Solved in 2 steps
- Write a program that reads strings from the user and writes themto an output file called userStrings.txt. Terminate processingwhen the user enters the string "DONE". Do not write the sentinelstring to the output file.3. Write a function which reads an already existing file “File1.txt” and write digits (0-9) in to a new text file “mynumber.txt” and non digits into a file “Text.txt”.in c++Write a program that removes all the occurrences of a specified string from a text file.Removes the string from the specified file. Your program should get the arguments from the command line.
- a. What happens if you try to move the file marker past the end of a file? b. What is returned if subsequent calls are made to read the file?Suppose a file “ABC.txt” contains three integers separated by commas. Write a program that use the existing file, read the integers and display them in reverse order separated by spaces. Secondly, get string input from user and append an existing file. Finally, count the number of words in a filemake four text files(with extension of .txt), each of these files includes number(at least 20 rows and each row includes an integer number). Then write a C++ program that asks user "Which file do you want me to open?" then you get the name that user entered and validate the name(if the name that user is entered is not one of the four names of your file, then you print error and ask user to enter the name again). When user entered a valid name(means a name that exists), then open the file and find all even numbers in the file and print them out.(you don't need to write the output in the file.)
- Write a program that writes 100 integers created randomly into a file. Integers are separatedby a space in the file. Read the data back from the file and display the sorted data. Yourprogram should prompt the user to enter a file- name. If the file already exists, do not overrideit.Read a source file name (text file) from the user (e.g, myprog.cpp) and produce a copy ofthe same. Also display the following statistics:1. Number of lines of the code?2. Total characters?Write a program that reads data from a file specified by the user at runtime (i.e. your program should accept the filename as user input) and stores the output in the file Ch3_Ex5Output.dat. To test your program, use the Ch3_Ex5Data.txt file.
- Write a program that asks the user for a file name and a string to search for. The program should search the file for every occurrence of a specified string. When the string is found, the line that contains it should be displayed. After all the occurrences have been located, the program should report the number of times the string appeared in the file.A file contains only spaces, commas, colons, digits, and newlines in the following frequencies: colon (100), space (605), newline (100), comma (705), 0 (431), 1 (242), 2 (176), 3 (59), 4 (185), 5 (250), 6 (174), 7 (199), 8 (205), 9 (217). Construct Huffman code.Write a program that reads a text file which has a poem written in it. (Write down the poem yourself in a text file manually). Your program should display that poem and count total number of lines in the file.
