The program is an illustration of loops.
Loops are used to carry out repetition operations; examples are the for-loop and the while-loop.
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
public class Main {
public static void main(String args[]) {
//This creates a Scanner object
Scanner input = new Scanner(System.in);
//This prompts user for input
System.out.print("Input a word: ");
//This gets input from the user
String userinput = input.nextLine();
//The following iterates through every other character of userinput
for(int i =0;i<userinput.length();i+=2) {
//This prints every other characters
System.out.print(userinput.charAt(i));
}
}
}
The above program is implemented using a for loop

[Files, for loops, exceptions; 20pt] Using a for loop, write a function called countWord(). It takes 2 parameters: The name of a text file (e.g. gettysburg.txt that is included with this test) and a word to be searched within that file. Your code should return the number of times the given word appears in the file. Capitalization should not matter. Make certain to handle file exceptions gracefully.
def countWord(name, word):
try:
f = open(name, "r")
lst = ([])
w = ""
for x in f.readlines():
w += x.lower()
lst = w.split()
f.close()
return lst.count(word)
except FileNotFoundError:
print("Please create a file or use the name of an existing text file.")
print("Your word appears", countWord("gettysburg.txt", "random"), "time(s)")
The text file I used for testing looks like:

A friend a just opened his own barber shop and has asked you to develop a program to track the type of service the customer is receiving and the cost for the service and also include any tips the customer may give to the barber.

Name your variables Declare your variables
Answer:
class Barber(object):
barber_shop = "Big AI's barber shop"
def __init__(self, customer_name, type_of_service=[], tip=0):
self.cust_name = customer_name
self.tos = type_of_service
self.tip = tip
def service_type(self, *args):
for i in args:
self.tos.append(i)
def total(self):
services = {'trimming':10, 'hair_cut':20, 'shaving':15, 'washing':5, 'dyeing':5}
contain = ''
total = 0
for service in self.tos:
if service in services.keys():
total += services[service]

f'total: ${total}', '\n',f'Tip: ${self.tip}')
mycust = Barber('John',['washing'],6 )
mycust.service_type('shaving', 'dyeing')
mycust.total()
Explanation:
The Barber class is a blueprint used to create an object instance of customers that visits the barber-shop. It has two methods 'service_type' and 'total' which are just defined functions of the class that appends services to the type of service variable and total that prints the total cost of services on the screen.

CALCULATE THE PERCENTAGE OF FAT CALORIES TO TOTAL CALORIES. I got no idea how to do this in excel ;-;
Answer:
As you have the Fat Cal. in column C and the total calories in Column B, what you have to do is to divide column C by Column B.
For instance, in column E2, put the formula: =C2/B2.
Then drag the formula down so that the other formulas will be;
E3; =C3/B3
E4; =C4/B4
E5: C5/B5
E6: C6/B6
Then after that you go to the Home tab, then to the Number style section and format E2 to E5 to be percentages.

[Exceptions, Function calling another function] Write a function ticker() that first runs (calls) read_ticker() and then stores the returned dictionary. It then runs an interactive loop with the user in which the user is prompted for a company name. If the company name (key) is in the dictionary, then its ticker form and the IPO year is printed. Otherwise a warning is printed that the company name is not in the list. If the user just hits return without entering a name, the loop stops.
this is the function that needs to be called:
def read_ticker():
d = {'1347 Capital Corp.': ('TFSCW', '2014'), '1347 Property Insurance Holdings, Inc.': ('PIH', '2014'), '1-800 FLOWERS.COM, Inc.': ('FLWS', '1999')}

What is cursor?
A cursor is an indicator used in computer user interfaces to show the current position for user interaction on a computer monitor or other display device that responds to input from a text input or pointing device. Because of its usage resemblance to a pointing stick, the mouse cursor is also known as a pointer. Cursor is a Latin word that means "runner." The transparent slide engraved with a hairline that is used to mark a point on a slide rule is known as a cursor. By example, the word was later transferred to computers. On November 14, 1963, while attending a computer graphics conference in Reno, Nevada, Douglas Engelbart of the Augmentation Research Center (ARC) expressed his desire to pursue his goal of developing both software and hardware computer technology to "augment" human intelligence by pondering how and where to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data.
