What can a company do to ensure that its IT architecture and infrastructure are secure? Discuss specific tasks that can be done to help manage risk.

This program is used to split the input based on the delimiter. Change the code below so that the parse function should return an array that contains each piece of the word. For example, the input to the function would be something like 'aa:bbbA:c,' which would be a char *. The function's output would then be a char ** where each element in the array is a char *. For this example, it would return some result where result[0] = 'aa', result[1] = 'bbbA', and result [2] = 'c'. So instead of doing the printing in the parse func, return each piece of the word, pass it to the main function, then do the printing in the main

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void parsefunc (char, char*);
int string_length (char*);
char* my_strncpy (char*, const char*, unsigned int);

//Main Fucntion
int main(int argc, char *argv[] ) {

   if(argc == 1 || argc == 2){
       printf("Not enough arguments, please enter three agruments with program name, delimiter and text! \n");
   }
   else{  
   parsefunc(*argv[1], argv[2]);
   }

}

//This function is used to splip up the string and print the results
void parsefunc(char delimeter, char *input){
int count = 0;
int current = 0;
int length = strlen(input);

   //Loop through the string
for (int i = 0; i < length; i++){
       //Check for delimiter
if(input[i] == delimeter){
  
char* tempString = malloc(sizeof(char) * (count + 1));
strncpy(tempString, input+current, count);

           tempString[count+1] = '\0';
//printf("%d\n", current);
current += count+1;
printf("%s Length %d\n", tempString, count);
count = 0;
           free(tempString);

}
       //Check for delimiter
       else if(input[i+1] == '\0'){
char* tempString = malloc(sizeof(char) * (count + 1));
strncpy(tempString, input+current, count+1);

           tempString[count+1] = '\0';
//printf("%d\n", current);
current += count+1;
printf("%s Length %d\n", tempString, count+1);
           free(tempString);
}else{
count++;
}

}
}

I need a program which tells me if three individual straight line segments form a plane two-dimensional triangle. All three segments will have positive lengths. For example, the three segments 2.5, 3.4 and 5.3 will form a triangle but 1.7, 2.4 and 7.5 will not. If the user enters a zero value, it will be rejected. But if a negative number is entered, it will be changed to the corresponding positive value. Please keep in mind that the length of the longest segment must be less than the sum of the lengths of the other two segments.

The program will accept the three lengths of the segments using the iostream acceptance and testing syntax. Then, it will use a C++ class and a C++ object of that class to find the longest of the three segments and to test whether the three segments will form a triangle. If the three segments will form a triangle the method of your class will return the Boolean value true to the program’s main. Otherwise, it will return the Boolean value false to the program’s main. Then the program’s main will report the result as a text answer to the user, either “true” or “false” and then terminate.

Build the 7-segment decoder for BCD using a ROM (in logisim)

A graph consists of nodes and edges. An edge is an (unordered) pair of two distinct nodes in the graph. We create a new empty graph from the class Graph. We use the add_node method to add a single node and the add_nodes method to add multiple nodes. Nodes are identified by unique symbols. We call add_edge with two nodes to add an edge between a pair of nodes belonging to the graph. We can also ask a graph for the number of nodes and edges it contains, and for a list of its nodes and edges. The to_s method returns a string representing the graph's adjacency lists. Methods should not change the graph if called with invalid arguments; e.g., adding an edge that is already in the graph or that references a node that does not already belong to the graph. Your code does not have to generate the exact transcript that follows but it should provide this basic functionality.

>> g = Graph.new
=> 
>> g.add_node(:a)
=> a

>> g.add_nodes([:b, :c]) => [:b, :c]
>> g
=>

>> g.get_nodes
=> [:a, :b, :c]
>> g.nbr_nodes
=> 3

>> g.add_edge(:a, :b) => [a, b]
>> g.add_edge(:b, :c) => [b, c]

>> g
=> 
>> g.get_edges
=> [[a, b], [b, c]]

>> g.nbr_edges
=> 2
>> puts g
a -> b

b -> a,c
c -> b
=> nil

Create a Song class that has member variables for a title and an artist. It should have a prompt function that asks the user for the title and artist, and a display function that displays the title and the artist to the screen.

Create a deque of songs for your playlist.

Set up a main loop that asks the user for one of the following options:

Add new song to the end of the playlist.

Insert a new song at the beginning of the playlist (so it will play next).

Play a song (this should remove it from the playlist).

Implement each of the above actions. For the ones that add a new song, it should prompt the user for the values, and then add the song to the play list.

When the user selects the option to play a song, it should be removed from the list. Then, display a message to the user, "Playing song:", followed by the title and the artist of the song that was just removed from the front of the playlist.

If the user attempts to play a song and the playlist is empty, they should receive a message that informs them the playlist is empty, and then they can make another selection. (A Python error message should not occur and be displayed.)

Options: 1. Add a new song to the end of the playlist 2. Insert a new song to the beginning of the playlist 3. Play the next song 4. Quit Enter selection: 3 The playlist is currently empty. Options: 1. Add a new song to the end of the playlist 2. Insert a new song to the beginning of the playlist 3. Play the next song 4.

Create a class called MathOperations that a teacher might use to represent the basic type of mathematical operations that may be performed. The class should include the following:

1. Three double private variables as instance variables, number1, number2, and result.

2. Your class should have a default constructor that initializes the three instance variables to zero.

3. Your class should also have a constructor that initializes the two instance variables (number1 and number2) to the value entered by the user from keyboard.

4. Also provide an accessor (getter) and mutator (setter) method for each instance variable except the result, that only has an accessor method.

5. In addition, provide 4 methods called addNumbers(), subNumbers(), divNumbers() and mulNumbers() that calculate the relevant addition, subtraction... operations on the two numbers entered by the user and stores it in the result variable.

6. Create a main method and within this method create 2 objects (obj1, obj2) of the MathsOperations class that sets/initializes the two instance variables (number1 and number2) by values entered by the user from the keyboard (Hint: Use Scanner class object).

7. Call/invoke each method on these 2 objects and print the result of each operation performed (using the result getter method).

8. Note: Please make sure to check when performing a division operation that the denominator is not zero. If the denominator is zero then simply set the result to zero. (Hint: Use condition statements)

Java Program

Suppose a student was taking 5 different courses last semester. Write a program that

(a) asks the student to input his/her name, student ID, marks for these 5 courses,

(b) calculate the average,

(c) determine the letter grade of each course.

(d) record the number of courses whose final letter grade is A+, A, A-, .... , F+, F, F-.

(e) Output the following information in a nice format: student name, student ID, listing of marks, the average, letter grade for each course, and the number of courses in each letter grade category.
