Answer:

Open ended investigation

Explanation:

The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.

From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions

This is a management system in wireless communication that oversees radio resources and crosstalks between two radio transmitters which make use of the same channel.

Explanation:

Radio Resource Management is a management system in wireless communication that oversees radio resources and crosstalks between two radio transmitters which make use of the same channel. Its aim is to effectively manage the radio network infrastructure. Its advantages include;

1. It allows for multi-users communication instead of point-to-point channel capacity.

2. it increases the system spectral efficiency by a high order of magnitude. The introduction of advanced coding and source coding makes this possible.

3. It helps systems that are affected by co-channel interference. An example of such a system is the wireless network used in computers which are characterized by different access points that make use of the same channel frequencies.

Answer:

The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)

#include<iostream>

using namespace std;

string capt(string result)

{

result[0] = toupper(result[0]);

for(int i =0;i<result.length();i++){

 if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' ') {

  result[i+2] = toupper(result[i+2]);

 }

 if(result[i+2]==' ')  {

  result[i+3] = toupper(result[i+3]);

 }

 } }

return result;

}

int main(){

string sentence;

getline(cin,sentence);

cout<<capt(sentence);

return 0;

}

Explanation:

The method to capitalize first letters of string starts here

string capt(string result){

This line capitalizes the first letter of the sentence

result[0] = toupper(result[0]);

This iteration iterates through each letter of the input sentence

for(int i =0;i<result.length();i++){

This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)

if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' '){  ->This condition checks if the sentence is single spaced

  result[i+2] = toupper(result[i+2]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

 if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced

  result[i+3] = toupper(result[i+3]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

}

}  The iteration ends here

return result;  ->The new string is returned here.

}

The main method starts here

int main(){

This declares a string variable named sentence

string sentence;

This gets the user input

getline(cin,sentence);

This passes the input string to the method defined above

cout<<capt(sentence);

return 0;

}

Answer:

B. Full tunnel.

Explanation:

In this scenario, an organization is planning to implement a virtual private network (VPN). They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. The best method to meet this goal is to use a full tunnel.

A full tunnel is a type of virtual private network that routes and encrypts all traffics or request on a particular network. It is a bidirectional form of encrypting all traffics in a network.

On the other hand, a split tunnel is a type of virtual private network that only encrypts traffic from the internet to the VPN client.

Hence, the full tunnel method is the most secured type of virtual private network.

Explanation:

A macro or macroinstruction is a programmable pattern which translates a sequence of inputs into output. It is a rule that specifies how a certain input sequence is mapped to a replacement output sequence. Macros makes tasks less repetitive by representing complicated keystrokes, mouse clicks and commands.

By thoroughly testing a macro before deployment, you are able to observe the flow of the macro and also see the result of each action that occurs. This helps to isolate any action that causes an error or produces unwanted results and enable it to be consistent across end user platforms.

b. Both incremental and iterative development.

Explanation:

Agile software development is based on both incremental and iterative development. It is an iterative method to software delivery in which at the start of a project, software are built incrementally rather than completing and delivering them at once as they near completion.

Incremental development means that various components of the system are developed at different rates and are joined together upon confirmation of completion, while Iterative development means that the team intends to check again components that makes the system with a view to revising and improving on them for optimal performance.

Agile as an approach to software development lay emphasis on incremental delivery(developing system parts at different time), team work, continuous planning and learning, hence encourages rapid and flexible response to change.

Answer:

I am writing the program in JAVA and C++

JAVA:

public int createLicenseNum(int customID){  //class that takes the customID as parameter and creates and returns the licenseNum

       licenseNum = (100000 * customID) + licenseYear;  //licenseNum creation formula

       return(licenseNum);     }

In C++ :

void DogLicense::CreateLicenseNum(int customID){ //class that takes the customID as parameter and creates the licenseNum

licenseNum = (100000 * customID) + licenseYear; } //licenseNum creation formula

Explanation:

createLicenseNum method takes customID as its parameter. The formula inside the function is:

licenseNum = (100000 * customID) + licenseYear;

This multiplies 100000 to the customID and adds the result to the licenseYear and assigns the result of this whole expression to licenseNum.

For example if the SetYear(2014) means the value of licenseYear is set to 2014 and CreateLicenseNum(777) this statement calls createLicenseNum method by passing 777 value as customID to this function. So this means licenseYear = 2014 and customID  = 777

When the CreateLicenseNum function is invoked it computes and returns the value of licenseNum as:

licenseNum = (100000 * customID) + licenseYear;

                     = (100000 * 777) + 2014

                     = 77700000 + 2014

licenseNum = 77702014                                                                                                        

So the output is:

Dog license: 77702014          

To call this function in JAVA:

public class CallDogLicense {

public static void main(String[] args) {//start of main() function

    DogLicense dog1 = new DogLicense();//create instance of Dog class

dog1.setYear(2014); // calls setYear passing 2014

dog1.createLicenseNum(777);// calls createLicenseNum passing 777 as customID value

System.out.println("Dog license: " + dog1.getLicenseNum()); //calls getLicenseNum to get the computed licenceNum value

return; } }

Both the programs along with the output are attached as a screenshot.

