SummaryIn this lab, you complete a partially written C++ program that includes a function named multiplyNumbers() that multiplies two int values to find their product.Three ints should be passed to the multiplyNumbers() function, the two numbers to be multiplied (num1 and num2) should be passed by value, and another int (product) to hold the product of the two numbers should be passed by reference, enabling the multiplyNumbers() function to change its value.The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program.Instructions:Open the source code file named MultiplyTwo.cpp using the code editor.Write the multiplyNumbers() function, the function declaration, and the function call as indicated by the comments.Execute the program by clicking "Run Code."Rewrite the multiplyNumbers() function to pass the two numbers (num1 and num2) by value and to pass product by address.Execute the program. It should generate the same output.// MultiplyTwo.cpp - This program calculates the product of two numbers.// It demonstrates pass by reference and then pass by address.// Input: None// Output: The product of two numbers#include using namespace std;// Write function declaration hereint main(){int num1 = 10;int num2 = 20;int product = 0;// Print value of product before function callcout << "Value of product is: " << product << endl;// Call multiplyNumbers using pass by reference for product// Print value of calculated productcout << num1 << " * " << num2 << " is " << product << endl;return 0;} // End of main function// Write multiplyNumbers function here; use pass by reference for result of multiplication. Then use pass by address.
Answer:
Declare the method prototype using:
void multiplyNumbers(int x, int y,int &product);
Call the function using:
multiplyNumbers(num1, num2,product);
Lastly, the method is as follows:
void multiplyNumbers (int x, int y,int &product) {
product = x * y;
return; }
Explanation:
Declare the method prototype using
void multiplyNumbers(int x, int y,int &product);
Call the function using
multiplyNumbers(num1, num2,product);
The method is as follows; the & written in front of product implies that product is passed by reference
void multiplyNumbers (int x, int y,int &product) {
This calculate the product
product = x * y;
This returns nothing
return; }

The volumes of data collected by contemporary organizations are so huge that they are beyond the ability of typical DBMS to capture, store, and analyze. These big data may be unstructured or semi-structured and are not suitable for relational DBMS products. What are the new technologies developed to handle the big data
Answer:
Some of the new technologies developed to handle the big data are as follows:
1. In-memory Databases
2. Blockchain
3. NoSQL Databases
4. Edge Computing
5. Streaming Analytics.
6. Artificial Intelligence
Explanation:
Some of the new technologies developed to handle the big data are explained as follows:
1. In-memory Databases: This allows for rapid and easy access to data and analytics, which can be used to inform a variety of business choices. In-memory computing provides the information required to improve marketing, finances, and operations efficiency.
2. Blockchain: Blockchain is the distributed database technology that underpins the Bitcoin digital currency, and it's a darling among forward-thinking analysts and venture capitalists. The distinctive feature of a blockchain database is that data can't be erased or changed after it's been written. Furthermore, it is extremely secure, making it a perfect solution for sensitive industries such as retail, insurance, health care, banking, and among others.
3. NoSQL Databases: NoSQL databases are used to store unstructured data and offer quick performance. This implies it can handle a wide range of data formats in high volumes while remaining flexible. MongoDB, Redis, and Cassandra are examples of NoSQL databases.
4. Edge Computing: Edge computing systems evaluate data very near to where it was originated — at the network's edge — rather than sending it to a centralized server for analysis. An edge-computing system has the advantage of minimizing the quantity of data that must be transferred over the network, therefore lowering network traffic and expenses.
5. Streaming Analytics: By analyzing data as it is created, Streaming Analytics allows for faster and faster access to insights. Streaming Analytics can also take data from a variety of sources, evaluate it, and offer insights almost instantly.
6. Artificial Intelligence: Artificial intelligence has the ability to transform data analytics by learning (from previous analytic activities) and improving the speed and accuracy of outputs over time. Artificial intelligence has the ability to make accurate future predictions based on current events with vast amounts of data to draw from, as well as analytic results from previous inquiries.

