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.

Using a for Loop Summary In this lab the completed program should print the numbers O through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a for loop instead of a counter- controlled while loop. Instructions 1. Write a for loop that uses the loop control variable to take on the values O through 10. 2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. 3. Execute the program by clicking the Run button at the bottom of the screen. Is the output the same?

C++ Visual 2019 A file called num.txt. write a C++ program that opens a file, reads all the numbers from the file and calculates the following: The number of numbers in the file The sum of all the numbers in the file (a running total) The average of all the numbers in the file The program should display the number of numbers found in the file, the sum of the numbers and the average of the numbers. These are the numbers in the num.txt file :...

C++arrays, c-strings, functions with arrays as parameters 1. Create a file that contains 20 integers or download the attached file twenty_integers.txt Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the fileinto the array.6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array.Return the maximum value from the function (the function will be of type int).7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages.Ensure the output is readable.

Can this be done in Java and not C++

C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called "numbers.txt" for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.

C lanaguge Managing Student Information! C LANGUAGE We're going to build a student information management system. The user should be shown a menu with four options: display student initials, display student GPAs, add students, or exit the program. If the user chooses to exit, the program should end. Otherwise, if the user chooses to display the student initials, the contents of the students.txt file should be read, and just the student number and initials should be displayed to the user in a tabular format. If the user chooses to display the student GPAs, the contents of the students.txt file should be read, and just the student number and GPAs should be displayed to the user in a tabular format. If the user chooses to add students, they should be prompted for the number of studnets they’d like to add. They should then be prompted that many times for a studnet number, a GPA, a first initial, and a last initial. Each of the new items should be saved to the students.txt file....

Data File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the...

Lab Goal : This lab was designed to teach you how to use a while loop. Lab Description (JAVA PROGRAMMING): Remove all occurrences of the removal string from the original string. Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist. Sample Data : xR-MxR-MHelloxR-M R-M sxsssxssxsxssexssxsesss xs fuxqwexqwertyxqwexqwe Sample Output : xR-MxR-MHelloxR-M - String to remove R-M Hello sxsssxssxsxssexssxsesss - String to remove xs sesss fuxqwexqwertyxqwexqwertyrtyxqwertyrtyn - String to remove qwerty fun dogdogcatddodogdogdoggog - String to remove dog catgog algorithm help use indexOf to look for more removals while you have more removals { take out the current removal using substring use indexOf to look for more removals } I need help with assignment: "String Cleaner" StringRemover.js: //(c) A+...
