Write a program that prompts the user for an input file name, reads all words from the input file, and writes the words to the output file sentences.txt. Start a new line whenever a word ends in a period, question mark, or exclamation mark. Also do this the period, question mark, or exclamation mark is followed by a quotation mark. Otherwise, separate words with spaces.

Write a C++ program using classes that readslines from a file until the end of file. The program should prompt the user for the file name to read from. The program should open the file for reading, and if the filecannot be opened, print the message “File couldn’t be opened”, followed by a space and the filename, and exit. The program should keep track of the number of lines, the number of non-blank lines, the number of words, and the number of integers read from the file.

Write a program that reads student's IDs and exam scores (type int) for a particular exam in a course from each line of an input file (the input file is included). You need to compute the average of these scores and assign grades to each student according to the following regulation: 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, the grade will be outstanding. If a student's score is more than 10 points below the average, the grade will be unsatisfactory. The output of your program should consist of a three-column table that shows each ID, score, and corresponding grade. A sample output is shown below. ID SOLS SENTO 0 1 2 3 4 8 9 Score 75 99 66 43 87 65 82 91 84 76 Grade Satisfactory Outstanding Unsatisfactory Unsatisfactory Outstanding Unsatisfactory Satisfactory Outstanding Satisfactory Satisfactory Write necessary functions and put them in a module to process this…
2. Write a program, called RemoveText, that removes all the occurrences of a specified string from a text file. The specified string and file are both input as command line parameters. For example, invoking java RemoveText John example.txt removes string John from the specified file "example.txt". The program shall display "Plz use this format: java Task2T8 String filename" if the parameters are not properly provided and then terminate the program, and display "The specified file is not exist!" if the specified file is not existed and then terminate. 3. Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The formula for the calculation is as follows: futureValue = investmentAmount * (1 + monthlyInterestRate)ears" 12 Use text fields for interest rate, investment amount, and years,

A program that processes an input ﬁle and produces an output ﬁle is called a ﬁlter. Write a program that asks the user for two ﬁle names. The ﬁrst ﬁle will be opened for input, and the second ﬁle will be opened for output. (It will be assumed that the ﬁrst ﬁle contains sentences that end with a period.) The program will read the contents of the ﬁrst ﬁle and change all the letters other than the ﬁrst letter of sentences to lowercase. First letter of sentences should be made uppercase. The revised contents should be stored in the second ﬁle.
Write a program that reads in from a file a starting month name, an ending month name, and then the monthly rainfall for each month during that period. As it does this, it should sum the rainfall amounts and then report the total rainfall and average rainfall for the period. For example, the output might look like this: During the months of March-June, the total rainfall was 7.32 inches and the average monthly rainfall was 1.83 inches. Data for the program can be found in the rainfall.txt file located in the Chapter 5 º programs folder on the book's companion website. Hint: After reading in the month names, you will need to read in rain amounts until the EOF is reached and count how many pieces of rain data you read in.
Create a program that reads in a word from the user and counts the number of occurrences of that word in a file called words.txt. -- words.txt This is a file that contains many words. Yes it does have so many words. Many, many words. Well, maybe it is not that many after all. So, just how many is MANY?
Problem A straight line can be defined by a pair of points p1(x1, yı) and p2(x2, y2). The slope m of a line is defined as follow: У2 — У1 m = X2 - X1 Your program reads the points from a text file called 'points.txt’ which contains the coordinates of unknown number of pairs of points as shown in Figure 1. Each line contains four values x1, y1, x2, y2, where x1, yl are the coordinates of the first point and x2, y2 are the coordinates of the second point. 10 -2 7.5 -3.2 4 15.5 -4.6 21 -2 Зр 12.5 6. 2 5 -3 -6 10 3 10 15 Figure 1.
