Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called "story.txt"
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used – times.
b was used – times.
c was used – times.... .and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array]
Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]:

Ql: Write a program to calculate the average of four integer score, and find the grade for 7
students.
The program should do the following:
1. Read the first, second name and the four score of the 7 student from the file (E:\lexam.txt),
2. Calculate the average and find the grade of the average by using the if and if else.
3. Save the first, second name, average and the grade for each student in file
(E:\\grade.txt). (10 columns for the first and second name. 4 columns, precision 2,
for the average and grade)
Computer Science
C++
Create a text file "input.txt" with a certain amount of integers (you decide how many).
Write a program that reads these numbers from the file, adds them, and when you have reached the end of the file, calculates the average of these numbers. Print a message and the average to the console.
Code this program twice, demonstrating the two methods to detect the end of the file,
part A: reading a value from Instream and storing it (boolean expression) in the while loop
part B: using the eof() member function

The program should pick a word (which is either coded directly into the program or read from a text file) and display the following: Guess the word: XXXXXX Each X represents a letter. The user tries to guess the letters in the word. The appropriate response yes or no should be displayed after each guess. After each incorrect guess, display the diagram with another body part filled. After seven incorrect guesses, the user should be hanged. The display should look as follows: O /|\ | / \ After each guess, display all user guesses. If the user guesses the word correctly, display: " Congratulations!!! You guessed my word.

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students.

When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful.
