The correct answer is: A. Literal Table
A literal table is a permanent database in the general model of the compiler that stores all of the literals that are used in the program. This includes constants, such as numbers and strings, as well as keywords, such as “if” and “for”. The literal table is used by the compiler to check for errors in the program, such as using a variable that has not been declared, and to generate code that can be executed by the computer.
A literal table is a type of symbol table, which is a database that stores information about all of the symbols that are used in a program. Symbols can be variables, functions, classes, and so on. The symbol table is used by the compiler to resolve references to symbols, such as when a variable is used in an expression.
The literal table is a permanent database, which means that it is not erased when the program is compiled. This is because the literal table is used by the compiler to generate code that can be executed by the computer. The code that is generated by the compiler will need to refer to the literals that are stored in the literal table.
The other options are not permanent databases. The identifier table is a temporary database that is used by the compiler to store information about all of the identifiers that are used in the program. The terminal table is a temporary database that is used by the compiler to store information about all of the terminals that are used in the program. The source code is the program that is being compiled.
I hope this helps!
