what is the first computer?

Answers

Answer 1

Answer:

The first computer was called the "Atanasoff-Berry Computer" (ABC), which was developed by John Atanasoff and Clifford Berry in the late 1930s and early 1940s. The ABC was an electronic computer that used binary digits (bits) to perform calculations, and it was designed to solve systems of linear equations. While the ABC was not a general-purpose computer, it represented a major milestone in the development of electronic computing and laid the groundwork for later computer designs.

Trace coding below

while d > f

d = d + 1

endwhile

output d, e, f

Answers

Based on the code provided, it seems to be a pseudo code or algorithmic representation of a program with a while loop. However, there are a few issues with the syntax and logic of the code. Here's a corrected version with explanations:

php

Copy code

d = 4 // Assigning value 4 to variable d

e = 6 // Assigning value 6 to variable e

f = 7 // Assigning value 7 to variable f

while d > f // While loop condition, loop will run as long as d is greater than f

d = d + 1 // Increment the value of d by 1

e = e - 1 // Decrement the value of e by 1

endwhile

output d, e, f // Output the values of variables d, e, and f

What is the coding?

The corrected code will increment the value of d by 1 and decrement the value of e by 1 repeatedly in the while loop until d is no longer greater than f. After the loop, the final values of d, e, and f will be outputted.

Please note that this is just a pseudo code or algorithmic representation, and it may not be directly translatable into a specific programming language without proper syntax and logical modifications.

Note that the subnet mask fo rt the maximum number of hosts will be 255.255.255.224.

How is this so?

The subnet mask for the maximum number of hosts would be 255.255.255.224 because 29 subnets require 5 bits for subnetting, leaving 3 bits for the host portion of the address (32 - 5 = 27; 32 - 27 = 5; 2^5 = 32; 32 - 2 = 30 usable hosts).

Each subnet can have 30 hosts.

To find the IP address of host 3 on subnet 6, we need to determine the starting address of subnet 6. Since each subnet has 30 hosts, subnet 6 would start at 227.12.1.160. Host 3 on subnet 6 would then have the IP address 227.12.1.162.

Insertion sort in java code. I need java program to output this print out exact, please. The output comparisons: 7 is what I am having issue with it is printing the wrong amount. My comparison that I am getting is output comparison: 4, which is wrong.
When the input is:

6 3 2 1 5 9 8

the output is:

3 2 1 5 9 8

2 3 1 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 8 9

comparisons: 7

Here are the steps that are need in order to accomplish this.
The program has four steps:

1 Read the size of an integer array, followed by the elements of the array (no duplicates).
2 Output the array.
3 Perform an insertion sort on the array.
4 Output the number of comparisons and swaps performed.
main() performs steps 1 and 2.

Implement step 3 based on the insertion sort algorithm in the book. Modify insertionSort() to:

Count the number of comparisons performed.
Count the number of swaps performed.
Output the array during each iteration of the outside loop.
Complete main() to perform step 4, according to the format shown in the example below.

Hints: In order to count comparisons and swaps, modify the while loop in insertionSort(). Use static variables for comparisons and swaps.

The program provides three helper methods:

// Read and return an array of integers.
// The first integer read is number of integers that follow.
int[] readNums()

// Print the numbers in the array, separated by spaces

Assume that you want to collect books from people for your library. When people donate a book check if you already have that book in the library. If more than 2 books of that title already exist say sorry we already have enough of those book. Can you please come back to donate some other book. If there are less than 2 books if that title in the library accept the book and and add it to library.
This is a python question. So copy-paste your answer directly from python. If your answer is wrong, then I am taking it down

If it is correct, you'll get 50 points

Answers

Here's a Python function that implements the logic you described:

```
def add_book_to_library(library, book):
if book in library and library[book] >= 2:
print("Sorry, we already have enough copies of that book. Please donate a different book.")
else:
if book in library:
library[book] += 1
else:
library[book] = 1
print("Thank you for donating a copy of", book)

# Example usage:
library = {'Harry Potter': 2, 'Lord of the Rings': 1}
add_book_to_library(library, 'Harry Potter') # Should print "Sorry, we already have enough copies of that book. Please donate a different book."
add_book_to_library(library, 'To Kill a Mockingbird') # Should print "Thank you for donating a copy of To Kill a Mockingbird"
```

This function takes two arguments: `library` is a dictionary that maps book titles to the number of copies of that book currently in the library, and `book` is the title of the book being donated. If the library already has 2 or more copies of the book, it prints a message asking the donor to donate a different book. Otherwise, it adds the book to the library (if it's not already there) and increments the count of that book in the library by 1.

Discuss the importance of the topic of your choice to a fingerprint case investigation.

Answers

The topic of fingerprint analysis is of critical importance to a fingerprint case investigation due to several key reasons:

Identifying Individuals: Fingerprints are unique to each individual and can serve as a reliable and conclusive means of identification. By analyzing fingerprints found at a crime scene, forensic experts can link them to known individuals, helping to establish their presence or involvement in the crime. This can be crucial in solving cases and bringing perpetrators to justice.

