Error detection and Recovery in Compiler - GeeksforGeeks

The program errors are detected and reported by parser. The parser handles the errors encountered and the rest of the input is parsed. The errors may be encountered at various stages of the compilation process. At various stages, the following kinds of errors occur:. In order to deal with the errors in the code, the following are the four common error-recovery strategies:. When an error is encountered anywhere in the statement, the rest of the statement is ignored by not processing the input from erroneous input to delimiter such as semi-colon.
