- When the code below is run, it produces undefined and unpredictable results. Why?Can you suggest an intervention to resolve this issue without removing or changingany of the existing lines of code? (hint: add a line of code) char *myPtr;myPtr = malloc(10*sizeof(char));for (int i = 0; i < 10; i++){myPtr[i] = 'a';}myPtr[10] = '\0';What output is produced by the following code? For each output line, describewhether the line begins or ends with a blank or blanks.String aString = "Jelly beans";double d = 123.1234567890;System.out.println("START1234567890");System.out.printf("START%sEND %n %9.4f %n", aString, d);pls do fast within 5 minutes and i will give like for sure Solution must be in typed form JAVA 1a)Carefully examine the online documentation for the Scanner constructors. Which of the following are acceptable parameters for a Scanner: File, FileInputStream, FileReader. b)Prove 5n4 +3n3 +2n2 +4n+1isO(n4).
- What is the output of the following code fragment? int a = 10, b = 3; boolean answer = ((--a >= 10) && (--b == 20)); System.out.println(a + "," + b + "," + answer);Write a program that meets the followingrequirements:■■ Get an audio file from the class directory using AudioClip.■■ Place three buttons labeled Play, Loop, and Stop, as shown in Figure .■■ If you click the Play button, the audio file is played once. If you click the Loopbutton, the audio file keeps playing repeatedly. If you click the Stop button,the playing stops.write a shell program to get mark details of a student and display total and grade? Attach screen shot of outputs
- Find missing piece of code? And do code, share screenshot with output.Computer Science For each of the code snippet given below, identify the error and then write code after fixing the error. Given code is the simulation of grep -v command. -v prints all lines that do not match a specific pattern. void grep_inverse(char *filename, char *str) { FILE *fp; char buf[buff_size]; fp = fopen(filename, "r"); if(!fp) { perror(filename); } else { while (fgets(buf, buff_size, fp) != NULL) { if ((strstr (buf, str)) != NULL) printf("%s", buf); } } fclose(fp); }Create a file in linux containing more than 17 line. Show only lines 5 -17 of the text file.Provide the screenshoot of the solving as well.
- Write a program that will read the file text.txt which is provided and the encryptedmessage in there. Please write back the decrypted message into the output.txt file.When you see the message in the output.txt file, you need to submit the java codefile. You need to use Rot13 class for decrypting the message. Do not need to submit in the output.txt file. file example: public class FileExample { public static void main(String[]args){ try {//create file object for input.txtFile in_file = new File("src/input.txt");//create file object for output.txtFile out_file = new File("src/output.txt"); //read the input.txt file with ScannerScanner read = new Scanner(in_file);//write the output.txt file with PrintWriterPrintWriter w = new PrintWriter(out_file); while(read.hasNextLine()){w.write(read.nextLine());} //don't forget to closew.close(); // while(scan.hasNext()){// System.out.println(scan.next());// } }catch(Exception ex){ex.getStackTrace();}Java Program ASAP Please pay attention to the screenshot for test case 2 and 3 and please make sure you match the result. Modify this program so it passes the test cases in Hypergrade becauses it says 5 out of 7 passed. import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.util.ArrayList;import java.util.Arrays;import java.util.InputMismatchException;import java.util.Scanner;public class FileSorting { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); while (true) { System.out.println("Please enter the file name or type QUIT to exit:"); String fileName = scanner.nextLine(); if (fileName.equalsIgnoreCase("QUIT")) { break; } try { ArrayList<String> lines = readFile(fileName); if (lines.isEmpty()) { System.out.println("File " + fileName + " is empty."); } else {…Write a method called flipLines that accepts a Scanner for an input file and writes to the console the same file's contents with each pair of lines reversed in order. If the file contains an odd number of lines, leave the last line unmodified. For example, if the file contains: Twas brillig and the slithy toves did gyre and gimble in the wabe. All mimsey were the borogroves, and the mome raths outgrabe. your method should produce the following output: did gyre and gimble in the wabe. Twas brillig and the slithy toves and the mome raths outgrabe. All mimsey were the borogroves,
