#self doubt

Question

int 7=10;

It is a semantic error or syntax error?

My thinking is that it can be tokenized as id id = id ;….So it is valid statement...so it must be semantic error?

Correct me if I am wrong.

Comments

First of all 7 and 10 these are not identifier these are constant. And int is not an identifier it’s a keyword.During tokenization in lexical analyzer phase there will be no error as all are valid lexeme.

int constant=constant; syntactically it’s correct because it is just a assignment.

But semantically it is wrong. Because you LHS of an assignment statement can not be constant.

Correct me if I am wrong.

I am thinking that only...that it would should be semantic error...bcz all are valid tokens and this is valid according to syntax analyzer
