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.

a. 123_name b. &name
c. Name_1 d. #name@
2. Which of the following is not a data type in C?
a. Integer b. Double
c. data d. unsigned
6. 3. How would you assign the value 3.14 to a variable called pi?
a. int pi; b. unsigned pi;
pi=3.14; pi=3.14;
c. string pi; d. float pi;
pi=3.14; pi=3.14;
4. A common mistake for new students is reversing the assignment statement. Suppose you want
to assign the value stored in the variable "pi" to another variable, say "pi2":
i. What is the correct statement?
a. pi2 = pi; b. pi = pi2;
ii. What is the reverse? Is this a valid C statement (even if it gives incorrect results)?
a. pi2 = pi; is a valid C statement if pi b. pi = pi2; is a valid C statement if
is not a constant. pi is not a constant.
iii. What if you wanted to assign a constant value (like 3.1415) to "pi2": What would the correct
statement look like? Would the reverse be a valid or invalid C statement?
a. pi2 = 3.1415; b. 3.1415 = pi2;
The reverse is not a valid statement. The reverse is a valid statement.
5. scanf() is a very powerful function. What does it do?
a. scanf echos characters from the standard input, interprets them according to the
specification in format, and stores the results through the remaining arguments.
b. scanf displays characters from the standard input, interprets them according to the
specification in format, and stores the results through the remaining arguments.
c. scanf is the input analog of printf, providing many of the same conversion facilities
in the opposite direction.
d. scanf is the output analog of printf, providing many of the same conversion
facilities in the opposite direction.
6. Write the scanf() function call that will read into the variable "var":
i. a float ii. an int iii. a double
a. scanf("%f",&var); b. scanf("%f",&var);
scanf("%d",&var); scanf("%d",&var);
scanf("%d", &var); scanf("%lf", &var);
c. scanf("%f",&var); d. scanf("%f",&var);
scanf("%i",&var); scanf("%d",&var);
scanf("%u", &var); scanf("%s", &var);

places.
