Answer:
import re
def country_capita():
#opens file
file=open("inputfile.txt", "r")
dictionary=dict()
#reads line by line
for line in file.readlines():
# substitutes for multiple space a single space
line = re.sub(r"[\s]{2, }", ' ', line)
list=[]
#splits line on space
list=line.split(" ")
#put into dictionary
dictionary[list[1]]=list[2]
# get input
while True:
choice=input("Enter the country name or quit to exit: ")
if choice=="quit":
break
elif choice in dictionary.keys():
print(dictionary[choice])
else:
print("Invalid Country")
country_capita()
Explanation:
Using python to code this program. First we, (line 1) import the re module which offers us a set of functions that allows us to search a string for a match. ((line 2) Next we define a function country_capita() that will open rawdata_2004.txt, read the information within line by line and create a dictionary list. The we create a while loop with conditional statements that prompt the user to enter country names, print the corresponding values and stops when the user enters quit.

Answer:
d) Online, real-time systems.
Explanation:
The options are:
a) Batch processing systems.
b) Personal computer systems.
c) Data compression systems.
d) Online, real-time systems.
And the correct option is D. Online, a real-time system. And this is because it is this which is characterized by the data which is assembled from more than one location as it is online, and various clients from various locations enter the data, and it's updated immediately, as it is a real-time system, which is updated in real-time. And hence D. is the correct option. The data compression system takes the data from one location at a time. The batch processing system is made up of different programs for input, output, and process. and hence is different from real-time, which requires continual all the three. And a PC is not made to a specific function, and it does different activities. Hence, its also not the right option here.

Answer:
the 256 color icon would be greater in file size.
Explanation:
regardless of how many pixels are in the image, file A has 256 colors meaning the computer has to individually load each one of those colors. it'll probably use a lot of ink if you decide to print it, too.
