Answer:
a starting point might be after you get this working, you can allow them to enter more words and iterate your search,
for each argument (not counting the first one that is the file name)
search for the word, show the lines...
and more files too, for that matter, for each file, for all the words... (at this point you MUST put flags on what each thing is, up to now, you can use the order of args)
just note that arg[] are c-strings. you can assign a string a c-string, so promotion lets you do things more normally, or you can process it as-is depending on what you use it for (see how I just used it in the file name but moved it to a string in the target?). I plan to use target a lot, but the file name only in one statement ever, no need to upcast it.
Explanation:
int main(int argc, char* argv[])
{
if(argc < 3) //if the user did not provide enough command line inputs.
//you can, and should probably, do more exhaustive input validation and maybe have them
//do flags as well rather than rely on the order of the arguments to be correct.
{
cout << "usage: mygrep filename word"
return 1;
}
ifstream infile(argv[1]); //attempt to open the first target as the file
string target = argv[2]; //assign target from the second argument
...
Use the class below to determine IF there is an error or if some part of the code is missing.
public class acceptInput {
public static void main (String[ ] args) {
Scanner scan = new Scanner (System.in);
System.out.println("How old are you? ");
int age = scan.nextInt();
System.out.println("Wow you are " + age + " years old. ");
}
}
- Scanner object has been declared incorrectly
- .nextInteger() should be used to accept an integer from the user.
- Age variable is not correctly printed in the sentence
- import java.util.Scanner; is missing
- Program runs as expected
Based on the given class below:
public class acceptInput {
public static void main (String[ ] args) {
Scanner scan = new Scanner (System.in);
System.out.println("How old are you? ");
int age = scan.nextInt();
System.out.println("Wow you are " + age + " years old. ");
}
}
The error that can be seen here is that the Scanner object has not been created
What is Debugging?This refers to the term that is used to describe finding errors in a given program or system that prevents a code from properly executing and involves certain steps and processes.
Hence, it can be seen that the error in the code above is that there is the use of the Scanner object, but it is yet to be created which would return errors when the program is being run.

Beth wants to start a multimedia business in 3D modeling and sound integration and editing. She should invest in Adobe Substance 3D Modeler for 3D modeling and Adobe Audition for sound editing.
What is 3D modeling?3D modeling is a method in 3D computer graphics that involves manipulating edges, vertices, and polygons in a simulated 3D environment to create a mathematical coordinate-based depiction of any surface of an object in three dimensions using specialist software.
3D modeling may be applied almost anywhere. We know it's popular in film, video games, and animation, but that's not all. From architecture to mechanical engineering to the medical business, all of these demanding industries are finally realizing and capitalizing on the full potential of 3D modeling. 3D modeling may be beneficial in a variety of ways.
3D modeling may be classified into the following categories:
Solid modeling is used to create three-dimensional forms. The forms may differ, yet they function as building blocks when combined. Depending on the input, some of these blocks add material while others delete.
When the surface is complicated and curved, wireframe modeling might be useful. You'll eventually discover that the fundamental building blocks of solid modeling are too obtuse for some applications, while wireframe modeling gives the refinement for more complicated designs.
The next level of complexity is surface modeling. Smooth surfaces and flawless integration are required for highly professional applications, which may be handled by more complicated programs that need more labor and computational capacity.

Determine if the statement is true or false. Asymmetrical design can be visually balanced from left to right.
True or false
Answer:
true false asan pala tanong dyan?
It is false that the asymmetrical design can be visually balanced from left to right.
What is asymmetrical design?Asymmetrical balance is the technique of achieving a sense of balance by using different visual elements of unequal weight on both sides of a composition.
If you understand that symmetrical means that both sides of something are identical, it should be simple to understand that asymmetrical means that the two sides are different in some way.
Asymmetrical objects are irregular and crooked, and do not perfectly match up when folded in half.
Asymmetry is the lack of symmetry or equality between your design's halves. While both halves of a symmetrical design are the same (or similar), both halves of an asymmetrical design are distinct.
Thus, the given statement is false.

which common design feature among instant messaging clients make them less secure than other means of communicating over the internet?
Peer-to-peer networking is the common design feature among instant messaging clients make them less secure than other means of communicating over the internet.
A straightforward computer network is a peer-to-peer network. It was created for the first time in the late 1970s. Within this network, each computer serves as a node for file sharing. There is no central server in the network because each node acts as a server in this case. This makes a tremendous amount of data sharing possible.
Each node receives an equal share of the tasks. Each linked node in the network has an equal share of work to do. Each node must stop functioning for the network to cease to exist. This is so that each node may function independently.
These networks often have less than 12 nodes, which is not a very large number. Although each machine in the network stores its own data, the entire group has access to it.
Peer-to-peer networks, in contrast to client-server networks, both use and provide resources. If the quantity of nodes rises, more resources are needed. Software specifically for this is needed. It enables network-wide resource sharing.
The nodes serve as both clients and servers, therefore an assault is always a possibility. Peer-to-peer networks are supported by almost all OS today.

Hello Can someone help me with this problem?
Bob and Alice want to send each other secret messages that no one else will have access to. They have decided that they will use a locked box to hold the secret messages, and they will drop the box off in each other’s mailboxes. The problem is that if they use a combination lock, they will have to send the combination to the box and someone might intercept it. Here are the materials they have access to:
A box that can be locked with a combination lock
Two combination locks (the kinds that click shut that you might use on a school locker)
Paper
Pencil
Describe a protocol Bob and Alice can set up to deliver these messages securely.
Explanation:
Bob and Alice could first send each other their open locks. Then, e.g., Alice can send a message to Bob and lock her box with Bob's lock, and vice-versa.
A more real-world approach to this problem is that they use a form of Diffie-Hellman approach to exchange a combination for the lock.
Diffie-Hellman is an algorithm where you can exchange secrets even if you know someone is intercepting each and every message you exchange. It's a bit mathematical, but still very cool.

How many possible hosts can each subnet support?
What is subnets?
A subnetwork, also known as a subnet, is a logical division of an IP network. Subnetting is the practise of dividing a network in to the two or more networks. Computers on the same subnet are addressed in their IP addresses with the same most-significant bit-group. As a result, an IP address is logically divided up into two fields: the network number or routing prefix and the rest field as well as host identifier. The rest field identifies a particular host or network interface.
After subnetting, we have 16+6 = 22 network and 16-6=10 host bits.
No. of unused subnets = 2^6-50 = 14 subnets
No. of hosts. per each subnet =2^10-2 = 1022 hosts.

The concept of abstraction and abstract data types on computer programming is given below.
The use of abstraction to manage complexity is crucial. When anything is regarded abstractly, just the salient characteristics are highlighted. It is not necessary to recall or even notice the information that is left out.
What is abstraction?An abstraction of a data structure that merely provides the interface to which the data structure must conform is referred to as an abstract data type. No precise information about how something should be implemented or in what programming language is provided by the interface.
An object's behavior can be described by a set of values and a set of actions, and this behavior is known as an abstract data type (ADT). The definition of ADT merely specifies the actions that must be taken, not how they must be carried out.
Therefore, List data structures, stack data structures, and queue data structures are examples of abstract data types in data structures. The abstract data type defines a number of legitimate operations that can be performed on a specific data structure.