What is the use of fingerprint?

Others are:

Evidence Admissibility: Fingerprint evidence is widely accepted in courts of law as reliable and credible evidence. It has a long-established history of admissibility and has been used successfully in countless criminal cases. Properly collected, preserved, and analyzed fingerprint evidence can greatly strengthen the prosecution's case and contribute to the conviction of the guilty party.

Forensic Expertise: Fingerprint analysis requires specialized training, expertise, and meticulous attention to detail. Forensic fingerprint experts are trained to identify, classify, and compare fingerprints using various methods, such as visual examination, chemical processing, and digital imaging. Their skills and knowledge are crucial in determining the presence of fingerprints, recovering latent prints, and analyzing them to draw conclusions about the individuals involved in a crime.

Lastly, Exclusionary Capability: Fingerprints can also serve as an exclusionary tool in criminal investigations. By eliminating suspects or individuals who do not match the fingerprints found at a crime scene, fingerprint analysis can help narrow down the pool of potential suspects and focus investigative efforts on the most relevant individuals.

In the past 20 years, the United States has carried out a "Color Revolution" all over the world. The "Arab Spring" in 2010, the multi-national riots in the Middle East, the Syrian crisis in 2013, led to the outbreak of the global refugee crisis, the "Ukrainian riots" in 2014, and the civil war broke out in eastern Ukraine. Now, the United States has extended its "black hand" to China.
Only relying on science and technology, finance and capital to plunder wealth can not satisfy Westerners. Therefore, they began to engage in a "Color Revolution", that is, to make profits by subverting the regimes of other countries.
The Soviet Union and the western media spent only money to "subvert" the Eastern European Revolution in 1991. Once the Soviet Union and the western media broke up, they did not spend money to "subvert" the Eastern European Revolution. This wave of operation made the United States earn more, NATO expanded eastward, the Soviet people's wealth of $20 trillion accumulated over 70 years was looted, and a large number of national elites and senior intellectuals such as Soviet scientists, artists and writers fled to western countries.
Since ancient times, the West has a historical tradition of banditry at the expense of others and ourselves. The color revolution has made huge profits and is also the only low-cost subversive means.

# number of elements as input

n = int(input("How many numbers will be added to original list : "))

# iterating till the range

for i in range(0, n):

ele = int(input())

lst.append(ele) # adding the element

n1 = int(input("Enter a number Between 0 and "+str(n)+":")) // enter smaller number elememts

Write a program in QBASIC that asks radius of a circle to calculate its area and circumference. Create a user-defined function to calculate area and sub-program to calculate circumference. [HINTA = T C = 2nr]

Answers

Answer:

Here's a QBASIC program that asks for the radius of a circle, calculates its area using a user-defined function, and calculates its circumference using a sub-program:

```

REM Circle Area and Circumference Calculator

CLS

REM Define user-defined function to calculate area

DEF FNarea(r)

area = 3.14159 * r * r

FNarea = area

END DEF

REM Define sub-program to calculate circumference

SUB CalcCircumference(r)

circumference = 2 * 3.14159 * r

PRINT "Circumference: "; circumference

END SUB

REM Ask for radius input

INPUT "Enter the radius of the circle: ", r

REM Calculate and print area using user-defined function

area = FNarea(r)

PRINT "Area: "; area

REM Calculate and print circumference using sub-program

CALL CalcCircumference(r)

END

```

In this program, the user-defined function `FNarea` calculates the area of the circle using the formula `area = pi * r^2`. The sub-program `CalcCircumference` calculates the circumference of the circle using the formula `circumference = 2 * pi * r`. The `INPUT` statement asks the user to input the radius of the circle. The program then calculates and prints the area and circumference of the circle using the user-defined function and sub-program.

Package Newton’s method for approximating square roots (Case Study: Approximating Square Roots) in a function named newton. This function expects the input number as an argument and returns the estimate of its square root. The program should also include a main function that allows the user to compute the square roots of inputs from the user and python's estimate of its square roots until the enter/return key is pressed.

An example of the program input and output is shown below:

Enter a positive number or enter/return to quit: 2
The program's estimate is 1.4142135623746899
Python's estimate is 1.4142135623730951
Enter a positive number or enter/return to quit: 4
The program's estimate is 2.0000000929222947
Python's estimate is 2.0
Enter a positive number or enter/return to quit: 9
The program's estimate is 3.000000001396984
Python's estimate is 3.0
Enter a positive number or enter

Declare a Boolean variable named goodPassword. Use goodPassword to output "Valid" if passwordStr contains at least 4 letters and passwordStr's length is less than or equal to 7, and "Invalid" otherwise.

Ex: If the input is xmz97H2, then the output is:

Valid

Ex: If the input is 4rY2D0QR, then the output is:

Invalid

Note: isalpha() returns true if a character is alphabetic, and false otherwise. Ex: isalpha('a') returns true. isalpha('8') returns false.

}

#include
using namespace std;

int main() {
string passwordStr;
bool goodPassword;
