Explanation:

A DBA's job is to assure the efficiency, security, and integrity of databases under his care. These objectives correspond to tasks 1, 2 and 3 respectively.

Entering data into databse is a daily operation belonging to the database manager / users, so it is not a DBA's task.

Any file that contains data but not instructions for your computer is not considered software

DIA [1.3K]

True.

But then again, partly false. A .deb file (Debian, Ubuntu Linux) contains data, but that data needs to be installed and marked executable to make the software.

But i would still say true.

Xml provides a standardized, non-customizable way to describe the content of a document.

Rainbow [258]

XML (eXtensible Markup Language) is a meta-language that defines a language (of your creation, within XML specs). The language that you create has to follow your specifications.

Ostrovityanka [42]

Answer:

Explanation:

I have written the Python program based on your requirements.

Just give the path of the input file and the path for the output file correctly where you want to place the output file.

In, my code - I have given my computer's path to the input and output file.

You just change the path correctly

My code works perfectly and I have tested the code with your inputs.

It gives the exact output that you need.

I have attached the Output that I got by running the below program.

Code:

month_list={ "january":"1","february":"2", "march":"3","april":"4", "may":"5", "june":"6","july":"7", "august":"8", "september":"9","october":"10", "november":"11", "december":"12"} input_file=open('C:\\Users\\Desktop\\inputDates.txt', 'r') output_file=open('C:\\Users\\Desktop\\parsedDates.txt','w') for each in input_file: if each!="-1": lis=each.split() if len (lis) >=3: month=lis [0] day=lis[1] year=lis [2] if month.lower() in month_list: comma=day[-1] if comma==',': day=day[:len (day)-1] month_number=month_list[month.lower()] ans-month_number+"/"+day+"/"+year output_file.write (ans) output_file.write("\n") output_file.close() input_file.close()

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:

default constructor.
parameterized constructor.
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
