3 = myVariable;Will generate an lvalue error, because you can't assign to a numeric constant.You can't assign to a function, or assign to an array either.

can anyone please tell what are Lvalue and Rvalue errors in c and c++ ???Lvalue means location value. And Rvalue means read value.
Suppose the code is
int i;
i=5;
here i is lvalue and 5 is Rvalue.
the code 5=i;
generates error lvalue required.

I don't think you get rvalue required errors.

Maybe he just wanted to know the difference between the L and R values ?
