What is the purpose of testing a program with sample data or input?
Answer:
testing to make sure that the program is functioning as intended
Explanation:
Sample Data, Test Data, or Inputs are all used with the main purpose of testing to make sure that the program is functioning as intended. The "sample data" needs to provide a very specific output value when inserted into the program. This output value is already known beforehand, therefore if the program outputs the correct "expected" value then the program is functioning correctly.
explain the evolution of computers
Answer:
vintage computers
Computers have changed drastically since the 1930s. AP
From the 1930s to today, the computer has changed dramatically.
The first modern computer was created in the 1930s and was called the Z1, which was followed by large machinery that took up entire rooms.
In the '60s, computers evolved from professional use to personal use, as the first personal computer was introduced to the public.
In the 1980s, Apple introduced its first computer, the Macintosh, and has dominated the computer industry ever since with laptops and tablets.

Although computers seem like a relatively modern invention, computing dates back to the early 1800s.
Throughout computing history, there has not been a lone inventor or a single first computer. The invention of the computer was incremental, with dozens of scientists and mathematicians building on their predecessors. The modern computer, however, can be traced back to the 1930s.
The 1930s marked the beginning of calculating machines, which were considered the first programmable computers.

A calculating machine in the 1930s. AP
Konrad Zuse created what became known as the first programmable computer, the Z1, in 1936 in his parent's living room in Berlin. He assembled metal plates, pins, and old film, creating a machine that could easily add and subtract. Although his early models were destroyed in World War II, Zuse is credited with creating the first digital computer.
In the 1940s, computers took up entire rooms, like the ENIAC, which was once called a "mathematical robot."

A computer room. AP
John Mauchly created the ENIAC during World War II to help the Army with ballistics analytics. The machine could calculate thousands of problems each second. The large-scale ENIAC weighed 30 tons and needed a 1,500-square-foot room to house the 40 cabinets, 6,000 switches, and 18,000 vacuum tubes that comprise the machine.
Some call this invention the beginning of the computer age.
In the 1950s, computers were strictly used for scientific and engineering research, like the JOHNNIAC, which was once described as a "helpful assistant" for mathematicians.
A man working at a computer in the '50s. AP
The JOHNNIAC was completed in 1954 and was used by RAND researchers. The massive machine weighed just over two tons with over 5,000 vacuum tubes. This early computer operated for 13 years or 51,349 hours before being dismantled.
In the 1960s, everything changed when the Programma 101 became the first desktop computer sold to the average consumer.
Programma 101. Pierce Fuller/ Wikimedia Commons
Up until 1965, computers were reserved for mathematicians and engineers in a lab setting. The Programma 101 changed everything, by offering the general public a desktop computer that anyone could use. The 65-pound machine was the size of a typewriter and had 37 keys and a printer built-in.
The Italian invention ushered in the idea of the personal computer that would last to this day.
As personal computers became popular in the 1970s, the Xerox Alto helped pave the way for Steve Jobs' Apple.
Xerox Alto. Francisco Antunes/ Flickr
The Xerox Alto was created in the '70s as a personal computer that could print documents and send emails. What was most notable about the computer was its design, which included a mouse, keyboard, and screen. This state-of-the-art design would later influence Apple designs in the following decade.
The Alto computers were also designed to be kid-friendly so that everyone — no matter the age — could operate a personal computer.
In the '80s, Apple's Macintosh was described as a game-changer for the computer industry.
The Macintosh. Raneko/ Flickr
When Steve Jobs introduced the first Macintosh computer in 1984, Consumer Reports called it a "dazzling display of technical wizardry." Like the Xerox Alto, the Macintosh had a keyboard, a mouse, and a small 9-inch screen. The computer — which weighed in at 22 pounds and cost $2,495 — was applauded for its interface of windows and icons.

The Ruined Man Who Became Rich Again Through a Dream
An adaptation of a story from 1,001 Arabian Nights
Once there lived in the city of Chongqing a very wealthy man who lost all his belongings and his treasures and became very poor. He was so poor that he could only earn his living by laboring day and night. One night, extremely late, he lay down to rest. He was exhausted, dejected, and sick at heart. He fell into a deep sleep and dreamt that a wise old soul came to him and said, "Your fortune is in the city of Beijing; go there and seek it."
The next day, he set out for Beijing. He arrived there deep into the night and he lay down to sleep for a bit in a hostel. Presently, as fate would have it, a company of thieves entered the hostel. They made their way into the house that adjoined the hostel. Soon, the people of the house, aroused by the noise, awoke and cried out, "thieves, thieves!" An alarm was raised and the chief of the police came to their aid with his officers. The robbers made off; but the police entered the hostel and found the man from Chongqing asleep there. They cast him into prison, where they kept him for three days. The chief of police sent for him and said, "Where did you come from?"
"From Chongqing," whispered the man.
"And what brought you to Beijing?" asked the chief.
"I saw in a dream an old soul who said to me, 'Thy fortune is at Beijing; go there at once to find it.' But, when I came here, the fortune that I was promised proved to be an arrest and a jail stay."
The chief of the police laughed until he showed his white, wide, broad teeth. He said to the man from Chongqing, "O man of little wit! Three times have I seen an old soul in a dream who said to me, 'There is a fashionable house in Chongqing, with a fountain in the front garden. Under the fountain there is buried treasure— a great sum of money. Go there and take it.' Of course I did not go. You, on the other hand, you of little wit, have journeyed from place to place, on the faith of a dream, which was but an illusion of sleep."
Then the chief of police gave the man from Chongqing money, saying, "This is to help you get back to your native land."
Now, the house that the chief described was the man's very own house in Chongqing! When he traveled home, he immediately dug underneath the fountain in his garden and discovered a great treasure! He received an abundant fortune in his own yard!

