Answer:
SELECT TECHNAME, EMPNUM, YEAR FROM EMPLOYEE ORDER BY YEAR DESC
Explanation:
The table definition is not given;
However, I'll make the following assumptions
Table Name:
Employee
Columns:
Technician name will be represented with Techname
Employee number will be represented with Empnum
Year Hired will be represented with Year
Having said that; the sql code is as follows:
SELECT TECHNAME, EMPNUM, YEAR FROM EMPLOYEE ORDER BY YEAR DESC
The newest year hired will be the largest of the years;
Take for instance:
An employee hired in 2020 is new compared to an employee hired in 2019
This implies that the year has to be sorted in descending order to maintain the from newest to oldest.
Which of the following is considered a basic task in the context of computer operations? a. Connecting to the Internet b. Natural language processing c. Word processing d. Logical operations
Answer:
The answer is "Option d".
Explanation:
The performing function into the computer is made up of three basic functions, that are: logical, arithmetical, and memory processes, in which the logical process or function is a particular symbol or expression, that links two or more knowledge sentences, and the incorrect choices can be explained as follows:
In Option a, It is wrong because it can't provide the basic tasks.In Option b, It an algorithm, that's why it is incorrect.In Option c, It is a software, which is used to provide editing on text, that's why it is incorrect.A task which is considered as a basic task in the context of computer operations is: D.

2.2-2 Consider sorting numbers stored in array by first finding the smallest element n A of and exchanging it with the element in . Then find the second smallest A AOE1 element of A, and exchange it with . Continue in this manner for the firs AOE2 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the firs elements, rather than for all elements? Give the best-case n 1 n and worst-case running times of selection sort in ‚-notation.
Answer:
Follows are the explanation of the choices:
Explanation:
Following are the Pseudocode for selection sort:
for j = 0 to k-1 do:
SS = i
For l = i + 1 to k-1 do:
If X(l) < X(SS)
SS= l
End-If
End-For
T = X(j)
X(j) = X(SS)
X(SS) = T
End-For
Following are the description of Loop invariants:
The subarray A[1..j−1] includes the lowest of the j−1 components, ordered into a non-decreasing order, only at beginning of the iteration of its outer for loop.
A[min] is the least amount in subarray A[j.. l−1] only at beginning of the each loop-inner iterations.
Following are the explanation for third question:
Throughout the final step, two elements were left to evaluate their algorithm. Its smaller in A[k-1] would be placed as well as the larger in A[k]. One last is the large and medium component of its sequence because most and the last two components an outer loop invariant has been filtered by the previous version. When we do this n times, its end is a repetitive, one element-sorting phase.
Following is the description of choosing best-case and worst-case in run- time:
The body the if has never been activated whenever the best case time is the list is resolved. This number of transactions are especially in comparison also as a procedure, that will be (n-1)(((n+2)/2)+4).
A structure iterator at every point in the worst case that array is reversed, that doubles its sequence of iterations in the inner loop, that is:(n−1)(n+6) Since both of them take timeΘ(n2).
In a C++ program, one and two are double variables and input values are 10.5 and 30.6. After statement cin >> one >> two; executes________ a) one = 10.5, two = 10.5 b) one = 11, two = 31 c) one = 30.6, two = 30.6 d) one = 10.5, two = 30.6
Answer:
The answer is "Option d"
Explanation:
In the given C++ program code, It is defined, that two double type variable "one and two" is defined, that holds the two double value that is "10.5 and 30.6".
In this code, it uses the "cin" method for input values from the user ends, when we execute this code, it provides the console screen, that inputs the double type value from the user side, and other given choices were wrong because it holds different values.
Write a program that reads the subtotal and the gratuity rate, then computes the gratuity and total.For example, if the user enters 10 for subtotal and 15% for gratuity rate,the program displays $1.5 as gratuity and $11.5 as total.Sample RunEnter the subtotal and a gratuity rate: 10 15The gratuity is $1.5 and total is $11.5Class Name: Exercise02_05
Answer:
Using Javascript,
function calTotal( subtotal, gratuity){
gratuityValue = subtotal * (gratuity/100)
total = subtotal + gratuityValue
console.log( "gratuity: ", gratuityValue , "\nTotal: ", total)
}
Explanation:
The javascript function above is able to collect two parameters subtotal and gratuity rate in percentage and calculate the total and gratuity value, and displays it on the console.

Which XP practice prescribes that "the code [always be] written by two programmers at one machine"?.
Answer:
Pair Programming
Explanation:
In Extreme Programming XP, pair programming is a practice in which two programmers work together in a pair at one machine, when writing a code.
One of the two programmers is called the "driver" or developer who writes the code and supervises all the changes made to the program.
The other one is called an "navigator" or observer who provides ideas on how the program should be written, observes or reviews it the program, identify the issues or errors in the code, help in code simplifications.
The two developers implements the program, do coding, review the program and check each other's work. They both are required to be equally skilled in order to implement and test the code. This improves the process of the software development. By working in a pair and reviewing and testing the code together, they develop a better code.
