๐ The role of the error handler in the lexical analysis phase is to detect, report, and recover from errors.
๐ก There are various types of errors in lexical analysis that can occur during the compilation process.
๐ ๏ธ Error recovery strategies are implemented to handle errors and ensure the compilation process continues smoothly.
โก๏ธ There are two categories of errors in programming: compile time errors and runtime errors.
๐ Compile time errors occur before the program is executed and can be divided into three types: lexical, syntax, and semantic errors.
โ ๏ธ In lexical analysis, errors can occur if an identifier name has too many symbols.
๐ There are restrictions on the length of identifiers in different programming languages.
โฐ The efficiency of lexical analysis can be affected by the length of identifiers.
๐ Different programming languages have different rules for the length of identifiers.
โ ๏ธ Exceeding the length of numeric constants is considered a lexical error.
โ ๏ธ Numeric constants with illegal characters are considered lexical errors.
โ ๏ธ Using a dollar symbol in a C language statement is a lexical error.
๐ Different types of lexical errors and error recovery strategies in lexical analysis.
๐ง Panic mode recovery: skipping characters until a valid delimiter is found.
โ ๏ธ Transposing two adjacent characters as an error recovery method.
Errors in lexical analysis can be recovered through various methods.
One method is transposing characters to form the correct token.
Another method is inserting a missing character to fix the error.
๐ The video discusses the role of the error handler during the lexical analysis phase.
๐ It explains the different types of errors that can occur during lexical analysis.
โ The video also covers the error recovery measures implemented by the error handler.
