In the statement mode,  When parser encounters an error anywhere in the statement, it ignores the rest of the statement by not processing input from erroneous input to delimiter, such as semi-colon.

• True

• False

It is not expected from the parser to check for errors but errors may be encountered at various stages of the compilation process.

• True

• False

The Dynamic semantic errors: hard or impossible to detect at compile time, runtime checks are required.

• True

• False

In syntax analysis, a parser is not required to detect and report any error in the program.

• True

• False

In panic mode, when a parser encounters an error anywhere in the statement, it ignores the rest of the statement by not processing input from erroneous input to delimiter, such as semi-colon.

• True

• False

The grammar designers have to be careful here because one wrong correction may lead to an infinite loop.

• True

• False

It is not important to detect errors as soon as possible without further consuming unnecessary input.

• True

• False

In error recovery choose a minimal sequence of changes to obtain a global least- cost correction.

• True

• False

The parser analyzes the ____________(token stream) against the production rules to detect any errors in the code.

• SOURCE CODE

• None of the Above

• LIST CODE

• PROGRAM CODE
