You are required to extend the existing code so that it handles std::invalid_argument exception properly. More specifically, you have to extend the implementation of process_input function. It takes integer as an argument and has to work as follows: It calls function largest_proper_divisor(n). If this call returns a value without raising an exception, it should print in a single line result=d where is the returned value. Otherwise, if the call raises a std::invalid_argument exception, it has to print in a single line the string representation of the raised exception, i.e. its message. Finally, no matter if the exception is raised or not, it should print in a single line returning control flow to caller after any other previously printed output. To keep the code quality high, you are advised to have exactly one line printing returning control flow to caller in the body of…Complete the following TODO sections of this C code // TODO: Spawn a child process ??? = ???; // CHILD CODE // TODO: Conditional for child only if( ??? ){...} // PARENT CODE printf("Parent waiting for child to complete\n"); int status; // used to check return code of child // TODO: Block until child is finished and check the output ????

- A process P forks a child C. After the fork(), both parent and child open() the same file for writing using the flag O_WRONLY resulting in descriptor fd. Subsequently P write()'s out a line containing the single character 1 to fd. C write()'s out a line containing the single character 2 to fd. C write()'s out a line containing the single character 3 to fd. P write()'s out a line containing the single character 4 to fd.

- 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).

Please be advised, I am using PostgreSQL as that is what was used in class. Thus, I must use PLPGSQL Code CREATE OR REPLACE FUNCTION Moreno_03_bankTriggerFunction()RETURNS TRIGGERLANGUAGE PLPGSQLAS$$CREATE TRIGGER Wise_12_bankTriggerAFTER DELETE ON accountFOR EACH ROW EXECUTE PROCEDURE Moreno_15_bankTriggerFunction();My Question starts here In the code linked Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file if a command line argument is given to the program (using your readEmpFromFile function you just wrote). Question ends here To make it easier so that you do not have to go through the entire code I'm going to put writeEmpToFile function right here after the question but if you still need to look at the full code to get an understanding of what you are working with its linked at the bottom void writeEmpToFile(Employee *emp, FILE…
