- I am trying to read in a text file called "lines.txt" that holds an entire dictionary of words with multiple words on each line. I am supposed to find the longest word in the file and the line number it is on. So far I know that I am supposed to have a line counter when initializing the first get line() to 1 but I am confused on how to parse through it.arrow_forwardin C++arrow_forwardEasy way not complicated (for begginer)arrow_forward
- Practice problem we were given in C++ to review for test. Thanks Write a program that reads data from a data file, the value of which is provided at the end of the problem. Your program is to incorporate the following requirements: Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file. Save the output of the program in a file. Write a function called getNumber which reads a number from the input file, outputs the number to the output file and the monitor and sends the input number to the function main. Make sure, both input and out file are being opened in the main program. Write a function called classifyNumber which counts number of even, odd, and zero (occurrences of zero) available in the input file. Have the program find the sum and average of the numbers and print only 10 numbers per line. Write a function called printResult so that it outputs (in output file and monitor) even number of…arrow_forwardGood day/evening , C++ help needed. I am reading in two integers from a file. For example my input.txt file has the integers : “4–5” I am able to open the file and store the first value (4) into variable n but I can't store the second integer value (5) into variable m, I think the computer reads the dash as the next integer instead of the actual integer which is 5, how can I create a code that ignores the dash when searching for the integer in the input.txt? Thank youarrow_forwardIn C++ , please complete the program, whilst avoiding advanced manipulators or strings. Thanksarrow_forward
- How do you write a code in c++ that gives the user an option to save(write) a program(example the program arranges numbers in ascending order) onto a text file.arrow_forwardcan you do it pythonarrow_forwardUsing 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.arrow_forward
- The goal for this question: DISCLAIMER****** CODE MUST BE WRITTEN IN C CODE. NOT C++, C#, etc. To create a program that MUST utilize the functions (argc, argv, char strstr, and possibly even Getline) to, 1. Open a file 2. Read the file 3. Read txt file line by line 4. count up the number of times a specified word is read(HOWEVER! IT CANNOT COUNT MORE THAN ONE WORD PER LINE!) ex. if the code comes across a line in a text file that has the word cookie in it 3 times. It can only count the word ONCE since it is counting line by line. Not all the words added up. 5. then display to the user the total number of lines with the specific word. ex. gcc -o <program name> ./<program name> <file name.txt> <"word to be searched"> then execute a total number of times words came up. Again, only count up by one even if there is that specified word multiple times in one line.arrow_forward- In C++ using Visual Studio - Seperate the files if there is any .cpp, .main or .h files. PART 1Read the contents of the text file and store them in a C++ data structure called std::map<string, int>This map is a collection of sorted <key, value> pairsIn this case, the keys are unique words found in the text file, and the values represent the number of times each word appearsFor example, since the word "cat" appears twice in the file, then map["cat"] = 2 PART 2Iterate through the map and print each key in the order they appearThis will give you a sorted list of unique wordsHere's the expected result: "a big cat does everything feeding goats helping injured juvenile kangaroos locating missing notorious objects playing quietly reading superb tales upvoting videos with xylophone yielding zebras" PART 3Iterate through the map again, this time printing each associated valueThe values represent how many times each word was found in the text filePay attention to the sequence of…arrow_forwardUse the functions from the previous three problems to implement a pro-gram that computes the sum of the squares of numbers read from a file. Your program should prompt for a file name and print out the sum of thesquares of the values in the file. Hint: Use readlines ()arrow_forward
