• Constants in dec, hexa, things like 1L and 1e10 etc

• Check if ordering of the rules is correct

• Identify errors, like for example if a multiline comment is opened, is there a corresponding close, if there are additional close comments (*/)for the same open comment. If there's a semicolon at the end of a #include <stdio.h> for example

• Work on integrating the symbol table in main() using a different file called symboltable.h

As it stands, line numbers for all tokens for all tokens are getting printed as 1.

Consider :

#include <stdio.h>

int main()
{   char b,c,d;
    //int b;

    if(1) {
        int a;
        b = a;
        //func();
    }
}

Current logic only checks if b was declared in its current scope
But what needs to actually happen is, it needs to go to current_scope->parent recursively till it goes to scope 0 to look for an instance of b.
The change needs to be made in parser.y in the logic corresponding to the production id: IDENTIFIER
