If not, print an error message and exit the program.2. Write C code which will read a line of characters (terminated by a \n)from input_file into a character array called buffer. NULL terminate the bufferupon reading a \n.3. Write a C program that will get 10 grades of the student from a file. Get theaverage of the three grades and check each grade if its passing or not. Passinggrade is 70. Store all the passing grade to an output file, and store all the failinggrades to another output file.

1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 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 file into 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.
Please help with C++, CANNOT use array or vector CAN ONLY USE BELOW #include<iostream> #include<fstream> #include<string> #include<iomanip> This program numbers the lines found in a text file. (text file name is story.txt) Write a program that reads text from a file and outputs each line to the screen and to another file preceded (preceding file name outputfile.txt) by a line number. Print the line number at the start of the line and right-adjusted in a field of three spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (that is, wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before…
1. Write a program in C/C++ that reads a table of data from an input file and displays the data. The program then prompts the user to see the data in specific order. The output of your program should display the sorted data (descending order) according to the user selection. Your program should display the prompt repeatedly until the user wants to exit. See the test run. The input file contains four data fields: Country, Total cases, New cases, and Total deaths. The number of rows (data) can vary between 5 to 100. You must use Quick sort in your implementation. Example test run: Country Total Cases New Cases Total Deaths USA 48072665 70590 784775 India 34447536 10560 463655 Brazil 21960766 2799 611384 UK…
Read Data Write a function that reads in data from a file using the prototype below. The function can define and open the file, read the names and marks into the arrays and keep track of how many names there are in numElts, and then closes the file. The list of names and marks can be found at the end of the lab and copied into a text file. void getNames(string names[], int marks[], int& numElts); Display Data Write a function to display the contents of names and marks using the prototype given below. void displayData(const string names[], const int marks[], int numElts); Linear Search Write the searchList function given the prototype below so that it searches for a given name. The functions returns and int which is the index of the name found. The main program will decide if -1 is returned then it will say name is not found otherwise it will write out the name and the mark for that name. int linearSearch(const string list[], int numElts, string value);…
Question 1 of 1: Word Swap: Write a C++ program that will swap the words Caesar and Brutusin the file “source_file.txt”. You will need to load the file “source_file.txt” and finally write theupdated contents with the replaced words to the file “target_file.txt”.Successful operation should swap all occurrences of Caesar with Brutus and Brutus with Caesar.You can use functions from the cstring library. You are not allowed to use the string datatype. Once again, do not use string datatype.Please properly comment your code before submission.

The objective of this question is to generate and read files that contain a list of random numbers. Write a function that generates a file with following parameters: def fillFile(fileSize, fileName): The function should be called to generate files in the following sizes: fileSizes = [1000, 5000, 10000, 20000, 30000, 40000, 50000] The generated files can have names file1000, file 5000, file 10000, file20000, fi130000, file40000, file 50000. You can use random.randint(0.fileSize+1000) to generate a random number. Write another function that reads numbers inside of a file and returns a list. def readFile(fileName): The returned list contains the numbers stored in the file. At each call of fillFile and readFile, record the times before and after the function call as in following example (import time): start = time.time() fillFile(file Size, "file" + str(fileSize)) finish time.time() runTime = finish - start Record the run times of functions into a file named "fileStats.txt".

Write a program in C++ to do the following: 2. Create an array to hold up to 20 integers. 3. Create a data file or download attached text file (twenty_numbers.txt) thatcontains UP TO 20 integers.4. Request the input and output file names from the user. Open the filesbeing sure to check the file state.5. Request from the user HOW MANY numbers to read from the data file,up to twenty. Request the number until the user enters 20 or less, but not lessthan 0. The user enters the number of integers to read. The integers are storedin the file and are to be read from the file.6. Write a function that reads from the opened data file: the numberof integers the user wants to read, and store the numbers inthe array. For example, if the user wants to read 13 numbers,read 13 of the 20 that may be in the file.7. Write a function that writes to the opened output file AND THECONSOLE, the numbers stored in the array.8. NO GLOBAL variables are to be used. The input and output file variablesmust be passed…
in c++ input file is .txt Write a program that asks for the name of an input file. Then, read all the numbers in the file, and display the following information to the screen: count of numbers in the file sum of all numbers in the file average of all numbers in the file (to 2 decimal places) count of numbers in each range (100-199, 200-299, 300-399, etc.) The program should: display a hello message ask the user for an input file display the name of the input file validate the file opens correctly display statistical information as shown above display a goodbye message
