Which type of error can be detected during compilation process?
Matthew Underwood
Updated on April 20, 2026
From the point of view of when errors are detected, we distinguish: Compile time errors: syntax errors and static semantic errors indicated by the compiler. Runtime errors: dynamic semantic errors, and logical errors, that cannot be detected by the compiler (debugging).
Moreover, what type of error can be detected by the compiler?
All syntax errors and some of the semantic errors (the static semantic errors) are detected by the compiler, which generates a message indicating the type of error and the position in the Java source file where the error occurred (notice that the actual error could have occurred before the position signaled by the
Also, which error is detected at the compilation time? The Differences between Compile-Time and Run-Time Error are:
| Compile-Time Errors | Runtime-Errors |
|---|---|
| It includes syntax errors such as missing of semicolon(;), misspelling of keywords and identifiers etc. | It includes errors such as dividing a number by zero, finding square root of a negative number etc. |
In respect to this, in which phase of compilation process type errors are detected?
During the semantic analysis phase, this type of error appears. These types of error are detected at compile time. Most of the compile time errors are scope and declaration error.
What type of errors can a compiler detect Mcq?
Answer: c. grammatical errors only. Explanation: Compiler is a computer program that detects grammatical errors, not logical errors.

Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic errors are due to identified causes and can, in principle, be eliminated.Which error Cannot be detected by computer?
Logical errors are the errors which a computer can't detect. These errors occur due to incorrect logic in a program.What is a lexical error?
Lexical errors are categorized under this type of error when a lexical item used in a sentence does not suit or collocate with another part of the sentence, these items sound unnatural or inappropriate. In both examples the students use several lexical items which do not suit or collocate with one another.What are two forms of error handling?
Syntax errors, which are typographical mistakes or improper use of special characters, are handled by rigorous proofreading. Logic errors, also called bugs, occur when executed code does not produce the expected or desired result. Logic errors are best handled by meticulous program debugging.What is type checking in compiler design?
 Type checking is the process of verifying that each operation executed in a program respects the type system of the language.  This generally means that all operands in any expression are of appropriate types and number.What are the phases of compiler?
Summary- Compiler operates in various phases each phase transforms the source program from one representation to another.
- Six phases of compiler design are 1) Lexical analysis 2) Syntax analysis 3) Semantic analysis 4) Intermediate code generator 5) Code optimizer 6) Code Generator.
What are semantic errors in C?
It occurs when a statement that is not valid according to the grammar of the programming language. Some examples are: missing semicolons in C++, using undeclared variables in Java, etc. It referred to as semantic error. It occurs when a statement is syntactically valid but does not do what the programmer intended.Which errors can be detected by lexical analyzer?
During the lexical analysis phase this type of error can be detected.Lexical Error
- Spelling error.
- Exceeding length of identifier or numeric constants.
- Appearance of illegal characters.
- To remove the character that should be present.
- To replace a character with an incorrect character.
- Transposition of two characters.
What is three address code in compiler design?
Three address code is a type of intermediate code which is easy to generate and can be easily converted to machine code.It makes use of at most three addresses and one operator to represent an expression and the value computed at each instruction is stored in temporary variable generated by compiler.Which one is the semantic error?
Semantic errors are problems with a program that runs without producing error messages but doesn't do the right thing. Example: An expression may not be evaluated in the order you expect, yielding an incorrect result.Is the phase where errors are detected?
In this phase of compilation, all possible errors made by the user are detected and reported to the user in form of error messages. This process of locating errors and reporting it to user is called Error Handling process.How many parts of compiler are there?
There are 2 part of Compiler.What is YACC in compiler design?
YACC stands for Yet Another Compiler Compiler. YACC provides a tool to produce a parser for a given grammar. YACC is a program designed to compile a LALR (1) grammar. It is used to produce the source code of the syntactic analyzer of the language produced by LALR (1) grammar.What are different error recovery techniques?
Phase level recovery :If a parser encounters an error, it makes the necessary corrections on the remaining input so that the parser can continue to parse the rest of the statement. You can correct the error by deleting extra semicolons, replacing commas with semicolons, or reintroducing missing semicolons.
Are semantic and logical errors same?
In many areas of Computer Science, there is absolutely no difference between a Semantic Error and a Logic Error. Both mean that the program compiled, but the output was wrong. Just as often, they mean two different things. A simple example is intending to use X+1 in your program, but you typed X-1.What is meant by compilation error?
Compilation error refers to a state when a compiler fails to compile a piece of computer program source code, either due to errors in the code, or, more unusually, due to errors in the compiler itself.Is type error a runtime error?
The second type of error is a runtime error, so called because the error does not appear until you run the program. These errors are also called exceptions because they usually indicate that something exceptional (and bad) has happened.What is the difference between compilation error and runtime error?
A runtime error happens during the running of the program. A compiler error happens when you try to compile the code. If you are unable to compile your code, that is a compiler error. If you compile and run your code, but then it fails during execution, that is runtime.How do you solve compilation errors?
Set name misspellings are associated with error 120 , set element misspellings with 170 and other misspellings with 140 . Fixing errors like these is as easy as fixing typos.What is compile time polymorphism?
Compile-Time polymorphism in java is also known as Static Polymorphism. In this process, the call to the method is resolved at compile-time. Method Overloading is when a class has multiple methods with the same name, but the number, types and order of parameters and the return type of the methods are different.Can compiler detect grammatical errors?
A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language, often having a binary form known as object code). Only syntactical errors can be detected by the compiler.What is difference between compile time and run time polymorphism?
Compile-time polymorphism is achieved through method overloading.Java.
| Sr.No | Compile Time Polymorphism | Run time Polymorphism |
