Concept explainers

Concept of memory addresses in pointers

The concept of pointers in high-level languages was introduced in C programming. Pointers are simply the variables that are used to store memory addresses of another variable. These special variables are generally used in the languages such as C Programming and C++ Programming, where it allows the programmer to work more deeply with memory and its addresses.

Question

Finish rewriting the programming language on page 7 to LL1 grammar. ( Then, start programming a parser based on this LL1 grammar )

Result:
< program >→→ <variable declaration section>; <statements section>
< variable declaration section> int <variable list>
< variable list >→< variable list >, identifier | identifier
< statements section → statements section statement>; <statement>;
< statement > → <assignment statement>|<conditional statement>|<iteration statement>
< assignment statement >→ identifier = <expression>
< conditional statement >→→ if (< condition>) then <nested statement>; else ‹ nested statement >
< iteration statement >→ while (< condition>) do nested statement >
< expression > →→< item >|< expression >+ <item>
< item > → <factor>|< item >*< factor >
< factor > → identifier | integer | (< expression>)
< condition > →< expression> logical_operator < expression>
< compound statement > → begin statements section > end
< nested statement > → <statement> <compound statement>
Possible problem:
left recursion: endless loop -> left recursion elimination
multiple productions: backtracking wastes time -> first and follow set
