Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Total numbers of words is 20
Figure 1 A sample input file
55.000 % of numbers are palindrome
Figure 2 A sample output using sample input in figurel
Each line in the input file contains one word as shown in Figure 1. Your program should read each
word and identify if it is a palindrome or not. A palindrome is a text that reads the same forward
(right to left) and backward (left to right).
Your program must define and use the following functions:
• isPalindrome(): receives a string and returns True if the string is palindrome, otherwise it
returns False. For example, if the string is “Python" the function will return False. If the string is
"Hannah" it returns True.
• displayHeader(): displays the header (the first three lines) shown in Figure 2
• main(): opens the input file "strings.txt" for reading, reads data from it, and calls the various
functions, and finally prints the results on screen formatted as shown in Figure 2. If the input
file is not found, an exception is raised and an error message must be displayed.

Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.

Write a program that asks the user for a file name and a string to search for. The program should search the file for every occurrence of a specified string. When the string is found, the line that contains it should be displayed. After all the occurrences have been located, the program should report the number of times the string appeared in the file.
