Using a Counter-Controlled whileLoop Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions Ensure the file named Multiply.java is open. Write a counter-controlled while loop that uses the loop control variable to take on the values 0 through 10. Remember to initialize the loop control variable before the program enters the loop. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. Execute the program by clicking Run. Record the output of this program.

A program stores the prime numbersin a file named PrimeNumbers.dat. Write a program that finds the numberof prime numbers that are less than or equal to 12, 120, 1,200, 12,000,100,000, 1,200,000, 12,000,000, 120,000,000, 1,200,000,000, and12,000,000,000. Your program should read the data from PrimeNumbers.dat.
Create a list of 5 words, phrases and company names commonly found in phishing messages. Assign a point value to each based on your estimate of its likelihood to be in a phishing message (e.g., one point if it's something likely, two points if modereratly, or three points if highly likely). Write an application that scans a file of text for these terms and phrases. For each occurance of a keyword or phrase within the text file, add the assigned point value to the total points for the number of occurences and the point total. Show the point total for the entire message. (Write the program in Java)

The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.
