TASK DEFINITION: Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.
PROBLEM: How to describe a person in a word who keeps mentioning about his own life story or about himself for every topic that is being conversed? Be it interesting or boring, he has the ability to pick out something that has happened to him or he himself creates a chance to talk about himself. Edit: The person is not selfish. He does care for others. I am just saying that the person relates everything to his life and talks about it, that too not even in a conceited way. This person is experienced enough to relate everything to things that has happened to him.

SOLUTION: Self-Absorbed This is similar to self-centered, but perhaps has less of a negative connotation. A person who talks about themselves a lot may simply be introverted, and socially awkward, and therefore not have a lot else to talk about. They may also try to give themselves a sense of social relevance, not realising that it is actually counter-productive.

PROBLEM: I believe there is a term for a person who uses 'expert sounding' terminology and exudes confidence, even when their actual abilities are significantly short of their 'presentation'. Using 'wine' a subject.... if a person described a taste as: Magnificent bouquet, the esters resonate with hints of mulberry and asparagus. This must be an oak-matured red from Bordeaux. Perhaps.... 2003 vintage, that was a year when unusual rainfall produced an outstanding crop that had the same rich tannins. A person describing the wine like that has apparent confidence, apparent technical expertise, and so on. Yet, if he was a fraud, and knew nothing about wines, and the 'wine' was really vinegar.... what would you call that person? Additionally, this would not be a one-off thing. This would be a person who consistently 'bamboozles' people, and only when you dig below the posturing, or put them in the company of a 'real' expert, do you see the reality. A fraud, a cheat, an imposter. Those would be true, but I'm sure there's a word which also covers the confidence, charisma, and presentation style too. I just can't think of it.

SOLUTION: My first thought for this would be charlatan:- A person who makes elaborate, fraudulent, and often voluble claims to skill or knowledge; a quack or fraud. [American Heritage Dictionary via The Free Dictionary] Another possibility would be mountebank:- a boastful unscrupulous pretender [Merriam-Webster]

PROBLEM: From Wikipedia: In the expression a b = c, a is called the dividend or numerator, b the divisor or denominator and the result c is called the quotient. What's most common (in the context of programming)? dividend/divisor numerator/denominator.

SOLUTION:
Dividend and divisor are terms commonly associated with long division while numerator and denominator are the preferred terms when working with fractions. Operators, operands, parameters, and arguments are usually the terms employed in programming. If any of the OP's listed terms are at all utilised, it will very likely be numerator and denominator (in their mathematical sense).
