحاجز الذي نقف عنده في الغالب، بل ويستغرق وقتًا أطول من وقت التعلّم والمُمارسة، لكن ليس هُناك أجمل من الاستفادة من التقنيات الموجودة بين أيدينا حاليًا لتطوير أدوات نستطيع الاستفادة منها.

Almost everything can be done using refactoring tools:
* How to get buy-in for refactoring? (use Technical Debt quantification tools)
* How to identify refactoring candidates? (use smell detection tools)
* How to prioritize / identify what to refactor first? (use reports from design analysis tools)
* How do I identify dependencies and evaluate impact of refactoring? (use visulization tools)
* How to I actually perform refactoring? (Use IDE support for automated refactoring and use them!)
Deriving from a rich experience in using tools for refactoring in real-world projects, this talk takes you through a whirl-wind tour of refactoring tools (of course for Java). What's more, this talk includes quick demos of some of these tools so you can see them in action.

HIPC is a premier conference and hence getting a paper accepted in HIPC workshop would be quite an accomplishment for any blockchain/AI enthusiast. Check out the details in this poster on submissions.
I have been fortunate to have worked with some geeks with incredible coding skills. I felt amazed at how they can play games with compilers, perform magic with their incantations on the shell, and solve some insanely complex algorithm problems with ease. I naively assumed that they are going to achieve greatness in near future. Alas, I was wrong. Really wrong. [Read the rest of the article ... ]
Many students reach out to me asking for project ideas they can do as a summer project for learning. Here is an interesting project idea - implement your own java disassembler (and expand it to a VM later).
Design Patterns - Compiler Case Study - Hands-on ExamplesGanesh Samarthyam
This presentation takes a case-study based approach to design patterns. A purposefully simplified example of expression trees is used to explain how different design patterns can be used in practice. Examples are in C#, but is relevant for anyone who is from object oriented background.

Awareness of design smells - Design comes before code. A care at design level can solve lot of problems.
Indicators of common design problems - helps developers or software engineers understand mistakes made while designing and apply design principles for creating high-quality designs. This presentation provides insights gained from performing refactoring in real-world projects to improve refactoring and reduce the time and costs of managing software projects. The talk also presents insightful anecdotes and case studies drawn from the trenches of real-world projects. By attending this talk, you will know pragmatic techniques for refactoring design smells to manage technical debt and to create and maintain high-quality software in practice. All the examples in this talk are in Java.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

1. The Joy of
Programming
Understanding Pointers in C S.G. GaneSh
Pointers are the forte of C, are the most difficult to master, and programming with them is prone
to errors. But pointers are fun too! This month, we’ll look at some puzzles to understand some
interesting aspects of pointers in C.
In the following programs, assume that necessary header to decide, so check the answers first:
files are included. A1. This program will run fine without an assertion failure.
Q1. Will this program result in an assertion failure? Sizes of all pointer types are equal! This might be surprising
to many programmers, but it is easy to understand. Pointers
int main() { signify an address. In general, for a given implementation,
assert(sizeof(void *) == sizeof(int *)); the storage space required for storing an address is the same,
assert(sizeof(int *) == sizeof(int **)); irrespective of the type of pointer used.
} A2. This program results in a compiler error for the
expression ‘i + j’. Why? Pointers signify the address and it
Q2. What will this program print? is illogical to add two addresses. However, you can add an
integer value to an address; for example, an array-based
int main() { address is a pointer and to locate an array element, it is
int iarr[10]; enough to simply add an integer to that address. Pointer
int *i = &iarr[2], *j = &iarr[5]; subtraction is allowed; in this case, for example, ‘i – j’
int *k = i + j; indicates the number of array elements between them, which
int diff = j – i; is equivalent to the expression (&iarr[5] - & iarr[2]), and is
printf(“%d”, diff); always 3, irrespective of the size of int.
} A3. Old C compilers or modern C compilers in K&R C
mode (which refers to pre-ANSI C -- the original C language
Q3. Will this program work? defined by Dennis M. Ritchie) do not have strong type
checking and, hence, they will compile this fine.
int main() { In the underlying implementation, if the size of int and
int i = “C is often unpredictable!”; the size of the pointer are the same, then there is no problem
printf(i); in storing the address of the string literal in integer i. printf
} is a dumb routine and it will interpret the first argument as
a string (in fact, i has an address of a string literal). So, this
Q4. What does the following program print? program might compile and print: “C is often unpredictable!”
A4. Yes, this program will print “Joy”! Note that strncpy
int main() { returns a char* which is the address of the copied string.
char string[10]; Here, strncpy copies three characters and returns that string.
printf(strncpy(string ,”Joy of C”,3)[3] = ‘0’); Then, we do indexing on that returned char* and put the null
} terminator ‘0’ for that string in the index position [3]. The
printf gets “Joy” as the argument and prints it.
Q5. What does this following program print? A5) This program results in a compiler error for the
expression ‘&&i’. The ‘&&’ operator is a logical ‘and’ operator
int main() { and requires two operands. Ignoring this syntax issue, the
// assume that address of i is 0x1234ABCD more important problem is that the attempted expression
int i = 10; is illogical. It is possible to take ‘address of i’ with &i; but
int * ip = &i; address of ‘address of i’ cannot exist!
int **ipp = &&i;
