- This assignment is specifically designed to help you practice writing short Java programs and executing them at the command line. You are given a sample program and a description of what it is supposed to do. But there are errors, so you need to fix the errors and run the program. Start by launching a text editor, save the file as "Payroll.java" into your IST140 directory. Here is the code for your program (don't try to copy and paste, it will include unprintable characters and you will have errors when you compile): public class Payroll{ public static void main(String[] args) { double hrlyWage, hrsWorked, salary; hrlyWage 15.5; HrsWorked = 20; } } //Bug here salary hrlyWage + hrsWorked; // Bug here System.out.print("Salary: $" + salary); Save the file when you are done adding the code from above. Then, navigate back to the command window. Now if you type 'dir' on a windows machine (or Is on a mac), you should see the new file. Compile the new program using javac Payroll.java After it…In Java Only: My program is not working correctly, The history teacher at your school needs help grading a true/false test.The student's IDs and test answers are stored ina file, The first entry in the file contains the answers to the test in the following form: TFFTFFTTTTFFTFTFTFTT Every other entry in the file is the student;s ID, followed by a blank, followed by the student;s response. For example, the entry: ABC54301 TFTFTFTT TFTFTFFTTFT indicstes that the student;s ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is false, and so on. This student did not answer question 9. he exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded 2 points, each wrong answer gets -1 point, and no answer gets 0 points. Write a program that processes the test data. The output should be the student's ID, followed by the student's answers, followed by the test score, and then followed by the test grade. Here is my code, I keep…Need help with this python programming question.
- You are given a file, input.txt, that contains some even number of lines. Each line contains two values: a number and a string. For this task, you need to write a Java code to calculate the sum of the numbers in two consecutive lines of input.txt and write the sum in another file, output.txt. Check the following example for details: 123 100 50 50 45 55 input.txt output.txt Line 1: 223 Line 2: 100 Line 3: 100 Here, the first output is 223 which is equal to 123 + 100. The second output is 100 which is equal to 50+ 50 and so on. The three dots at the end of input.txt means that there are many more lines in the file.Java. Write an application that accepts a word from a user and converts it to Pig Latin. If a word starts with a consonant, the Pig Latin version removes all consonants from the beginning of the word and places them at the end, followed by ay. For example, cricket becomes icketcray. If a word starts with a vowel, the Pig Latin version is the original word with ay added to the end. For example, apple becomes appleay. If y is the first letter in a word, it is treated as a consonant; otherwise, it is treated as a vowel. For example, young becomes oungyay, but system becomes ystemsay. For this program, assume that the user will enter only a single word consisting of all lowercase letters.Write a program that reads a file one character at a time and prints out how many characters are uppercase letters, lowercase letters, digits, white space, and something else.

- Write a program for the following problem. You're given a file that contains a collection of IDs and scores (type int) for an exam in your computer course. You're to compute the average of these scores and assign grades to each student according to the following rule: If a student's score is within 10 points (above or below) of the average, assign a grade of satisfactory. If a student's score is more than 10 points above average, assign a grade of outstanding. If a student's score is more than 10 points below average, assign a grade of unsatisfactory. The output from your program should consist of a labeled three-column list that shows each ID, score, and corresponding grade. As part of the solution, your program should include functions that correspond to the function prototypes that follow. 7/ reads exam scores into array Scores void readStuData (ifstream &rss, int scores[], // IN: data file // OUT: the scores Oum, the TDsI have this homework where I have to search a word in a file and count how many words in and how long takes to find it.

In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255. Tip 3: Instructions and sample program for working with time. C language plz with explanation of codes. thanks
