- Explain Which pattern will match all filenames containing a "b"? [!b]* *b* *b b*The "gets" function will read a whole line of text from file into a char[] so long as the line of text ends with a '\n' character. True False3.Which of the following will read a string from a file with FILE* fpto char myString[81] properly (safely): fscanf(fp, "%s", myString ); fgets(myString, fp); fgets(fp, 81, myString); correct : fgets(myString, 81,fp) fscanf(fp,"%80s", myString); 4. If you issue the statement fpIn = fopen("myfile.dat", "a");and dat does not exist, the computer will: return NULLto fpIn as the file does not exist create the file in write mode, and position the file pointer at the beginning of the file create the file in write mode, close the file and return a warning open a file that most closely resembles the name 'myfile.dat'

- The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.Could you help me write a C++ code to do the following: Create a program that asks the user for the name of a file and thenrearranges the contents of the file so that its lines are in alphabetical order.The program should modify the file, not print its contents to the screen.Use the STL algorithm sort.*Code in Python Write a script named dif.py. This script should prompt the user for the names of two text files and compare the contents of the two files to see if they are the same. If they are, the script should simply output "Yes". If they are not, the script should output "No", followed by the first lines of each file that differ from each other. The input loop should read and compare lines from each file, including whitespace and punctuation. The loop should break as soon as a pair of different lines is found. Below are examples of the program input and output along with relevant files: one.txt: This is text. abc 123 sameAsOne.txt: This is text. abc 123 differentFromOne.txt This is text. xyz 123 Comparing files that are the same: Enter the first file name: one.txt Enter the second file name: sameAsOne.txt Yes Comparing files that are different: Enter the first file name: one.txt Enter the second file name: differentFromOne.txt No abc xyz
- *Coding in Python A comma-separated value file stocks_data.csv download contains historical data on the Adjusted Closing Price for 3 stocks daily from Jan 2, 2009 to Dec 31,2018.
