why and where do we use nameless object?

[murari jangid]

tell me past so preparing...why we use this object and what purpose we use it

[weaknessforcats]

Obviously a nameless object can't be referenced by us but it can be referenced by the compiler.

Suppose you have:

string MyFunction();

string x = MyFunction();

Here MyFunction returns a string object that you assign to string x. That returned string object is a nameless object. It only exists to get from the called function back to your string x. Then it disappears.

When you reserve memory using 'new' for say an object,the object is essentially nameless however its address is held by the pointer to which it is assigned...I think.
