A Color class has a method getColorName that returns a string corresponding to the common name for the color, e.g., yellow, blue

, white, etc. If there is no common name associated with the color, null is returned. The class, AlphaChannelColor-- a subclass of Color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. Write the method getColorName of AlphaChannelColor, that overrides the method in the Color class. AlphaChannelColor's getColorName should return the name of the color (obtained from the getColorName method of Color) prefixed with the word 'opaque' if the alpha value is less than 100, 'semi-transparent' if the alpha value is otherwise less than 200, and 'transparent' otherwise (separate the prefix from the color name by a blank). If the color has no name, the method should return "opaque color", "semi-transparent color", or "transparent color", according the the same alpha values as above.

Answer:

public String getColorName() {

String name = super.getColorName();

if (name == null) name = "color";

if (alpha < 100)

return "opaque " + name;

else if (alpha < 200)

return "semi-transparent " + name;

return "transparent " + name;

}

Should I learn Python, C++, C# or VB to start off programming games for Windows. Open to other language recommendations as well!
Svetllana [295]
In theory, you can of course use any language you like, but there are a few commonly used ones.
From your list it would be c++ or c#, because if you actually have the interest long term then those will be the languages used by the various "big"/well known/used engines.
I would suggest c#, because it can be used with the Unity engine, which has an enormous community with help resources especially to start out and learn to program or game development.
On the other hand I would also suggest JavaScript. It isn't used for any of the big title development, but for all the *.io games like slither and so on. When looking at such games you will quickly notice that they are generally much simpler (for example 2D not 3D), because game engines are just simpler in JavaScript. While this is obviously limiting it might help to get something simple actually working, instead of getting stuck in extra complexities and additional features until you lose your motivation.
The basic programming you learn is still the same, so after you have learned a language you can quickly pick up most others.

For each of the following application areas state whether or not the tree data structure appears to be a good fit for use as a s
Cerrena [4.2K]

Answer:

a) Chess game moves:- Tree data structure is not a good fit.

b) Public transportation paths:- Tree data structure is not a good fit.

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit.

d) Genealogical information:- Tree data structure is a good fit.

e) Parts of books:- Tree data structure is a good fit.

f) Programming language history:- Tree data structure is not a good fit.

g) Mathematical expression:- Tree data structure is a good fit.

Explanation:

a) Chess game moves:- Tree data structure is not a good fit. Since in tree data structure moving backward or sharing the node is not that much easy. Presume, In chess, you have to check any box is empty or not. Here, Graph is the best fit.

b) Public transportation paths:- Tree data structure is not a good fit. whenever shortest path, routes, broadcast come always graph is a good option. Because in the tree you don't know how many time you visit that node

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit. Since they have a predefined route. Go to 'c' drive. Open a particular folder and open a particular file.

d) Genealogical information:- Tree data structure is a good fit. Since genealogical information also has a predefined route. Here, the Graph is not suitable.

e) Parts of books:- Tree data structure is a good fit. Since manages the chapters and topics are not that much complex. You can see any book index which is in a very pretty format.

f) Programming language history:- Tree data structure is not a good fit. To store the history of the programming language we need some unconditional jumps that's why the tree is not suitable.

g) Mathematical expression:- Tree data structure is a good fit. The tree is suitable in some cases. We have an expression tree for postfix, prefix.

Write a code segment that takes an emailaddress stored in the string email and stores theuser name in the string user and the ho
iragen [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

int main() {

  string email,username,host;//strings to store email,username,hostname..

  cout<<"Enter the email address "<<endl;

  cin>>email;//taking input of email address..

  bool flag=1;

  for(int i=0;i<email.length();i++)//iterating over the string email..

  {

      if(email[i]=='@')//if @ symbol is encountered make flag 0 skip this iteration.

      {

          flag=0;

          continue;

      }

      if(flag==1)//add to username if flag is 1.

      {

          username+=email[i];

      }

      else//add tom host..

      host+=email[i];

  }

  cout<<"The username is "<<username<<endl<<"The host name is "<<host;//printing the username and hostname..

return 0;

}

Explanation:

I have taken  three strings to store the email address entered by user ,username and host to store username and host name respectively.Then I am iterating over the string email if @ is encountered then skip that iteration before that keep adding characters to username string and after that keep adding characters to host.

Answer:

The answer is "supplierType"

Explanation:

Description of the code:

  • In the given program two structure is defined, that is "supplierType and paintType", in which "supplierType" structure two-variable name and "supplierID" is defined, that datatype is "String and integer".
  • In the next step, "paintType" is declared, in which "supplierType" object supplier is created, in which two string variable "color and paintID" are defined, in which "supplierType" data type is supplied.
