What are the differences between C and Java reference variables?
Java does not have the concept of Reference Variables. We cannot access the memory location where the data is stored in Java.
What are those languages under in object oriented programming?
Most modern programming languages have some support for object-oriented programming. In some (such as Java), it is obligatory - you have to write your code in classes. In others - such as JavaScript or PHP - it is optional, meaning that you can write programs the old-fashioned way (procedural programming).
What is the difference between classes and interference?
The two are totally unrelated. Classes means categories. It is also used as a programming concept. Interference is a phenomenon that happens when two waves meet.
What are the different storage class in c?
The four storage classes in C are: automatic, static, external and register. Note that storage classes are not classes in the object-oriented programming sense, they simply define the scope (visibility) of a variable.Automatic Variables (auto)All local variables are automatic by default so we seldom see the auto keyword in code. Local variables are variables declared at function scope.Static Variables (static)All global variables are static by default. Global variables are variables declared at file scope (outside of any function). Static variables can also be explicitly declared inside functions to override the default automatic storage class. All static variables, whether global or local, are allocated within the program's data segment (static memory) and do not fall from scope even if declared locally. All static variables are initialised to zero by default.It's best to avoid the use of global variables unless they are declared constant (const) as it can be difficult to keep track of all the places where a global variable is being operated upon (accessed or assigned to). This can lead to data races in multi-threaded applications unless we take steps to synchronise all access and assignment operations upon the variable. For that reason it's best to keep variables as localised as possible, passing arguments into functions whenever we need to cross scopes. Non-constant global variables should really only be considered if they truly represent a global concept within the file in which they are declared.External Variables (extern)External storage can only be applied to a global variable declared outwith file scope. That is, when a global variable is declared in one file, any external file can gain access to that same global variable simply by declaring the same name and type but with external storage. It follows that external variables are also static variables and is the only case where a variable has two storage classes. Note the local static variables (including local constant variables) cannot be declared external, they are local to the function in which they are declared.This is another reason why it is best to avoid using too many global variables. While we can generally keep track of which code can access a global variable at file scope we have no means of limiting access from outwith that file. Again, prefer local variables to global variables whenever possible.Register Variables (register)A register variable is a variable that we wish to allocate to a CPU register rather than in RAM. Register variables must be no larger than the word-length of the machine and should only be used when we explicitly require fast access to the variable, such as loop counters, accumulators and pointer variables. Note that CPU registers have no address (no identity we can refer to) so we cannot use the unary '&' operator to take the address of a register variable. This means we cannot use pointers to refer to them indirectly which, in turn, means we can only pass them to functions by value (not by reference). However, to do so would defeat the purpose of using the register storage class.Given the limited number of registers available, there is no guarantee that a register variable will actually be allocated to a register; the register keyword is merely a hint to the compiler. It should be noted that modern compilers are extremely good at optimising code so there is seldom any need to explicitly declare register variables.
What is the difference between C programming and CPP programming?
C has no object oriented support. C++ is a superset of C that adds object-oriented support, but retains the concept of primitive variables. C# is a superset of C++, developed by Microsoft, that removes the concept of primitives, making it fully object-oriented but, unlike C and C++, is non-generic and is only useful for .NET programming. C# is not unlike Java, but Java is fully cross-platform and therefore has much wider support.
Why Airbus A380 super jumbo aircraft unveiled?
It was unveiled for luxury travel and as a concept to see what can be engineered to fly.
Why do classes exists?
Classes exist in programming to help organize and structure code by grouping related variables and functions together. They enable code reusability, encapsulation, and allow for easier maintenance and modification of code. Classes also support the concept of inheritance, allowing child classes to inherit properties and methods from a parent class.

What are the uses of Composite Function in real life?
a) Define the concept of culture. Also describe the national cultural variables and individual cultural variables with examples.
What is the difference between a concept and a variable and How does a researcher transform one into the other?
A concept is an idea or an abstraction that stands for something. A concept becomes a variable when it is made operational or when it can be counted, categorized, or observed. For example, job satisfaction is a concept, but, it becomes a variable when a definition is it attached to it that makes it measurable. You may ask a married person, "how satisfied are you with your job?" If you attach levels of satisfaction to it, then it becomes a variable. All variables are concepts when you can measure the concept. However, not all concepts can be variables. A concept that is not a variable is a concept that is not measurable.
Differences between concept construct and variables?
A concept is an abstract idea or general notion, while a construct is a theoretical idea that is created to explain or represent a concept. Variables, on the other hand, are measurable quantities that can vary or change in a study. Constructs help define and operationalize concepts into measurable variables for research purposes.
When was the marketing concept born?
In 1951 the earth moved. That was the year marketers first embraced the marketing concept. The marketing concept decrees that customers should be the focal point of all decisions about marketing mix variables.

Learning concept?
Concept learning describes the process by which experience allows us to partition objects in the world into classes for the purpose of generalization, discrimination, and inference.
Do you have pointer concept in c plus plus language?
Yes. All string variables are pointers as are other arrays.
