class secretType { public: static int count; static int z; secretType(); secretType(int a); void print(); static void incrementY
DanielleElmas [232]

Answer:

The answer to this question can be given as:

In this class definition, there are two constructors.  

Explanation:

In the class definition two constructors are different in type but first we explain constructor that can be as:

Constructor: constructor are special member functions whose task is to initialized as an object of its class.

Rule for defining constructor:

A constructor doesn’t have a return type not even void.

The name of the constructor must be the same as the class name.

A constructor is called automatically when a new instance of an object is created.

Type of constructor:

  1. default constructor.
  2. parameterized constructor.
  3. copy constructor.

In the question there are two type of constructor is used that can be given as:

default constructor:  

The constructor without any parameters is called a default constructor. This type of constructor is called automatically when a new instance of an object is created.

parametrized constructor:

In the parameterized constructor we use at least one parameter in the constructor that is called the parameterized constructor. In the parameterized constructor we can initialize each instance of the class with several values.

Example :

class AB   //define class  

{  

   String name; //define variable

   AB()   //default constructor

   {

   System.out.print("hello...");  //message.

   }

   AB(String name)  //parametrized constructor.

   {  

       this.name = name;  //holding value in name variable.

   }  

}  

class Main  //define class

{  

   public static void main (String[] args)  //main method  

   {  

   AB OB1 =new AB();   //creating class object.

   AB ob2=new AB("XYZ");

   System.out.print(ob2.name);  //print value

   }  

}

Output:

hello... XYZ

solve this simple question 1) Let S = {a, bb, bab, abaab} be a set of strings. Are abbabaabab and baabbbabbaabb in S*? Does any
Mariana [72]

Answer: a.

S = {aa ab ba bb}

This clearly shows that that every string that belongs to this language has an even length including 0 length.

This language can be depicted as following

S* = {∧ aa ab ba bb aaaa aaab aaba aabb bbaa . . .}

Regular Expression for this can be

RE = (aa+ab+ba+bb)*

So S* contains all the strings of a's and b's that have even length. This means all strings of even length.

Explanation:

b.

S* contains all possible strings of a's and b's that have length divisible by 3

This means some of the possible strings examples are:

aaa, bbb, aaabbb, aaaaaa, bbbbbb and so on.

Length divisible by 3 means the length of string such as aaa is 3 which is divisible by 3, also  aaaaaa has length 6 which is divisible by 3

This should be something like this:

(( a + b ) ^3)*

For example a^3 = aaa which is divisible by 3

Regular expression can be:

RE of S* = (aaa + bbb)*

For example string bbbbbbbbb has length 9 which is divisible by 3

So the language is

S* = { ∧ aaa bbb aaabbb aaaaaa aaaaaabbb...}

Help! I turned on my computer and this screen came on out of nowhere, I don't know what to do to fix it.
babunello [35]

Here are the steps I would do:

Do a "hard" power off. Hold the power key until the screen turns off. Wait 10 seconds. Turn it on. If it still shows the screen... then i'm not sure.

The error is occurring because it has nothing to boot off of. It's probably something wrong with your hardware. The instructions say for you to insert a "boot disk" and press any key.
