Semantic Phase Errors
Semantic Errors are recognized during the Semantic Phase.
Some of the semantic errors are:
- Incompatible operand types
- Variables that are not declared
- Formal arguments not matching actual arguments
Example:
Int a;
Float b;
a=b;
Here a and b are different data types and are not compatible.
Error Recovery
- A table entry for the corresponding identifier is created when encountered with an “Undeclared Identifier” error.
- Automatic type conversion is done when encountered with two variables of different data types.
