Question

What do you mean by a temporary instance of a class?

Answer 1

Temporary instances are constructors that live in the memory for as long as it is being used in the expression, in which they have been invoked.eg:-

class test

{

int m;

public:

test(int a)

{

m=a;

}

void print ();

{

cout<<m;

}

};

void main()

{

test t(2);//is an object

test(2).print();//is a temporary instance

}

Answer 2

Answer:

you may wish to use an instance temporarily to invoke a method or chain of methods. Temporary instances are instances that are instantiated in order to invoke a method or chain of methods, then are immediately discarded.
