Step by step
Solved in 2 steps
- Part Two: Implementing a rainbow table You are to write a program, in C/C++, Java or Python, that should run using the following instruction: $ ./Rainbow Passwords.txt where the file Passwords.txt contains a list of possible passwords. The password file contains a password per line, as in the provided words file and consists of strings of printable characters. Any password used must be taken from this file, so the only stored hash information needs to relate to those entries in the file. The program is used to find pre-images for given hash values. Rainbow tables can be used to solve pre-image problems for hash functions. At the simplest level they can simply be a list of hash values and the corresponding pre-images, often from some dictionary. This can be expensive in terms of storage space however, and a more efficient way of identifying pre-images involves the use of the hash function and reduction functions. First step The process is as follows: 1. Read in the list of possible…Using onlinegdb, you're to place these two function prototypes in a file named OddEven.h: // Programmer: . . . // Description: Prototypes for functions to determine if the passed // integer value is odd or even. // Pass in the integer value to be tested. // Function returns "true" if the value is odd. // Function returns "false" if the value is even. bool IsOdd(int value); // Pass in the integer value to be tested. // Function returns "true" if the value is even. // Function returns "false" if the value is odd. bool IsEven(int value); Next, you are to implement the two functions, placing the code in a file named OddEven.cpp. Finally, you are to implement your main C/C++ program placing the code in a file named main.cpp. The program should do the following: 1. Prompt the user to enter an integer value. 2. Check the user input and re-prompt if the value input has a fractional part. 3. Take the integer value input and make calls to the functions to determine if the value is odd or even,…Written using code C++. Only use the headers <iostream> and <fstream>. Do not utilize any additional headers. Thank you! Write a program that reads a file encoded with the "rot13" cypher, decodes it, and stores the decoded file. The decoded file name should be the original file name with the word "coded" attached.
- We have to write Code in C language with the help of Linked list That perform following tasks . Search and display the contents of file based on name, age and salary of employees. Sort the data in ascending order based on the name (alphabetical order), age or salaryof employees.Edit the records and write the updated records back on the file.The file is in text mode, the user should be able to save this file (with a different name) in the binary mode.Using only BufferedReader and BufferedWriter to read/write files and only arrays for any data structure needs, create a static method reverseLineOrder which accepts the arguments: Filename to the input file as a String Filename of the output file as a String The method will create a new file with the lines from the given data set in reverse order. Data.txt: 1 2 3 4 5 6 7 8 9 0 9 8 7 6 5 4 3 2 1 0 8 7 6 5 4 3 2 1 0 9 Subject: Java Programming(a) Given the following method header: public boolean addMovie(Movie movie) Complete the implementation of the method above to insert a new movie into the Movies table in thedatabase. Your method should return true if an insert is successful, and false if an insert fails. You candetect a successful insert through the number of rows returned after the execution of a query. UsePreparedStatement in your answer and include the appropriate exception handling. The Movie classand database table structure specifications are shown in Figure 2.1 and Figure 2.2 below:
- Verify that seven ADT list procedures, list index out of bounds exception, and list exception work.Did I correctly do this function? Did I correctly do the precondition and postcondition? //Precondition: flag_position is a non-negative integer and hBit_flags is a handle to a valid Bit_flags object.//Postcondition: returns the value of the flag at index flag_position if it is in bounds or -1 otherwise.int bit_flags_check_flag(BIT_FLAGS hBit_flags, int flag_position){Bit_flags* pBit_flags = (Bit_flags*)hBit_flags;int i = flag_position / 32;flag_position %= 32;return ((1 << flag_position) & (pBit_flags->data[i])) != 0;if (flag_position <= pBit_flags->capacity) { return *pBit_flags->data;}else{ return -1;}}There are two program below, please describe all the bugs you found and how you fixed them. Step 1: Follow the Demo To use GDB, you need to compile your program with a debugging (-g) flag gcc --std=c99 -g [some_program.c] -o [exe_name] Then, run gdb with the executable: gdb ./[exe_name] Step 2: Use GDB to resolve the segmentation fault Try to use GDB to debug the program buggy-list-sort.c. The program in buggy- list-sort.c specifically generates a short linked list containing random integers and tries to sort it using bubble sort. However, something in the code is broken, and the program crashes with a segmentation fault before the sorting is complete. If you were able to successfully debug the program, make sure to describe all of the bugs you found and how you fixed them in list_sort.txt. (3 pts) Step 3: Use GDB to resolve the logic error Try to use GDB to debug the program buggy-array-sort.c. This program generates a small array of random integers and tries to sort it using…
