Answer:

The answer is "C"

Explanation:

In the computer system, the data which separates a data object into relevant concepts is known as data representation. In the representation of data, it uses the binary digits, that are in the form of '0 and 1'. It is used by computers to store information and these numbers are also known as bits, and wrong choices can be defines as follows:

Answer:

many-to-many

The blockchain technology would be classified as a Question Mark strategic business unit (SBU)

Explanation:

The Boston Consulting Group Matrix was first developed towards the end of the nineteenth century for use in analysing the performance and classifying products and business units.

This tool is still very relevant today.

The Matrix is made up of four quadrants:

Top Left - Question Mark

Top Right - Star

Bottom Left -  Dog

Bottom Right -  Cashcow

A Question Mark product or business unit is one which at the onset has a very little market share in an environment with a high growth rate. It is at the onset also characterised by losses and will need more time and money for it to bloom. If invested and nurtured can become a start and then a cash cow. There is also a risk that it will end up a white elephant business unit or product if it is not nurtured properly thus leading to losses.

Answer:

a. SaaS

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.

Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service.

Answer:  

Here it the solution statement:  

searchResult = strchr(personName, searchChar);  

This statement uses strchr function which is used to find the occurrence of a character (searchChar) in a string (personName). The result is assigned to searchResult.

Headerfile cstring is included in order to use this method.

Explanation:  

Here is the complete program

#include<iostream> //to use input output functions  

#include <cstring> //to use strchr function  

using namespace std; //to access objects like cin cout  

int main() { // start of main() function body  

  char personName[100]; //char type array that holds person name  

  char searchChar; //stores character to be searched in personName

  char* searchResult = nullptr; // pointer. This statement is same as searchResult  = NULL    

  cin.getline(personName, 100); //reads the input string i.e. person name  

  cin >> searchChar;    // reads the value of searchChar which is the character to be searched in personName  

  /* Your solution goes here */  

  searchResult = strchr(personName, searchChar); //find the first occurrence of a searchChar in personName  

  if (searchResult != nullptr) //if searchResult is not equal to nullptr  

  {cout << "Character found." << endl;} //displays character found

  else //if searchResult is equal to null  

  {cout << "Character not found." << endl;} // displays Character not found  

  return 0;}  

For example the user enters the following string as personName  

Albert Johnson  

and user enters the searchChar as:  

J

Then the strchr() searches the first occurrence of J in AlbertJohnson.  

The above program gives the following output:  

Character found.

Answer:

The program in Python is as follows:

name = input("Name: ")

course = input("Course: ")

month = input("Month: ")

day = input("Day: ")

year = input("Year: ")

ddate = (month+"/"+day+"/"+year).replace(" ", "")

print("My name is ",name)

print("I have taken  ",course)

print("Today's date is ",ddate)

Explanation:

This line prompts user for name

name = input("Name: ")

This line prompts user for course classes taken

course = input("Course: ")

This line prompts user for month

month = input("Month: ")

This line prompts user for day

day = input("Day: ")

This line prompts user for year

year = input("Year: ")

This line calculates the date and remove all blank spaces

ddate = (month+"/"+day+"/"+year).replace(" ", "")

The next three lines print the user inputs

print("My name is ",name)

print("I have taken  ",course)

print("Today's date is ",ddate)

Answer:

(b) int **arr = new int*[10];

Explanation:

An array of pointers is simply an array containing pointer variables. These pointer variables may be Strings, integers, doubles e.t.c

To declare such arrays of pointers, for example, of integers, in C++, we write;

int **arr = new int*[10];

The left hand side of the above code snippet i.e int ** arr, suggests that arr is a pointer that points to a pointer to integer variables.

The right hand side i.e new int* [10], creates a new array of 10 integer pointer variables.

Now, put together, int **arr = new int*[10] will create/declare an array of pointers of integers having a size of 10.
