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;
Answers
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.

You resurrected an old worksheet. It appears to contain most of the information that you need, but not all of it. Which step should you take next?
a) Check for data you have previously hidden.
b) Make the columns wider.
c) Check that the worksheet is not Read-Only.
d) Change the format to reduce the font size.
Answers
Answer:
a)
Explanation:
Since the worksheet contains most of the data that you need, there is a decent possibility that it also contains the data that you are missing. Therefore, you should check for data you have previously hidden. Sometimes, some data in a worksheet may become irrelevant in a given moment, and instead of deleting it since it may be useful later most people tend to make that data hidden. So checking for previously hidden data may be the best solution in this scenario.

I need to send black-and-white images in a print-ready format. Therefore, here are the steps I’d follow:
1. First, I’d shoot my images and save them in RAW format. This format would enable anyone to make changes to the images later.
2. I’d use Photoshop to modify or correct the color of the images.
3. I’d convert the images into black-and-white versions.
4. I’d save the selected files in the TIFF format. This method will ensure that the images retain their quality and are print-ready.
5. I’d also convert these files into the JPEG format to get good-quality, low-resolution images for the client’s web publishing.
6. The Art Director requires images that they can modify if required. Therefore, I’ll include files in the TIFF and PSD formats. These are open files, and, therefore, anyone can modify them.
I’d send all these saved copies to the magazine for their work.

Which of the following devices are used in networking?A. Routers.
B. Hubs.
C. TCP.
D. Switches.
Answers
Answer:
A, Routers
Explanation:
Routers are used
The devices used in networking are:
A. Routers
D. Switches
Thus, option (A) and (D) are correct.
A. Routers: Routers are network devices that facilitate the transfer of data packets between different networks. They determine the best path for data to reach its destination and enable communication between devices on separate networks.
B. Hubs: Hubs were commonly used in early networking but are now outdated. They are passive devices that broadcast data to all connected devices, leading to inefficient data transmission.
C. TCP: TCP (Transmission Control Protocol) is not a networking device but rather a communication protocol used in the transport layer of the TCP/IP protocol suite. It ensures reliable data delivery by establishing a connection between devices and managing data flow control.
D. Switches: Switches are network devices that connect multiple devices within a local area network (LAN). They forward data packets only to the intended recipient, allowing for efficient data transmission within the same network.
Thus, Routers and Switches are parts.
Thus, option (A) and (D) are correct.

What is an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem?A. Intelligence system.B. Artificial intelligence.C. Neural network.D. Genetic algorithm.
Answers
Explanation: A genetic algorithm is an intelligent system that mimics the evolutionary, survival-of-the fittest process to generate increasingly better solutions to a problem. Genetic algorithms are used to design aircraftparts such as fan blades etc.
Artificial intelligence system exploits the use of computers and technological devices to simulate the human mind's to solve potential problem concerns and make strategic decisions.
Artificial intelligence is essential due to the fact that it provides businesses with virtually unlimited insights into their operations and in some circumstances, Artificial intelligence can carry out tasks better than people, especially when it comes to recurring, technical-detailed activities like reviewing huge quantities of datasets to ensure essential fields are accurately filled in.
However, Neural networks are based on Deep learning techniques, which are a subfield of machine learning. They're designed by the use of the concept of the human brain, and they work by simulating how real neurons communicate with one another.
In the disciplines of Artificial intelligence and machine learning, neural networks mimic the activity of the human brain, enabling computer programs to identify patterns, formulate strategies and tackle basic problems.
Finally, from the scope of Artificial intelligence, Genetic algorithm emulates the principle of Darwinian selection which chooses only the fittest for reproduction. By replicating the evolutionary path of survival-of-the-fittest to accomplish a stated goal, genetic algorithms could solve difficult issues with numerous variables and a huge number of alternative solutions.
Therefore, from the above explanations, we can conclude that an artificial intelligence system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better solutions to a problem is known as a Genetic algorithm.
