Question

write down the disadvantages of the recursive descent paeser?​

Answer 1

Explanation:

Parsing is the process to determine whether the start symbol can derive the program or not. If the Parsing is successful then the program is a valid program otherwise the program is invalid.

There are generally two types of Parsers:

Top-Down Parsers:

In this Parsing technique we expand the start symbol to the whole program.

Recursive Descent and LL parsers are the Top-Down parsers.

Bottom-Up Parsers:

In this Parsing technique we reduce the whole program to start symbol.

Operator Precedence Parser, LR(0) Parser, SLR Parser, LALR Parser and CLR Parser are the Bottom-Up parsers.
