The purpose of __________________ is to isolate the behavior of a given component of software. It is an excellent tool for software validation testing.a. white box testingb. special box testingc. class box testingd. black-box testing
Answer:
d.) black-box testing
Explanation:
Software testing can be regarded as procedures/process engage in the verification of a system, it helps in detection of failure in the software, then after knowing the defect , then it can be corrected. Black Box Testing can be regarded as a type of software testing method whereby internal structure as well as design of the item under test is not known by one testing it. In this testing internal structure of code/ program is unknown when testing the software, it is very useful in checking functionality of a particular application. Some of the black box testing techniques commonly used are; Equivalence Partitioning, Cause effect graphing as well as Boundary value analysis. It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.

Write a program that does the following.
Create a dynamic two dimensional squarearray of unsigned integers (array_one). Prompt the user to enter the number of rows and columns they want (maximum of 30) (rows and columns must be the same for a square array)
Pass the array to a function that will initialize the two dimensional array to random numbers between 0 and 4000 using the rand() library function. Here is the kicker: The array cannot have any repeated values!
Create another dynamic two dimensional array of the same size (array_transpose)
Pass both arrays to a function that will generate the transpose of array_one returning the values in array_transpose. (If you don’t already know the transpose swaps the rows and columns of an array.) Example: Suppose you have a 4 x 4 array of numbers (array_one). The transpose is shown below (array_transpose)
Array One Array Transpose
1 2 3 4 1 5 9 13
5 6 7 8 2 6 10 14
9 10 11 12 3 7 11 15
13 14 15 16 4 8 12 16
Pass each array to a print_array function that will print (to the screen or a file) the results of a test case with a 20 by 20 array.
Answer:
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int n;
cout<< "Enter the row and column length: ";
cin>> n;
int array_one[n][n];
int array_transpose[n][n];
for (int i = 0; i < n; i++){
for (int j= 0; j < n; j++){
srand((unsigned) time(0));
array_one[i][j] = (rand() % 4000)
array_transpose[j][i] = array_one[i][j];
}
}
}
Explanation:
The C source code has three variables, 'array_one', array_transpose' (both of which are square 2-dimensional arrays), and 'n' which is the row and column length.
The program loops n time for each nth number of the n size to assign value to the two-dimensional array_one. the assign values to the array_transpose, reverse the 'i' and 'j' values to the two for statements for array_one to 'j' and 'i'.

Which of the following is NOT true?
a. The process provides the macro steps
b. Methodologies provide micro steps that never transcends the macro steps.
c. Methodologies provide micro steps that sometimes may transcend the macro steps.
d. A methodology is a prescribed set of steps to accomplish a task.
Answer:
b. Methodologies provide micro-steps that never transcends the macro steps.
Explanation:
Methodologies are a series of methods, processes, or steps in completing or executing a project. Projects can be divided into macro steps or processes and these macro steps can be divided into several micro-steps. This means that, in methodology, micro-steps always transcends to a macro-step.
Net has a class that can generate parallel threads without the programmer needing to be overly burdened with thread maintenance. One method from this class that we examined in this course is:_________.
A. Thread.Invoke()
B. Cast.All
C. Parallel.For
D. Thread.Cast()
E. ThreadPool.Invoke()
Answer:
The correct answer is option C "Parallel.For"
Explanation:
Parallel.For for the most part work best on external loop as opposed to inward circles. This is on the grounds that with the previous, you're offering bigger lumps of work to parallelize, weakening the administration overhead. Parallelizing both inward and external loops is typically superfluous. In the accompanying model, we'd commonly need in excess of 100 cores to profit by the inward parallelization.
Designers use the Parallel class for a situation alluded to as information parallelism. This is where a similar activity is acted in equal on various things. The most widely recognized illustration of this is in an array which should be followed up on. Using the Parallel class, you can use this procedure/operation on any sort of iteration, in Parallel.
Write a method that draws a circle and a square that is centered in a DrawingPanel. The method will take in the width and height (they are the same for both the circle and square) and a Graphics object as parameters
IN java
current code: turn it into a method along with the main method
import java.awt.*;
public class Graphics {
static final int WIDTH = 300;
static final int HEIGHT = 200;
public static void drawGraphics () {
}
public static void main(String []args) {
DrawingPanel2 draw = new DrawingPanel2(WIDTH,HEIGHT); // Make a DrawginPanel2 of size 300 by 200.
Graphics2D g = draw.getGraphics(); // gets graphics from DrawingPanel so you can draw
g.setColor(Color.RED);
g.fillRect(45, 30, 200, 150);
g.setColor(Color.BLUE);
g.fillOval(70, 30, 150, 150);
}
}
Answer:
public static void drawGraphics (Graphics g, int width, int height) {
int r = Math.round(width/2);
int x = 45;
int y = 30;
g.setColor(Color.RED);
g.fillRect(x, y, width, height);
g.setColor(Color.BLUE);
g.fillOval(Math.round(x/2), Math.round(y/2), r, r);
}
Explanation:
The Java method "drawGraphics" of the Graphics class accepts draws a square with the "fillRect()" method of the Graphics class object and at its center, a circular path is drawn as well.

