Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Answer:
Glue Language
Explanation:
I'm not 100% sure, but here is the definition.
Glue language- A programming language that can be used to provide interoperability between systems not originally intended to work together
Answer:
The correct answer would be, Laser Printers.
Explanation:
There are a lot of printers that are used to print out a document, or file, or image, or anything you want on a paper. Printers are called the output device of the computer system as it is used to get the output from the computer.
The most important types of printers are Laser Printers, Inkjet Printers, Dot Matrix Printers, etc.
Laser printers are considered to be the fastest printers among all. These printers also give a high quality print out in just a blink of an eye. So these printers are used to print documents which are too lengthy and require a quick print out. So Laser printers will help Calvin in meeting his deadline.
Answer:
#include <iostream>
using namespace std;
int main()
{
char str[100][20];
int n;
cout<<"Strings you want to enter"<<endl;
cin>>n;
cout<<"enter n strings"<<endl;
for(int i=0;i<n;i++)
cin>>str[i];
for(int i=0;i<n;i++)
{
if((int)str[i][0]==98) //ascii value b is 98
cout<<str[i]<<endl;
}
return 0;
}
Explanation:
The above written code is for printing the strings which starts with the letter b.
To check if the string starts with a letter b we are checking the ascii value 98 which corresponds to b and then printing those strings.
Rapid prototyping as it allows the production of a functional program in a short time
