Regular languages are closed under complement. True False

Computers and Technology
1 answer:
aivan3 [116]3 years ago
4 0

Answer: True

Explanation:

A language is said to be closed under a operation here the complement is the operation then if upon application of that operation to any members of that language always yields a member of that language.

regular languages are closed under complement. A proof of the statement is

If a regular language 'L' is regular then there is a DFA X recognizing that regular language 'L'. to show that L' (compliment) is regular we need to have another DFA X' recognizing L'.

The initial state and transition function of both the DFAs are same except their accepting state. Then we can say that X' accepts L'.

So, we can say that regular languages are closed under complement.

ohaa [14]

Answer:

Check the explanation

Explanation:

(a) There will be a need for the database to support a comparatively complex and complicated hierarchical internal record structure that may vary for each record. Column store NoSQL DBMS

(b)The key requirements for the database are to access a specific record structure as quickly as possible without any concern regarding the internal structure of the record. Key value store NoSQL DBMS

(c) The data are specifically well suited to be organized as a network of connections amid the data items. Graph Base NoSQL DBMS

(d) It is essential that the DBMS offers quick access to each of the records by a key value, but, in addition, it has to also allow easy access to the components of each record. Document store NoSQL DBMS

If the object instance is created in a user program, then the object instance can access both the public and private members of
rewona [7]

Answer:

False

Explanation:

The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class  .The public member are accessible inside the class so they are accessible by using the dot operator .

<u>Following are the example is given below in C++ Language </u>

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {     return 3.14*r*r;  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 3.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Output:

compile time error is generated

<u>The correct program to access the private member of class is given below </u>

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {    

r1=r;

double t2=3.14*r2*r2;

return(t2); // return the value  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 1.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Therefore the given statement is False

How does a paper prototype minimize constraints when compared to a digital one
aksik [14]

A regular prototype minimizes constraints if compared to a paper one because possible problems in use can be identified easily.

<h3>What is a prototype?</h3>

This refers to the initial model of a product designed to test the features of the model before it is released to the market.

<h3>What are the differences between digital and paper prototypes?</h3>

Online protoypes are often time-saving, however, because some features of the prototype cannot be tested, a regular protoype is much better to identify possible problems in design or use.
