Dennis_Churaev [7]

Answer:

1940 – 1956: First Generation

1956 – 1963: Second Generation

1964 – 1971: Third Generation

1972 – 2010: Fourth Generation

2010- : (Present )Fifth Generation

Explanation:

First Generation Computers (1940-1956):In this Generation the main component of computers were Vacuum Tubes.
Second Generation Computers (1956-1963):In this generation the main component of computers were Transistors.
Third Generation Computers (1964-1971):In this generation the main component of computers were Integrated Circuits.
Fourth Generation Computers (1972-2010):In this generation the main component of computers were Microprocessor
Fifth Generation (2010-Present):In this generation the main component of computers is Artificial Intelligence

Consider the following code segment, where num is a properly declared and initialized integer variable. The following code segme

seropon [69]

Answer:

10 or 22 or 15 or 40

Explanation:

In the second for loop[for (int k = 1; k < arr[0].length; k++)], k starts from 1 instead of zero. That means that it doesn't read the first value of every row when finding num.

So if num was any of the above values, the program wouldn't work. I had the same question, and the answer for mine was 15.

Write a program that will take a file named Celsius.dat that contains a list of temperatures in Celsius (one per line), and will

dedylja [7]

Answer:

celciusFile=open("celcius.dat","r")

fahrenheitFile=open("fahrenheit.dat","w")

# Iterate over each line in the file

for line in celciusFile.readlines():

# Calculate the fahrenheit

fahrenheit = 9.0 / 5.0 * float(line) + 32

#write the Fahrenheit values to the Fahrenheit file

fahrenheitFile.write("%.1f\n" % fahrenheit)

# Release used resources

celciusFile.close()

fahrenheitFile.close()

Explanation:

celciusFile=open("celcius.dat","r")

fahrenheitFile=open("fahrenheit.dat","w")

open the Celsius file in the read mode and assign it to a variable.

open the Fahrenheit file in the write mode and assign it to a variable.

read mode means you can only use/read the content in the file but cannot alter it.

write mode means you can write new data to the file.

# Iterate over each line in the file

for line in celciusFile.readlines():

The values contained in the Celsius file are collected.

# Calculate the fahrenheit

fahrenheit = 9.0 / 5.0 * float(line) + 32

The values are then converted to Fahrenheit.

#write the Fahrenheit values to the Fahrenheit file

fahrenheitFile.write("%.1f\n" % fahrenheit)

The Fahrenheit values are written to the Fahrenheit file

%.1f is used to specify the number of digits after decimal. and \n adds a new line.

# Release used resources

celciusFile.close()

fahrenheitFile.close()

All files are closed
