When you work with passing by value C creates a copy of the variable which is referencing to. Thus, it spends free RAM space just to dublicate the variable which already excists.When you work with passing by reference type C works with address of the variable, what makes using of free RAM space more efficient.

What is the reference type and value type?
In C#, a reference type [of object] is an object created from a class, a value type is an object created from a struct. 2 value type of objects are identical if their value/state are the same, while reference type are identical only if their storage address are the same. In C#, unless you can look at the definition of an object, usually you don't know the object is a value type or reference type. public struct MyThing {} public class Toy {} MyThing cat = new MyThing(); MyThing dog = new MyThing(); Console.WriteLine(cat yours); // False

What is a reference variable in c plus plus?
A reference variable in C++ is a formal parameter of a function call that automatically dereferences itself, as if it were a pointer, into a reference to the original value in the calling routine. You declare the reference type in the function declaration and prototype, but the compiler automatically adds the reference (&) operator on call, and the dereference (*) operator on use.
What type of cell reference is c?
C is not a cell reference. C is a column reference, but you would need a row number to add to it to make a cell reference, like C2 or C35 or C527 etc.
What is a pointerin c?
Pointer in C are fun to programming.Pointers in C are variables which doesn't stores the value but points to the address where the value is stored.They are used for reference.
What mean by reference function in c?
Reference function has no meaning. Variables are passed to functions by reference or by value, depending on the function signature.
