The Situation.. Write a class for soccer game scoring. Provide a constructor that starts each team with a score of zero. Include instance variables to keep the score for both teams. Include a method to add 1 to the score of the first team and a method to add 1 to the score of the second team. Include a method that displays the score of both teams, and the Main method to test, creating two different soccer games. Score points so the first game is 3-2 and the second game is 0-1. Display the scores of each game....
can someone solve this??

Which situation constructor is used?
Constructor is necessary when you are about to use instance of a class.
What is difference constructor and function in programming C plus plus?
A Constructor is called when you are making a new instance of a class and member functions are functions that you can call within your class or else call using the instance of that class.for exampleclass Foo {public:int bar;Foo(int bar) {this->bar = bar;}inc_bar(); {this->bar++;}};Foo instance(10); // Constructor is called and bar is set to 10cout
Need of constructor in c plus plus?
There is no specific keyword for a constructor in C++. Simply define and declare a method of the class with the same name as the class and it will be a constructor. A constructor with no arguments is the default constructor, a constructor with one argument of class type is the copy constructor, and a constructor with one argument of some other type is the conversion constructor. You can provide other overloaded constructors if you want.
What does it mean in java when a constructor is undefined?
When a constructor is not define in java then the instance used in class is not optimised the value and therefore some times it generates some garbage value. By the way , When we not define a constructor then generally it not distrub the execution of the program.
What are the 6 ways to use this keyword?
"Java This keyword" is a reference to the current object, it is very helpful when you need to refer an instance of a particular Object from its available methods or using it's constructor, also "this" keyword helps us to avoid naming conflicts.The following are different ways to use java this keyword1) Using with instance variable2) Using with Constructor3) Pass / Return current instanceUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with ConstructorUsing this keyword inside constructor like followingthis("Sony", 20); it will call the constructor having same parameter

Use of constructor?
to create an instance of object
Static can be used in front of a constructor?
No. Static elements belong to the class, and the constructor belongs to the object (which is an instance of a class).
Why you use constructors?
To create an instance of the class that implementing that constructor
How does constructor work?
First line in any constructor has to be either super() or this() not both. If any constructor does not contain either of super() and this(), compiler adds super(). When any constructor is called before excuting the code of the constructor, if it founds this(), it will call another constructor else it will call super() which is the call for the constructor of super class, now again from the super class constructor it will call the super class constructor if available. This is continued until it reaches the top of the class hierarchy. ---- Basically, a constructor is a block of code that gets executed each time a particular instance of a class is created. So, say you've designed a class for working with a database of some sort. When you create an instance of that class, copies of all the variables and functions of that class get attached to the instance-object, and if one of the functions is a constructor function, it will be run as soon as the instance-object is created. This lets you automatically set up conditions for the instance (i.e. establishing connections to different databases or reading data from different tables, or etc.). Depending on the language you're using, classes may or may not automatically call the constructor function of a parent or super class (if such exists, and if you do not provide a constructor for the class in question).

An instance method or constructor may be overloaded by providing the same name and arrgument list?
You can overload instance methods and constructors (ref. Prog. Logic)
How do you get a default constructor?
The default constructor is an empty (only call the super constructor) with no parameters constructor inserted by the java compiler when you don't define a constructor in your class. If you write something like this: public class NoConstructorClass{ //no constructor goes here } Then you get something like this: public class NoConstructorClass{ public NoConstructorClass(){ // Default constructor that you didn't write super(); } }
What is an instance of a class Red many definitions of a constructor But did not understand the exact working of a constructor What is the main use of constructor how it works?
The consttructor creates a new instance of the class for example the class shown below does not exist until the constructor is called, where it sets the class up for first use. Class Dog { int _legs, _eyes; string _breed; //CONSTRUCTOR, this takes an input from the user which sets the breed of the dog, and sets the default number of legs and eyes. public Dog(input) { _legs = 4; _eyes = 2; _breed = input; } } if the user calls the constructor with the string "Labrador", that is one instance of the class, if the user calls it again with the string "terrier" that is another instance. the class is constructed like this: //Class instancename = New class(parameters); Dog lab = New Dog("Labrador"); hope this helps Steve
