In c++, a reference variable can refer to an object as below
int i;
int &ref = i;
BUT if we put "const" keyword it can take any value, may be some variable or constant value.
Could some one brief me on this?

@Luchian: THe OP is **not** talking about binding a temporary object to a non-const reference. – Deduplicator Jul 02 '14 at 17:01

This is known as const-correctness.
The standard does not define any implicit conversions from cv-qualified to less qualified types, and references act mostly like pointers which can only be assigned once and dereference automatically(Though you cannot bind a non-const lvalue to a non-const reference).
Still, you can use const_cast to override the compiler. On your own head be it then.
