Computers and Technology

Bond [772]2 years ago

Answer:

<em>A computer monitor</em> is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.

<em>A printer</em> is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

<em>Speakers</em> receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

Write a program that accepts a positive integer N as command-line argument, and outputs True if N is the square of some integer,
Ann [662]

Answer:

In Python:

N = int(input("Positive integer: "))

if N > 0:

   flag = False

   for i in range(1,N+1):

       if i * i == N:

           flag = True

           break

   print(str(flag))

else:

   print("Positive integer only")

   

Explanation:

N = int(input("Positive integer: "))

If the number is positive

if N > 0:

This initializes a boolean variable to false

   flag = False

This iterates from 1 to the input integer

   for i in range(1,N+1):

This checks if th number is a square of some integer

       if i * i == N:

If yes, flag is set to true

           flag = True

The loop is exited

           break

This prints either true or false, depending on the result of the loop

   print(str(flag))

If otherwise, that the number is not positive

<em>else:</em>

<em>    print("Positive integer only")</em>

<h3>What does a file structure field mean?</h3>

A record is an entire set of fields, a field is a single piece of information, and a file is a collection of records. An analogy between a file and a phone book is a phone book. There is a list of records in it, and each record has three fields: a name, an address, and a phone number.
