Lvalue and Rvalue error ...

[joshilay]

hi ...
can anyone please tell what are Lvalue and Rvalue errors in c and c++ ???

Like
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.

Yes what Mr. Salem has said is perfect and if you want a more detailed account then you can try here.

@joshilay
I don't think you get rvalue required errors.

@joshilay I don't think you get rvalue required errors.

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

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.