An array, numbers, of integers is filled with 100 random numbers whose values are greater than 10 and less than 255. You DO NOT have to write code to generate the random numbers. Write the code to count how many of the even numbers in the array are greater than 10 and less than 157 (inclusive).
Answer:
int counter = 0;
for(int i =0;i<100;i++){
if(myarr[i]%2==0){
if(myarr[i] > 10 && myarr[i]<157){
counter++;
}
}
}
cout<<counter;
Explanation:
The question is answered using c++ and it assumes that the array name is myarr
This line initializes counter to 0
int counter = 0;
This iterates through the array
for(int i =0;i<100;i++){
This checks if current array element is even number
if(myarr[i]%2==0){
If the above condition is true; This checks if the array element is within the range of 10 and 157 (inclusive)
if(myarr[i] >= 10 && myarr[i]=<157){
If yes, the counter is increased by 1
counter++;
}
}
}
This prints the total counter number
cout<<counter;
The Bellman-Ford algorithm for the shortest path problem with negative edge weights will report that there exists a negative cycle if at least one edge can still be relaxed after performing nm times of relaxations. The algorithm, however, does not specify which cycle is a negative cycle. Design an algorithm to report one such cycle if it exists. You should make your algorithm runs as fast as possible.
Answer:
- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.
- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".
- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.
- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.
Explanation:
The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.

Which important aspect of the Roman Empire did the barbarians destroy?
Answer:
centers of learning
Explanation:
Under the leadership of Emperor Valens, Rome was already having financial hardships. This meant that it didn't have enough money left to repair its empire nor to strengthen it against invaders. Soon, the barbarians such as the Franks, Huns, Saxons, etc. started attacking Rome. They spent a lot of time destroying the outer regions of the empire because they were also at war with each other. They penetrated Rome and it soon fell. The barbarians didn't only destroy the cities but they also destroyed the "centers of learning." Roman people were known to value education. With the fall of the Roman Empire, so did education and sophisticated architectures follow.

What is the effective memory access time in clock cycles if the hit ratio is 90%
Answer:
6.5
Explanation:
The formula to calculate the efficiency is;
= (cache-click-cycle x hit ratio) + ( memory-clock-cycle x 1 - hit ratio)
= (5 x 0.9) + ( 20 x 0.1)
= 4.5 + 2
= 6.5
In this exercise we have to use the knowledge of efficiency, in this way, using the data already informed, we can say that the result of this is:
6.5 effective memory
In this exercise, it was informed that some conditions must be established, that is:
Hit radio: 90%Memory: 20Cache: 5
The formula to calculate the efficiency is;
[tex]efficiency= ((cache-click-cycle)(hit \ ratio)) + ( (memory-clock-cycle)(1 - hit \ ratio))[/tex]
Substituting the known values in the formula above, we find that:
[tex]= (5)(0.9) + ( 20)(0.1)\\= 4.5 + 2\\= 6.5[/tex]

The function's only behavior should be to return the sum of array userVals' elements. What common error does the function make?
Assume userVals always has exactly 10 elements.
int SumArray Elements(int uservals[]) {
for (i = 1; i <10; ++i) {
userVals[i] = userVals[i] + userVals[i - 1]; } return userVals[i]; }
A. Attempts to access an invalid element.
B. Omits the first element from the sum.
C. Modifies userVals' elements.
D. Omits the last element from the sum.
Answer:
A. Attempts to access an invalid element.
Explanation:
The C program above is supposed to loops 10 times to get the total of the userVal's element, but the loop is assigning the cumulative sum of the to each nth index of the userVal array. Although the cumulative total of the array is assigned to the last index, the return statement is attempting to return an invalid element (since i is local only to the for loop statement). The program should return the userVal[9] instead.
