A compiler maintains two types of symbol tables: a global symbol table which can be accessed by all the procedures and scope symbol tables that are created for each scope in the program.To determine the scope of

One last comment. It's certainly possible to perform compiler optimizations on an executable which has an augmented symbol table, in other words:gcc -g -O9 try1.c. In fact, GDB is one of the few symbolic debuggers which will generally do quite well debugging optimized executables. However,...

When the Java compiler encounters a use of an identifier which it cannot find in the symbol table, it raises the cannot find symbol error. Consequently, the most common occurrence of this error is when there is a reference to an undeclared variable. Unlike some other languages that don’t ...