1.1.5 practice: analyzing business culture
a. Recall what you have learned about positive culture and business practices in this lesson. With an
understanding that some things must change with company X, discuss ways in which Company X can
still focus on making changes but also focus on keeping positive culture practices while these changes
are being made. (1 point)
Answer:
A positive culture is an advantage when changes need to be made in the company. Making organisational changes and maintaining a positive culture a mutually complementary rather than mutually exclusive.
In a positive culture environment, people are happy and feel valued. When people feel happy and valued, it makes it easy for management to garner their buy-in cooperation when changes need to be made within the business.
In a culture that is negative, people don't feel valued and as such are always after their own interest rather than that of the company. There is also a tendency to always be on the defensive side of any change that is about to come looking out for one's self rather than what is best for the collective good. In this case, staff are much likely to sabotage new initiatives and changes rather than work to actuate them.
The obverse is true for a business with a positive culture.

Set hasDigit to true if the 3-character passCode contains a digit.
#include
#include
#include
using namespace std;
int main() {
bool hasDigit;
string passCode;
hasDigit = false;
cin >> passCode;
/* Your solution goes here */
if (hasDigit) {
cout << "Has a digit." << endl;
}
else {
cout << "Has no digit." << endl;
}
return 0;
Answer:
Add this code the the /* Your solution goes here */ part of program:
for (int i=0; i<3; i++) { //iterates through the 3-character passCode
if (isdigit(passCode[i])) //uses isdigit() method to check if character is a digit
hasDigit = true; } //sets the value of hasDigit to true when the above if condition evaluates to true
Explanation:
Here is the complete program:
#include <iostream> //to use input output functions
using namespace std; // to identify objects like cin cout
int main() { // start of main function
bool hasDigit; // declares a bool type variable
string passCode; //declares a string type variable to store 3-character passcode
hasDigit = false; // sets the value of hasDigit as false initially
cin >> passCode; // reads the pass code from user
for (int i=0; i<3; i++) { //iterate through the 3 character pass code
if (isdigit(passCode[i])) // checks if any character of the 3-character passcode contains a digit
hasDigit = true; } //sets the value of hasDigit to true if the passcode contains a digit
if (hasDigit) { // if pass code has a digit
cout << "Has a digit." << endl;} //displays this message when passcode has a digit
else { //if pass code does not have a digit
cout << "Has no digit." << endl;} //displays this message when passcode does not have a digit
return 0;}
I will explain the program with an example. Lets say the user enters ab1 as passcode. Then the for loop works as follows:
At first iteration:
i = 0
i<3 is true because i=0
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[0] points to the first character of pass code i.e. a which is not a digit. So the value of i is incremented to 1
At second iteration:
i = 1
i<3 is true because i=1
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[1] points to the second character of pass code i.e. b which is not a digit. So the value of i is incremented to 1
At third iteration:
i = 2
i<3 is true because i=2
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to true because passCode[3] points to the third character of pass code i.e. 1 which is a digit. So the hasDigit = true; statement executes which set hasDigit to true.
Next, the loop breaks at i=3 because value of i is incremented to 1 and the condition i<3 becomes false.
Now the statement if (hasDigit) executes which checks if hasDigit holds. So the value of hasDigit is true hence the output of the program is:
Has a digit.
Where must virtualization be enabled for VM (virtual machine) software to work?

Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, virtualization must be enabled in the BIOS/UEFI for VM (virtual machine) software to work.
BIOS is an acronym for Basic Input/Output System while UEFI is an acronym for Unified Extensible Firmware Interface. BIOS/UEFI are low-level software that serves as an intermediary between the operating systems and the computer's firmware or hardware components. The UEFI is actually an improvement of the BIOS and as such is a modernized software.
Basically, the BIOS/UEFI is a software which is an essential tool or feature which must be enabled to link the virtual machine with the hardware components of the computer.
