(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.
(True/False): When a program's source code is changed, it must be reassembled and linked before it can be executed.
(Remove text) Write a program that removes all the occurrences of a specified string from a text file.
(For example, my mother went to buy groceries while John and I play Call of duty.)
removes the string John from the file.
You should create a file with a paragraph.
removes the string "John and" from the file.
Note:- Please write a java code and also need an output for this program. (Also, let me know with what name file should be saved to get output)

The file contains Item ID, Description and list price stored on a separate line in the file.

- (Use DevC++) 2. Student GradeWrite a program that reads a student name followed by five test scores. The program should output the student name, the five test scores, and the average test score. Output the average test score withtwo decimal places. The data to be read is stored in a file called test.txt. The output should be stored in a file calledtestavg.out. Input: A file containing the student name and the five test scores. A sample input is:Andrew Miller 87.50 89 65.75 37 98.50 Output: The student name, the five test scores, and the average of the five test scores, saved to a file. The program needs to read a student’s first and last name and five test scores. Therefore, you need two variables to store the student name and five variables to store the five test scores. To find theaverage, you must add the five test scores and then divide the sum by 5. Thus, you need a variable to store the average test score. Furthermore, because the input data is in a file, you need an…arrow_forward(True/False): A link library is included in a program right before it generates an executable file.arrow_forward(True/False): The ReadConsole function reads mouse information from the input bufferarrow_forward
- (Check the speed) Write a program that prompts the user to enter the speed of a vehicle. If speed is less than 20, display too slow; if speed is greater than 80, display too fast; otherwise, display just right.arrow_forward(Intro to Java) Only use while loop or for loop. DO NOT use try loop! DO NOT use null. Avoid using breaks! Tracking Customers This program will read in a series of names, along with an associated gender, from an input file of unknown length. The program uses a while loop to read in each name from the file by using the hasNextLine() method from the Scanner class. Please use a while loop for practice, although you could also write this assignment using a for loop to read from the file. As you read in each name, you will store it in an array, along with a title (Mr. or Ms. or Mx.) dependent on the stated gender. The first line of each file will contain the number of names contained in the file (hint: this is the same structure as the input file in your assignment 18.2). Additionally, this program should have two methods, as follows: The first method: The method is named extractInitial It takes a String parameter It extracts the first letter (initial) from the String parameter It…arrow_forwardDO NOT WRITE MAIN! Only write the function. A 50% minimum deduction will be made if main is included. No libraries or comments should be specified. (OP4) Write a function to prompt the user for the filename, open the file, and verify that it opened. If the file does not open, an error message should be printed and the user re-prompted. The function should use the string passed in for the prompt string. The function should not return until the file is open. The function prototype: void openInputFile( ifstream &, string ); ifstream& - the stream to be opened. string - the prompt to be written out to the user. Use this string when prompting the user.arrow_forward
