To calculate grade of a student on the basis of total marks in C++ programming, you have to ask from user to enter marks obtained in 5 subjects. Now add marks of all the 5 subjects and divide it by 5 to get average mark. And based on this average mark, find grade as per the table given above:
// C++ Program to Find Grade of Student // -------codescracker.com------- #include<iostream> using namespace std; int main() { int i; float mark, sum=0, avg; cout<<"Enter Marks obtained in 5 Subjects: "; for(i=0; i<5; i++)
Suppose a program written in language L1 must be executed on a machine running a program running in language L0. What important operation must take place
Question Completion with Options:
a. Translation of the entire L1 program into L0 code
b. Translation of the L0 program into L1 code
c. Creation of a language L3 that interprets L0 instructions
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Answer:
The important operations that must take place in this scenario are:
a. Translation of the entire L1 program into L0 code
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Explanation:
Translation enables decoding to take place. This means that the L1 program is decoded into a language that the L0 program can understand and execute. Without this translation, the higher level language of L1 will not be understood by the machine language of the L0 programs. Translation of a code creates a shared understanding, thereby easing program execution. Code translation is simultaneously accompanied by interpretation.
I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?
a. hard drive is full
b. photos were taken in a different country
c. USB port is broken
d. the file structure of the 2 hard drives are not compatible
The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.
The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.
Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:
JPEGPNGJFIFAny external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.
The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false
Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:
"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

While troubleshooting an Internet connection problem for your network, you restarted the modem and then the router. The router is now communicating with the Internet, which you can confirm by observing the blinking light on the router's WAN indicator. However, now your laptop is not communicating with the router. Order the commands below to fix the problem and confirm connectivity.
a. ping
b. ipconfig /renew
c. nslookup microsoft.com
d. ipconfig /release
Answer:
d. ipconfig /release
b. ipconfig /renew
a. ping
c. nslookup microsoft.com
Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
On a related note, when a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.
I. ipconfig /release
II.. ipconfig /renew
III. ping

A. Encrypt all communications with TLS 13
B. Transition from SNMPv2c to SNMPv3 with AFS-256
C. Enable Secure Shell and disable Telnet
D. Use a password manager with complex passwords
Answer:
Hence the answer is Option A Encrypt all communication with TLS 1 3.
Explanation:
Transportation Layer Security (TLS 1 3)---->TLS stands for Transport Layer Security and is the successor to SSL (Secure Sockets Layer). TLS provides secure communication between web browsers and servers. The connection itself is secure because symmetric cryptography is used to encrypt the transmitted data.
SNMPv3 Security with 256 bit AES encryption is not available for all devices. The net-snmp agent does not support AES256 with SNMPv3.so it is not the correct option.
The best choice is an option a because TLS 1 3 because,
TLS version 1 3 helped in removing all the insecure features such as:
SHA-1
RC4
DES
3DES
AES-CBC

As the first step, load the dataset from airline-safety.csv by defining the load_data function below. Have this function return the following (in order):
1. The entire data frame
2. Total number of rows
3. Total number of columns
def load_data():
# YOUR CODE HERE
df, num_rows, num_cols
Answer:
import pandas as pd
def load_data():
df = pd.read_csv("airline-safety.csv')
num_rows = df.shape[0]
num_cols = df.shape[1]
return df, num_rows, num_cols
Explanation:
Using the pandas python package.
We import the package using the import keyword as pd and we call the pandas methods using the dot(.) notation
pd.read_csv reads the csv data into df variable.
To access the shape of the data which is returned as an array in the format[number of rows, number of columns]
That is ; a data frame with a shape value of [10, 10] has 10 rows and 10 columns.
To access the value of arrays we use square brackets. With values starting with an index of 0 and so on.
The row value is assigned to the variable num_rows and column value assigned to num_cols
A hierarchy chart can be helpful for a. planning the functions of a program b. naming the functions of a program c. showing how the functions of a program relate to each other d. all of the above e. a and c only
Answer:
Hence the correct options are option B and option C.
Explanation:
Hierarchy Chart means top to bottom structure 0f a function or a program or an organization.
Planning the functions of a program means deciding beforehand that what are the functions of a program and what to try to do and when to try to, hierarchy Charts are often helpful In doing/knowing this all.
Showing how the functions of a program relate to every other means what's the connection between two functions for instance if we have a hierarchical chart of a corporation member then we'll have the connection among the members of the team i.e., first, we'll have CEO, then Manager then team/ project lead then team members and by using hierarchical chart ready to " we will be able to identify the connection among them. during a similar way, we will have a relationship among the functions of a program using the hierarchical chart.

An organization needs to integrate with a third-party cloud application. The organization has 15000 users and does not want to allow the cloud provider to query its LDAP authentication server directly. Which of the following is the BEST way for the organization to integrate with the cloud application?
a. Upload a separate list of users and passwords with a batch import.
b. Distribute hardware tokens to the users for authentication to the cloud
c. Implement SAML with the organization's server acting as the identity provider.
d. Configure a RADIUS federation between the organization and the cloud provider
Answer:
The BEST way for the organization to integrate with the cloud application is:
c. Implement SAML with the organization's server acting as the identity provider.
Explanation:
Implementing SAML (Security Assertion Markup Language) integrations will provide more security to the organization (identity provider) as users' credentials are exposed to fewer parties. SAML authenticates the users to the cloud application provider. SAML enables the organization to pass authorization credentials to the service provider by transferring the users' identities to the service provider.
There must be security policies in place to set core standards and requirements when it comes to encrypted data.
a. True
b. False