Answer:

public int createLicenseNum(int customID){

  licenseNum = (100000 * customID) + licenseYear;

  return(licenseNum);    

}

Answer:

The program written in C++ is as follows; (See Explanation Section for explanation)

#include <iostream>

using namespace std;

void revstring(string word)

{

   string  stringreverse = "";

   for(int i = word.length() - 1; i>=0; i--)

 {

     stringreverse+=word[i];

 }

 cout<<stringreverse;

}

int main()

{

 string user_input;

 cout << "Enter a string:  ";

 getline (std::cin, user_input);

 getstring(user_input);

 return 0;

}

Explanation:

The method starts here

void getstring(string word)

{

This line initializes a string variable to an empty string

   string  stringreverse = "";

This iteration iterates through the character of the user input from the last to the first

   for(int i = word.length() - 1; i>=0; i--)   {

     stringreverse+=word[i];

 }

This line prints the reversed string

 cout<<stringreverse;

}

The main method starts here

int main()

{

This line declares a string variable for user input

 string user_input;

This line prompts the user for input

 cout << "Enter a string:  ";

This line gets user input

 getline (std::cin, user_input);

This line passes the input string to the method

 revstring(user_input);

 return 0;

}

}

else {

   System.out.print((bagOunces * 6)+" seconds");

}

Explanation:

This line checks if bagOunces is less than 2;

if (bagOunces < 2) {

If yes, the string "Too Small" is printed

   System.out.print("Too Small");

}

This line checks if bagOunces is greater than 10

else if(bagOunces > 10) {

If yes, the string "Too Large" is printed

   System.out.print("Too Large");

}

The following condition is executed if the above conditions are false

The fact that the speed of a vehicle is lower than the prescribed limits shall relieve the driver from the duty to decrease speed when approaching and crossing an intersection is not true.

An intersection serves as the point where many lanes cross on the road which is a point where driver is required to follow the traffic rules.

#SPJ2

Answer:

Here is the C++ program:

#include<iostream>  // to use input output functions

using namespace std;     //to identify objects like cin cout

void StartChar(string str)  {  // function that takes a word string as parameter and returns the first letter of that word in capital

   int i;  

   char c;

   do  //start of do while loop

   {

   for (int i = 0; i < str.length(); i++) {  //iterates through each character of the word str

       if(str.length()>25){  //checks if the length of input word is greater than 25

           cout<<"limit exceeded"; }  //displays this message if a word is more than 25 characters long

      c = str.at(i);   // returns the character at position i

       if (! ( ( c >= 'a' && c <= 'z' ) || ( c >= 'A' && c <= 'Z' ) ) ) {  //checks if the input word is contains characters other than the alphabet

            cout<<str<<" is not a word!"<<endl; break;}  //displays this message if user enters characters other than the alphabet

        if (i == 0) {  //check the first character of the input word

           str[i]=toupper(str[i]);  //converts the first character of the input word to uppercase

           cout<<str<<" starts with letter "<<str[i]<<endl;  }  // prints the letter that the word starts with in capital letter

   }   cout<<"Enter a word: ";  //prompts user to enter a word

      cin>>str;   //reads input word from user

}while(str!="#");   }    //keeps prompting user to enter a word until the user enters #

int main()   //start of the main() function body

{ string str;  //declares a variable to hold a word

cout<<"Enter a word: "; //prompts user to enter a word

cin>>str; //reads input word from user

   StartChar(str); }  //calls function passing the word to it

Explanation:

The program prompts the user to enter a word and then calls StartChar(str) method by passing the word to the function.

The function StartChar() takes that word string as argument.

do while loop starts. The for loop inside do while loop iterates through each character of the word string.

First if condition checks if the length of the input word is greater than 25 using length() method which returns the length of the str. For example user inputs "aaaaaaaaaaaaaaaaaaaaaaaaaaa". Then the message limit exceeded is printed on the screen if this if condition evaluates to true.

second if condition checks if the user enters anything except the alphabet character to form a  word. For example user $500. If this condition evaluates to true then the message $500 is not a word! is printed on the screen.

Third if condition checks if the first character of input word, convert that character to capital using toupper() method and prints the first letter of the str word in capital. For example if input word is "Computer" then this prints the message: Computer starts with the letter C in the output screen.

The program keeps prompting the user to enter the word until the user enters a hash # to end the program.

The output of the program is attached.
