assume that name is a variable of type stirng that has been assigned a value write an expression whose value is the last charact

Snezhnost [94]

Answer:

The most straight forward way to do it: in general string are zero index based array of characters, so you need to get the length of the string, subtract one and that will be the last character, some expressions in concrete languages would be:

In Python:

name = "blair"

name[len(name) - 1]

In JavaScript:

name = "blair"

name[name.length - 1]

In C++:

#include <string>

string name = "blair";

name[name.length() - 1];

Suppose I define some structure type ( studentInfo), then I declare an instance of it and I decide to also create a pointer to t

Nookie1986 [14]

Answer:

a. (p*Main).age = 20;

Explanation:

Pointers use ->

where as normal variable use . to access its members

pMain is the pointer.

*pMain is the value inside pMain.

pMain->age = 20;

This statement equals to

(*pMain).age = 20;

Answer is option a.

Greedy Algorithm Design

Alik [6]

Answer:

The algorithm is as follows:

1. Start

2. Get the number of items (n)

3. Get the current price of the n items (a1, a2..... an)

4. Get the possible hiked price of the n items (b1, b2..... bn)

5. Calculate the difference between the current and hiked prices for each item i.e. $d_i = b_i - a_i$

6. Sort the differences in descending order (i.e. from the greatest to the least)

7. Buy items in this order of difference

8. Stop

Explanation:

The algorithm is self-explanatory; however, what it does is that:

It takes a list of the current price of items (say list a)

E.g: $a = [100, 150, 160]$

Then take a list of the hiked price of the items (say list b)

E.g: $b = [110, 180, 165]$

Next, it calculates the difference (d) between corresponding prices $d_i = b_i - a_i$

$d = [(110 - 100),(180-150),(165-160)]$

$d = [10,30,5]$

Sort the difference from greatest to lowest (as the difference is sorted, lists a and b are also sorted)

$d = [30,10,5]$

$a = [150, 100, 160]$

$b = [180, 110, 165]$

If there is no hike up to item k, the couple would have saved (i = 1 to d[k-1])

Assume k = 3

The couple would have saved for 2 item

$Savings = d[1] + d[2]$

$Savings = 30 +10$

$Savings = 40$

The saved amount will then be added to the kth item in list a i.e. a[k](in this case k = 3) in order to buy b[k]

Using the assumed value of k

$a[k] = a[3]$

$a[3] = 160$

$b[3] = 165$

Add the saved amount (40) to a[3]

$New\ Amount = 40 + 160$

$New\ Amount = 200$

This new amount can then be used to buy b[3] i.e. 165, then they save the change for subsequent items

In the word interrupting, the root word rupt means:

Tatiana [17]

A. break, because if you were to interrupt someone mid-conversation you would essentially be 'breaking' their speech. In erupt it seems more like burst but could also be break because the lava erupting from the volcano breaks or damages its surroundings. Just a guess.
