How do we access a global variable in nested functions?

How do we access a global variable in nested functions? Correct Answer Declare the variable as global

Any global variable, in the primary function, if required to be accessed by a nested function- the variable needs to be declared with the global keyword within the function which requires access to it. This allows sharing the variable amongst the primary and other functions. If the variable is declared without using the global keyword, the variable might bring an error to the function.

Jio is a big shot at reducing the cost of Internet access in India. The U.S., despite being the richest country in the world, lags far behind in terms of cost and penetration of Internet access. Cheap access to the Internet is an important step in bridging the access gap – access to good education, good healthcare, etc. But the market reaction to Jio is similar to the U.S. markets reaction to firms announcing their intention to diversify. (A)The final group of losers is the current shareholders of RIL. On announcement of Jio, the stock price of RIL fell. (B) It shows that the markets short-term reaction is usually proven correct in the long-run. (C) On losing end, the first groups of losers are the shareholders of other telecom companies. (D)The large amount of revenue the Government of India gets from auctioning off the nations natural resources is not necessarily a good thing because the Government does not have a stellar track record when it comes to spending the money. A large fraction of Government spending is wasted. (E) The second loser is the Government of India. The big money the Indian Government was raking in selling cellular bandwidth was actually coming from the pockets of the cellular consumers. (F)The first obvious winners of this scheme are customers. (G) The second winner is Mr. Ambani; he can potentially make a lasting impact as the man who brought Internet to millions of Indians.

Statement I The product of coefficient of correlation, standard deviation of variable 'X' and Standard deviation of variable 'Y' gives the measure of covariance between X and Y variables.
Statement II The product of coefficient of correlation between X and Y variables and the ratio between standard deviation of X variable to standard deviation of Y variable measures the slope of the regression line of X on Y variable.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: For users, Facebook's revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next? For the owners of the affected accounts, and of another 40 million that Facebook considered at risk, the first order of business may be a simple one: sign back into the app. Facebook logged everyone out of all 90 million accounts in order to reset digital keys the hackers had stolen - keys normally used to keep users logged in, but which could also give outsiders full control of the compromised accounts.  Which of the following points do not capture the negligence of Facebook in the most appropriate manner? Arguments: I. What Facebook knows so far is that hackers got access to the 50 million accounts by exploiting three distinct bugs in Facebook's code that allowed them to steal those digital keys, technically known as ‘access tokens’. The company says it has fixed the bugs.  II. The hack is the latest setback for Facebook during a tumultuous year of security problems and privacy issues . So far, though, none of these issues have significantly shaken the confidence of the company's 2 billion global users.  III. One of the bugs was more than a year old and affected how the ‘View As’ feature interacted with Facebook's video uploading feature for posting ‘happy birthday’ messages. But it wasn't until mid-September that Facebook noticed an uptick in unusual activity, and not until this week that it learned of the attack.
Which of the following are true? (i) A programming language option does not permit global variables of any king and has no nesting of procedures/functions, but permits recursion can be implemented with static storage allocation (ii) Multi-level access link (or display) arrangement is needed to arrange activation records-only if the programming language being implemented has nesting of procedures/function (iii) Recursion in programming languages cannot be implemented with dynamic storage allocation (iv) Nesting of procedures/functions and recursion require a dynamic heap allocation scheme and cannot be implemented with a stack-based allocation scheme for activation records (v) Languages which permit a function to return a function as its result cannot be implemented with a stack-based storage allocation scheme for activation records.
