What is the significance of C++ programming?The significance of C++ programming may be determined by the fact that it is used for making browsers, applications, and software. Also, C++ is used majorly to make operating systems, and almost all operating systems are built using C++, for example, Mac Os, Windows, Linux, etc.
The programming languages direct a computer to complete these commands over and over again, so people do not have to do the task repeatedly. Instead, the software can do it automatically and accurately.
Therefore, a program that calculates the total and average marks of 4 subjects for 3 students is well-described above.

Problem 1:
Create a Class named Array2D with two instance methods:
public double[] rowAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per row of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{
{ 1, 2, 3, 4, 6},
{ 6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
must yield the following results:
Averages per row 1 : 3.20
Averages per row 2 : 8.20
Averages per row 3 : 13.20
While using this other array:
double[][] testArray =
{
{1, 2},
{4, 5},
{7, 8},
{3, 4}
};
must yield the following results:
Averages per row 1 : 1.50
Averages per row 2 : 4.50
Averages per row 3 : 7.50
Averages per row 4 : 3.50
public double[] colAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per column of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{

must yield the following results:
Averages per column 1: 6.00
Averages per column 2: 7.00
Averages per column 3: 8.00
Averages per column 4: 9.00
Averages per column 5: 11.00

Both have been tested as seen in the example below and output the correct output as per the example in the question. they simply need to be added to whatever code you want.
public static double[] rowAvg(int[][] array) {
double result[] = new double[array.length];
for (int x = 0; x < array.length; x++) {
double average = 0;
for (int y = 0; y < array[x].length; y++) {
average += array[x][y];

average = average / array[x].length;
result[x] = average;
}
return result;

public static double[] colAvg(int[][] array) {
double result[] = new double[array[0].length];
for (int x = 0; x < array[x].length; x++) {

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers.
For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
5 30.0 50.0 10.0 100.0 65.0
the output is:
0.30 0.50 0.10 1.00 0.65
The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.
For coding simplicity, follow every output value by a space, including the last one

An example of a host-based intrusion detection tool is the tripwire program. This is a file integrity checking tool that scans files and directories on the system on a regular basis and notifies the administrator of any changes. It uses a protected database of cryptographic checksums for each file checked and compares this value with that recomputed on each file as it is scanned. It must be configured with a list of files and directories to check and what changes, if any, are permissible to each. It can allow, for example, log files to have new entries appended, but not for existing entries to be changed. What are the advantages and disadvantages of using such a tool? Consider the problem of determining which files should only change rarely, which files may change more often and how, and which change frequently and hence cannot be checked. Hence consider the amount of work in both the configuration of the program and on the system administrator monitoring the responses generated.
Answers
Answer:
The main problem with such a tool would be resource usage
Explanation:
The main problem with such a tool would be resource usage. Such a tool would need a large amount of CPU power in order to check all of the files on the system thoroughly and at a fast enough speed to finish the process before the next cycle starts. Such a program would also have to allocate a large amount of hard drive space since it would need to temporarily save the original versions of these files in order to compare the current file to the original version and determine whether it changed or not. Depending the amount of files in the system the work on configuring the program may be very extensive since each individual file needs to be analyzed to determine whether or not they need to be verified by the program or not. Monitoring responses may not be so time consuming since the program should only warn about changes that have occurred which may be only 10% of the files on a daily basis or less.
