(C Language) A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Assume also the maximum number of characters of all file names is 100.

JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList.

PYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 The program works as expected for given input, test 1: Custom Test: Delete file at start Test Contents: import os.path try: os.remove('.test.txt')…
