Write a program that asks the user for the name of a file. The program should display only the first five lines of the file's contenents if the file contains less than five lines, it should display the files's entire contenents
To write a program that asks the user for the name of a file, we will use the readline() method of our file object, and using a for loop, we'll repeat the readline() five times.
The structure of the program and it's programming:
We will use readline() method of our file object( here it has been taken as file_obj).
Using a for loop we'll repeat the readline() five times.
If the file has less than five lines and we try to keep reading after the read position has gotten to the last character in the file, the readline() function will just return the empty string " ".
So nothing will be displayed. We need set end=' ' in our print() function to ensure that we don't get a bunch of extra new lines.
Don't forget to close the file after you're done with it.
# Getting file name from the user filename = input('Enter the filename :')
# Opening the file in read mode file_obj = open(filename, 'r');
# Reading and displaying the file's first five lines for i in range(5): print(file_obj.readline(), end = '')
# Reads a single line at a time and displays it # Closing the file file_obj.close()

Which two features are most important for Virtual Reality to provide a smooth and enjoyable experience for the user?
Immersion and Interaction are the two most important features of virtual reality.
What is Immersion?
Immersion, also known as presence, refers to the degree of reality in which the viewer exists as the protagonist in the virtual environment. By wearing interactive devices such as helmet-mounted displays and data gloves, viewers can immerse themselves in a virtual environment and become a part of it.
What is Interaction?
Interaction refers to the user's ability to manipulate objects in the simulated environment as well as the natural degree of feedback from the real world. Human-computer interaction in VR technology is similar to natural interaction. There are two kinds of interactions: three-degree-of-freedom (3DoF) interactions and six-degree-of-freedom (6DoF) interactions.
What is Virtual reality (VR)?
Virtual reality (VR) is a simulated experience that uses pose tracking and 3D near-eye displays to immerse the user in a virtual world. A computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person wearing special electronic equipment, such as a helmet with a screen inside or gloves with sensors

Below you can see stringSize, which is implemented in Java
Answer:
(a): Yes, it is logically correct as the code does a loop through the all characters of the string and outputs the total amount of them within the string.
(b): It is poorly designed because it is not the most efficient way to get the size of the string. There is a much better way in obtaining it through s.length() and it also accounts for spaces as characters as well.
Explanation:
Hello! Let's help you with your question here!
Now, it is split up into two parts so I will explain them both as such.
Part A:For this part of the question. Yes, it would be logically correct. When the size is returned, it will return the number of characters in s. Let's break down the code step by step:
Code Rundown:int size = 0; (Initializing a size variable of type int and setting it to 0)for (int i = 0; i < s.length(); i++): We create what is known as an index i and have it loop until it reaches the length of the string (This is where we loop through the characters).size++; (For every loop, it'll just add 1 to size, essentially making it a counter).return size; (This returns the number within size after the loop is finished.)As you can see from the rundown, it initializes a counter and loops through each character of the string and increases the counter as it goes. So for this part, it is logically correct as it does give us the total amount of characters within a string which is considered the string size.
Part B:It is poorly designed under two reasons, one is more important than the other as the second one isn't really a requirement, it's just quality of life.
Reason 1 (The Important One):
The main reason why this is poorly designed is that it is not optimized. What it does here is going through the entire string and adds 1 to the counter every time there is a character. However, s.length() achieves the same thing. Instead of creating a counter and having it loop through the entire string and adding 1 to the counter for every character and then returning the counter. s.length() is a method that returns the length of a specified string. In this case, it returns the size of the string. To put it simply, the code in the example can be simplified to just:
private static int stringSize(String s) {
return s.length();
}
This would still give us the same result as the example without having to go through a loop. In programming and algorithms, we learn about time complexity. To put it simply, it is the time it takes for the program to complete. The faster it does without any errors, the more efficient and optimal it becomes. For the code example above, we have time complexity O(n). What this means is that the program needs to run through a loop (multiple checks) before finishing the code, this is the second fastest time. However, with the code I showed you above, it has a time complexity of O(1). For this code, it doesn't need to run any checks, it can just finish the code immediately. Therefore, the code in the example is not efficient.
Reason 2 (Quality of Life One):While the code does work well and does give you an accurate total size of the string every time, it however accounts for spaces as well. If you were to have a space in your string, it would bump the counter up as in Java, as spaces are considered a character because of this you won't get an accurate string size count if you want letters and symbols only. A way to improve it is to create a check within the loop that tells us if the character we are looking at, in the index, is a space or not. If it is a space, we subtract the size counter by 1 and move on. So the modified code would look like this:
public static int stringSize(String s) {
int size = 0;
for (int i = 0; i < s.length(); i++) {
size++;
char c = s.charAt(i);
if (c == ' ') {
size--;
}
}
return size;
}
Explanation:In the code, I am still adding 1 to the size counter still. However, in the bold. I create a variable c of type char and take the character of the string where the index is currently and use an if statement to determine if it is a space or not. If it is not, then the code repeats until the loop is done and then returns the size of the string. However, if it is a space, it'll subtract 1 from the size counter and will loop through the entire string doing this check and then returns the size of the string when it is done.

Define a method named minNumber that takes four integer parameters and returns an integer representing the minimum of the four integers.
