Static Keyword Static is a keyword in C++ used to give special chara.pdfKUNALHARCHANDANI1
Static Keyword Static is a keyword in C++ used to give special characteristics to an element.
Static elements are allocated storage only once in a program lifetime in static storage area. And
they have a scope till the program lifetime. Static Keyword can be used with following, Static
variable in functions Static Class Objects Static member Variable in class Static Methods in class
Static variables inside Functions Static variables when used inside function are initialized only
once, and then they hold there value even through function calls. These static variables are stored
on static storage area , not in stack. void counter() { static int count=0; cout << count++; } int
main(0 { for(int i=0;i<5;i++) { counter(); } } Output : 0 1 2 3 4 Let\'s se the same program\'s
output without using static variable. void counter() { int count=0; cout << count++; } int main(0
{ for(int i=0;i<5;i++) { counter(); } } Output : 0 0 0 0 0 If we do not use static keyword, the
variable count, is reinitialized everytime when counter() function is called, and gets destroyed
each time when counter() functions ends. But, if we make it static, once initialized count will
have a scope till the end of main() function and it will carry its value through function calls too.
If you don\'t initialize a static variable, they are by default initialized to zero. Static class Objects
Static keyword works in the same way for class objects too. Objects declared static are allocated
storage in static storage area, and have scope till the end of program. Static objects are also
initialized using constructors like other normal objects. Assignment to zero, on using static
keyword is only for primitive datatypes, not for user defined datatypes. class Abc { int i; public:
Abc() { i=0; cout << \"constructor\"; } ~Abc() { cout << \"destructor\"; } }; void f() { static Abc
obj; } int main() { int x=0; if(x==0) { f(); } cout << \"END\"; } Output : constructor END
destructor You must be thinking, why was destructor not called upon the end of the scope of if
condition. This is because object was static, which has scope till the program lifetime, hence
destructor for this object was called when main() exits. Static data member in class Static data
members of class are those members which are shared by all the objects. Static data member has
a single piece of storage, and is not available as separate copy with each object, like other non-
static data members. Static member variables (data members) are not initialied using constructor,
because these are not dependent on object initialization. Also, it must be initialized explicitly,
always outside the class. If not initialized, Linker will give error. class X { static int i; public:
X(){}; }; int X::i=1; int main() { X obj; cout << obj.i; // prints value of i } Once the definition for
static data member is made, user cannot redefine it. Though, arithmetic operations can be
performed on it. Static Member Functions These functions work for the .

viruses which have single strande DNA in their genome come under cat.pdfKUNALHARCHANDANI1
viruses which have single strande DNA in their genome come under category of paroviridae
which generally includes animal pathogens. These viruses when infect the host, the single
stranded DNA is first converted into double stranded DNA, and then using the host machinary
for transcription, ds DNA transcribes into viral mRNA.
For transcription, RNA polymerase, transcription factors , enzymes are acquired from the host
and divided into initiation, elongation and termaination. For gene expression in viruses
transcription is generally not coupled with translation in ssDNA virus. The virus instructs
transcription machinary to make viral components in the host cell.

This word problem is about a triangle whose perimeter is 47 miles. S.pdfKUNALHARCHANDANI1
This word problem is about a triangle whose perimeter is 47 miles. Since it\'s asking to find the
length of each side, then there are 3 unknowns. So here\'s what we do:
Let the variables S1 be the length of side 1 in miles,
S2 be the length of side 2 in miles,
and S3 be the length of side 3 in miles.
Now, the next thing to do with these variables is to set up equations that follow the word
problem. Here they are as follows:
S1+S2+S3=47 the perimeter of the triangle by adding the lengths of all three sides
S1=(2*S2)-5 1st side (represented by S1) is (represented by =) 5 less (represented by -5) than
twice the 2nd side (represented by 2*S2).
S3=S1+2 3rd side (represented by S3) is 2 more (represented by +2) than the 1st side.
Next, since we have more than one unknown, we should express one equation in terms of one
variable. Since only one variable has a coefficient which is S2 in the term, 2*S2, I suggest that
we express the other variable equations of S1 and S3 in terms of S2. Here\'s how it goes:
S1=(2*S2)-5 as S1 is already expressed in terms of S2
S3=S1+2=[(2*S2)-5]+2 I plugged in the S1 equation to express S3 in terms of S2.
=(2*S2)-5+2 I combined like terms.
=(2*S2)-3.
Now that I have expressed both S1 and S3 in terms of S2, I can plug those equations into that for
the triangle perimeter:
[(2*S2)-5]+S2+[(2*S2)-3]=47
(2*S2)-5+S2+(2*S2)-3=47 Again, I combined like terms.
(5*S2)-8=47
+8=+8 I added 8 on both sides of the equation to eliminate -8 on the left side.
5*S2=55
5*S2/5=55/5
S2=11
S1=(2*11)-5=22-5=17 Now that I have found the value of S2, I can plug it into the S1 equation.
S3=17+2=19 Now that I have found the value of S1, I can plug it into the S3 equation.
So now here are the lengths of each side of the triangle. Side 1 is 17 miles, side 2 is 11 miles, and
side 3 is 19 miles.
Solution
This word problem is about a triangle whose perimeter is 47 miles. Since it\'s asking to find the

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
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.
