COMPILER DESIGN

Detailed explanation-1: -Compiler should report the presence of in the source program, in the translation process. Explanation: Compiler should report the presence of errors in the source program, in translation process.

Detailed explanation-2: -A compiler is a special program that translates a programming language’s source code into machine code, bytecode or another programming language.

Detailed explanation-3: -Explanation: Compiler can only check syntax errors.

Detailed explanation-4: -3) Does the compiler program translate the whole source code in one step? Explanation: The compiler is that program which translates the whole high-level code into the machine code at once.

Detailed explanation-5: -compiler needs to collect information about all the data objects that appear in the source program. The information about data objects is collected by the early phases of the compiler-lexical and syntactic analyzers. The data structure used to record this information is called as Symbol Table.