Discuss the impact of Python and other open source programming languages on electronic health records and the health care industry. What are the advantages of using open-source programming
Answer:
Explanation:
Python itself has had an enormous impact on all types of industries including the health care industry. This is mainly due to its ability to easily implement data analysis techniques and artificial intelligence. These combined allow developers to implement artificial intelligence that analyzes large sets of data to pinpoint interesting patterns, which can save lives and detect at-risk individuals using health care records. This is all made possible because it is an open-source language. This means that anyone can use it without having to pay for it. This basically allows anyone to build amazing new features and software without having to worry about gathering the money to pay for licensing fees.
There are several types of software development methods, but almost all of them are based on the ________ model.
Answer:
Waterfall
Explanation:
The waterfall model development strategy may be classed as a flexible design architecture exhibiting a linear operational sequence with each phase being largely dependent on the preceeding phase. Each phase of the waterfall has clearly defined task ; usually starting with the requirement phase where use cases and required docs are gathered, then the design, which caters for the software architecture, the the implementation (which is the main software build) followed by verification and maintainance.
We can see that the waterfall method is sequential and not extremely complex as it follows an entirely linear process.

Consider the following statements, taken from three different Jack programs. In each one of these programs, the identifier foo represents a different thing: let x = 5 + foo - a // program 1. Here foo represents a simple variable. let y = foo[12] - 3 // program 2. Here foo represents an array. let z = 2 * foo.val() // program 3. Here foo represents an object. Suppose that we are parsing any one of these statements (we don’t know which), and that the current token is foo. What kind of parser do we need to determine if we have a simple variable, an array reference or a method call?
Answer:
instanceOf
Explanation:
The parser that would be best suited for this scenario would be the instanceOf keyword, which is part of the javaParser class. This keyword allows you to check if a variable is a simple variable, an array reference or a method call through an IF statement. If it is equal to the compared type it will return a boolean value of True, otherwise it will return False. This keyword is used in Java and Javascript to check the type of the variables in scenarios such as this one.

how do computers help us with our homework
xD I don't know if you said this as a joke, or if you're serious, but here:
A computer can be a helpful tool to complete your homework by giving you access to countless sources of information, it can also provide you with educational games which can enhance a child's learning ability by presenting learning as something fun and interactive as opposed to boring loads of repeated work which barely stimulate learning at all. But keep in mind that a computer can also take the opposite effect on a child's brain, and can gradually turn into addiction.

Azzam is reviewing a paper he just wrote about kinetic friction for his physics class. On the third page, he realizes that every time he wrote "coefficient of friction," he should have written "coefficient of kinetic friction." He uses the Find and Replace tool and clicks on "Replace All" to fix the issue, but then when prints out the paper, he sees "coefficient of friction" in the first paragraph. What is most likely the reason why the phrase was not fixed? Azzam used Find and Replace instead of the Spell Checker. O Azzam clicked "Replace All" instead of "Replace." O Azzam used the tool while he was on the third page. Azzam did not set up the proper printing options.
Answer: Azzam used the tool while he was on the third page
Explanation:
The most likely the reason why the phrase was not fixed is because Azzam used the tool while he was on the third page.
This can be infered from the information given when we're told that he uses the Find and Replace tool and clicks on "Replace All" to fix the issue with regards to the error that he made and thus was done from the third page. Therefore, the tool might not have worked for the first page.

For a processor with primary caches only, an instruction cache miss rate of 1%, a data cache miss rate of 5%, a instruction mix of 30% data accesses, and a cache miss penalty of 80 cycles, what will be the contribution to total CPI from the cache misses
Answer:
2
Explanation:
Instruction cache miss rate = 1% = 0.01
Data cache miss rate = 5% = 0.05
data access Instruction mix = 30% = 0.3
Cache miss penalty = 80 cycles
Determine the contribution to total CPI from the cache misses
Assume cache access time = 1 clock cycle
CpI ( average ) = 1 + (0.01 * 0.7 + 0.05 * 0.3) * 80 = 2.76
∴ contribution to total CPI from cache miss = 2.76 - 0.76 = 2
