Programming Challenge #7: Word Frequency Count: Write a program that allows the user to specify a text file, opens the file, and prints a two-column table consisting of all the words in the file together with the number of times that each word appears. Words are space-delimited and case-sensitive. The table should list the words in alphabetical order.

A for construct is a loop construct that processes a specified list of objects. As a result,it is executed as long as there are remaining objects to process. True or False?

C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.  Attached is the first lines of the .txt file

Cassignm222 Assignment 2 features designing a program using pseudocode and then completing the program in Python using a list. M4Lab2 asks you to write a Drawing app in Python and Pygame using a list for the colors. Each lab asks you to write pseudocode that plans the program's logic before you write the program in Python and to turn in three things: 1) the  pseudocode, 2) a screenshot of the output, and 3) the Python program. # Step 1: Define a colors list to describe 3 colors.# Hint, use their RGB number values Step 2: define a radius variable for your pen at 5, 10 or 15# Test them to see which radius you prefer and use it # Step 3: write the elif for pressing button 2, similar to button 1        # Step 4: write the statement for button 2's color # Step 5: write the else statement for button 3  # Step 6: choose a color from the list??

5. Charge Account Validation If you have downloaded the source code from the Computer Science Portal you will find a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com- pany's valid charge account numbers. Each account number is a seven-digit number, such as 5658845. Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid. If the number is not in the list, the program should display a message indicating the number is invalid. (You can access the

The intNums array is declared as follows: Dim intNums() As Integer = {10, 5, 7, 2}. Which of the following blocks of code correctly calculates the average value stored in the array? The intTotal, intSub, and dblAvg variables contain the number 0 before the loop is processed. a. Do While intSub < 4 intNums(intSub) = intTotal + intTotal intSub += 1 Loop dblAvg = intTotal / intSub b. Do While intSub < 4 intTotal += intNums(intSub) intSub = intSub + 1 Loop dblAvg = intTotal / intSub c. Do While intSub < 4 intTotal += intNums(intSub) intSub += 1 Loop dblAvg = intTotal / intSub – 1 d. Do While intSub < 4 intTotal = intTotal + intNums(intSub) intSub = intSub + 1 Loop dblAvg = intTotal / (intSub – 1)
