Complete CapVowels(), which takes a string as a parameter and returns a new string containing the string parameter with the first occurrence of each of the five English vowels (a, e, i, o, and u) capitalized. Hint: Begin CapVowels) by copying the string parameter to a newly allocated string. Ex: If the input is: management the output is: Original: management Modified: mAnagEment 1 #include 2 #include 3 #include 4 5 // Return a newly allocated copy of original 6 // with the first occurrence of each vowel capitalized 7 char* CapVowels (char* original) { 8 /* Type your code here. */ 9} 10 11 int main(void) { 12 13 14 15 16 17 18 19 20 21 22 23 24 25 } 26 char userCaption [50]; char resultStr; scanf("%s", userCaption); resultStr = CapVowels (userCaption); printf("Original: %s\n", userCaption); printf("Modified: %s\n", resultStr); return 0; main.c // Always free dynamically allocated memory when no Longer needed free (resultStr);
Toy encryption scheme. It encrypts plaintexts that consist of only uppercase letters and the underscore character (27 characters total): ABCDEFGHIJKLMNOPQRSTUVWXYZ_ Note that the underscore character is part of the alphabet and will also be encrypted. A key in this scheme consists of 4 digits, each from 0 to 9. Each digit tells how much to shift one character, that is, change it to the character that many positions later in the alphabet. If the shift goes past '_', then we wrap around to the beginning. The key is applied separately to each group of 4 letters in the message. For example, if the message HI_SALLY is encrypted with the key 2407, the H would be shifted by 2, the I by 4, the underscore by 0, and the S by 7. Then we would start over with the first digit of the key, shifting A by 2, L by 4, and so on. So the ciphertext would be: JM_ZCPLE. Give the encryption of the following messages with the key 2641. a. SELL_GME b. FRANZ_IS_MOLE c. DEPLOY_ALL_DIVISIONS
Format String Vulnerabilities: These occur when untrusted input is used as the format string in a formatted output function. This can allow an attacker to read or write arbitrary memory, leading to a security vulnerability. While this is more common with the printf family of functions, it can also occur with iostream if care is not taken. *Can you provide a simple iostream example of a format string vulnerability? How do you correct this vunlerability?*

Compliant/Noncompliant Solutions The following code segment was provided in Secure Coding Guidelines for Java SE: void readData() throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file"))); // Read from the file String data = br.readLine();} The code is presented as a noncompliant coding example. For this assignment, identify two compliant solutions that can be utilized to ensure the protection of sensitive data. Provide a detailed explanation of factors, which influence noncompliant code and specifically how your solutions are now compliant. Your explanation should be 2-3 pages in length. Submit the following components: Word document with appropriate program analysis for your compliant solutions and source code in the Word file. Submit your .java source code file(s). If more than 1 file, submit a zip file.
Javascript: A startup that builds a chat app wants to identify highly social users. All the chat data is in a large log file with three values on each line - the sender ID, receipient ID, and the number of messages. Given a threshold number, find the number of users that appear at least as many times as this threshold.For example:USERA USERB 14USERA USERC 94USERB USERB 3...Note: On the third line, a user sents a message to himself.Inputslogs = a list of lines where each line is a stringthreshold = a numberOutputReturn a list of sorted user IDs. If the same user appears in the same line, only count them once.

Bitcoin script: Alice is on a kayaking trip and is worried that her phone (which contains her private key) might fall overboard. She would like to store her bitcoins in such a way that they can be spent with knowledge of a password. Accordingly, she stores them in the following ScriptPubKey address: OP_SHA1 <0x13818a5684a7ed4dce8433c3f57e13b589b88852> OP_EQUALVERIFY Write a ScriptSig script that will successfully redeem this transaction. [Hint: it should only be one line long.] Explain why this is not a secure way to protect bitcoins using a password. c. Would implementing this using pay-to-script-hash (P2SH) fix the security issue(s) you identified? Why or why not?
Focus on string operations and methods You work for a small company that keeps the following information about its clients: • first name • last name • a 5-digit user code assigned by your company. The information is stored in a file clients.txt with the information for each client on one line (last name first), with commas between the parts. For example Jones, Sally,00345 Lin ,Nenya,00548 Fule,A,00000 Smythe , Mary Ann , 00012 Your job is to create a program assign usernames for a login system. First: write a function named get_parts(string) that will that will receive as its arguments a string with the client data for one client, for example “Lin ,Nenya,00548”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and newlines from the end of the parts. You’ll need to use some of the string methods that we covered in this lesson You can test your function by with a main() that is just the function call with the…
