Answer: getfenv() is a type of function. Particually a envirotment function. for a lua coding.

Explanation: What this does it goes thourgh line of code in a particular order.

This means. getfenv is used to get the current environment of a function. It returns a table of all the things that function has access to. You can also set the environment of a function to another environment.

Forgot to include examples of where this could be used. Although not very common uses, there are some. In the past Script Builders used getfenv to get the environment of a script, and setfenv to set the environment of a created script’s environment to a fake environment, so they couldn’t affect the real one. They could also inject custom global functions.

Not entirely sure if this uses getfenv or setfenv, but the use in Crazyman32’s AeroGameFramework is making the environment of each module have access to other modules without having to require them, and having access to remotes without having to directly reference them.

9- Write a program in MARIE to add three numbers.

Korvikt [17]

A series of instructions written in a programming language for a computer to follow is referred to as a computer program.

<h3>What is program?</h3>

Software, which also contains documentation and other intangible components, comprises computer programs as one of its components.

The source code of a computer program is the version that can be read by humans. Since computers can only run their native machine instructions, source code needs to be run by another software.

Using the language's compiler, source code may be converted to machine instructions. (An assembler is used to translate programs written in machine language.) An executable is the name of the generated file.

Therefore, A series of instructions written in a programming language for a computer to follow is referred to as a computer program.

Write a script that will read the file, (strip the carriage returns), create a dictionary of names and favorite radishes and cre

amm1812

Answer:

python code below:

names={}#first dictionary for names and favorite

favor={}#radish type and how many are favorite

f=open("raddish.txt")#opening file

for i in f:#for each line

j=i.strip().split("-")#splitting base on -

names[j[0].strip()]=j[1].strip()#getting first dictionary

if j[1].lower().strip() in favor:#counting the favorite elements

favor[j[1].lower().strip()]+=1

else:

favor[j[1].lower().strip()]=1

print ("First Dictionary",names)#printing the names

print("second dictionary:",favor)#printing the favorite numbers

f.close()#closing file

Explanation:

The program was implemented using python programming language.

Its operation is to read the file, (strip the carriage returns), create a dictionary of names and favorite radishes and create a dictionary of each radish type and the number of people who chose that as their favorite.

It returns as output the names of people entered for the Radishes.

This is the formula for the future worth of an investment over time with consistent additional monthly payments and a steady rat

stepladder [879]

Answer:

The code is given in C++ below

Explanation:

#include <iostream>

using namespace std;

int main()

{

float fv,pv,r,k,n,pmt,totalmoneyinvested;

pv=1000.00;

r=6/100;

k=12; //The value of k should be 12 for monthly installments

n=45;

pmt=250;

totalmoneyinvested=pv+(pmt*12*45); //The total money you invested

fv=pv*(1+r/k)*n*k+pmt*((1+r/k)*n*k-1)*(1+r/k)*r/k;

cout<<"Initial Investment:"<<" $"<<pv;

cout<<"\nRate Of Return:6%";

cout<<"\nLength of Time:"<<n<<"year";

cout<<"\nMonthly Payment:"<<" $"<<pmt;

cout<<"\nFinal Amount:"<<" $"<<fv;

cout<<"\nThe Money You Invested Is $"<<totalmoneyinvested<<" And The Final Amount Is $"<<fv;

return 0;

Research 3 distributions that utilize the big data file systems approaches, and summarize the characteristics and provided funct

OlgaM077 [116]

Answer:

Explanation:

1: The three most popular data systems that make use of Big Data file systems approach are:

The HDFS (Hadoop Distributed File System), Apache Spark, and Quantcast File System(QFS).

HDFS is the most popular among these and it makes use of the MapReduce algorithm to perform the data management tasks. It can highly tolerate faults and can run on low-cost hardware. It was written in Java and it is an open-source software.

Apache Spark makes use of Resilient Distributed Data (RDD) protocol. It is much faster and lighter than the HDFS and it can be programmed using a variety of languages such as Java, Scala, Python, etc. Its main advantage over HDFS is that it is highly scalable.

While QFS was developed as an alternative to the HDFS and it is also highly fault-tolerant and with space efficient. It makes use of the Reed-Solomon Error Correction technique to perform the task of data management.

2: The NewSQL databases were developed as a solution to the scalability challenges of the monolithic SQL databases. They were designed to allow multiple nodes in the context of an SQL database without affecting the replication architecture. It worked really well during the starting years of the cloud technology. Some of the databases that make use of New SQL technology are Vitess, Citus, etc.

Vitess was developed as an automatic sharding solution to the MySQL. Every MySQL instance acts as a shard of the overall database and each of these instances uses standard MySQL master-slave replication to ensure higher availability.

While, Citus is a PostgreSQL equivalent of the Vitess. It ensures transparent sharding due to which it accounts for horizontal write scalability to PostgreSQL deployments.

NoSQL database technology was developed to provide a mechanism for the storage and retrieval of data that is modeled in a way other than the tabular relations used in the traditional databases (RDBMS). The most popular database that makes use of the NoSQL technology is MongoDB. It functions as a cross-platform document-oriented database. It is known for its ability to provide high availability of replica sets. A replica set is nothing but a bundle of two or more copies of the data
