- Write a program to copy an existing text file from your hard disk to another file that you will call: Your Last Name.txt, e.g. if your last name was Smith, the output file name would be Smith.txt. You can create a text file and add two or three lines of text to it. You may use the attached program as your program or write your own. Please note the inclusion of at the top of the program. Also pay attention to the open and close statements in the program. // File: CopyFile.cpp // Copies file InData.txt to file OutData.txt #include // for the definition of EXIT_FAILURE #include // required for external file streams #include using namespace std; // Associate stream objects with external file names #define inFile "InData.txt" #define outFile "OutData.txt" // Functions used ... // Copies one line of text int copyLine(ifstream&, ofstream&); int main() { // Local data ... int lineCount; // output: number of lines processed ifstream ins; // ins is…Write a python program that asks the user for the name of a file. The program should display only the first five lines of the file’s contents. If the file contains less than five lines, it should display the file’s entire contents. Thanks so much for your help!Write a program which reads the content of a file given as input and counts the number of thewords in the file. It is assumed the words are separated by one or multiple of the followingcharacters: ’ ’ ’,’ ’?’ ’!’ ’.’ ’\t’ ’\r’ ’\n’. input: words.txt output: The file contains 17 words. Please write in C programming language.
- 1. Write a program that asks the user for the name of a file. The program should display only the 3 lines of the file's contents. If the file contains less than 3 lines, it should display the file's entire contents. Use the file: lorem_ipsum.txt to test your program. Comment your source code and describe your code to someone who may be viewing it for the first time. PLACE SCREENSHOTS OF THE PYTHON CODE AND ALL I/O BELOW. Please use Python ProgrammingWrite a small program that copies everything in a tet file to another file. The text file is calledin.txt and the output file is called out.txt. Two files should be exactly the same after copying(the first file shouldn’t be changed, and the second file should be the same as the first one).Your program should define a function called copyFile to copy the input file to the output filewith two arguments: a file pointer to the input file and a file pointer to the output file. You shouldnot and do not need to use an array during copying.The program will prompt the user to enter the file names for a source input file and an output file along with two strings, one to be found in the source file and a string that will replace each occurrence of that string in the file. source file: this is the text file that your program will read and search for the target string to be replaced output file: this is the file that will contain the source file after all of the occurrences of the target string have been found and replaced by the replacement string target string: this is the string your program will search for in the source file to locate all occurrences of the string replacement string: this is the string that will replace each occurrence of the target string in the source file I cant use the replace method, count method, split method, range() function, or lists in my solution is there any other method to use to get this.

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
- Write program that reads a list of names from a data file and displays the names to the console. The program should prompt the user to enter a filename. Create such a file and check your code. Solve with python. Example of code format: #Prompt the user for file name file_name = input("Enter file name : ") #Open file with open(file_name,"r") as file: #Read file content f = file.readline() #split the contents into numbers numbers = f.split(' ') test_list = [int(i) for i in numbers] res = 1 #Find the product for i in test_list: res*=i #Print result print("Product of numbers in the list :",res)Write a program which reads from the keyboard the names of two files containing two doublenumbers. Your program should read these two values from the two files, compute their sum, dif-ference, product and division, and write the results on separate lines into the file “results.txt”.You can safely assume that the input is valid, the two input files exist and each contains one validdouble value.(please solve in C programming language).Write a program which reads the first two characters from the file “chars.txt” and writes thesum of their ASCII code values as a number into “codesum.txt”. Use an editor to create theinput file “chars.txt”. Your program is responsible to create the output file “codesum.txt”.You can safely assume that the content of the input file will be valid.(Please write in C programming language).
