What do you mean by logical error?

In computer programming, a logic error is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally (or crash). A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.
A.

What is difference between syntax error and logical error?

There are generally two types of errors: syntax errors and logic errors. Syntax errors occur when a program does not conform to the grammar of a programming language, and the compiler cannot compile the source file. Logic errors occur when a program does not do what the programmer expects it to do.
  • How do you debug?

    While you navigate code in the debugger, you can inspect the state of your app or learn more about its execution flow.
    1. Start debugging.
    2. Step into code, line by line.
    3. Step through code, skipping functions.
    4. Run to a specific location or function.
    5. Move the pointer to change the execution flow.
    6. Step into non-user code.
  • Why is it important to debug a program?

    Programmers write computer programs in a language we call code. However, because no one is perfect, computer programmers sometimes make mistakes when writing their code. These mistakes are known as 'bugs'. An important part of programming is testing your program and 'debugging' (which means removing the bugs).
  • What is a programming construct?

    A language construct is a syntactically allowable part of a program that may be formed from one or more lexical tokens in accordance with the rules of a programming language. The term "language construct" is often used as a synonym for control structure, and should not be confused with a function.
B.

What happens when a logical error occurs?

Logical errors are the most difficult to fix. They occur when the program runs without crashing, but produces an incorrect result. The error is caused by a mistake in the program's logic. You won't get an error message, because no syntax or runtime error has occurred.

  • What is a compile time error?

    Compile time error is any type of error that prevent a java program compile like a syntax error, a class not found, a bad file name for the defined class, a possible loss of precision when you are mixing different java data types and so on. A runtime error means an error which happens, while the program is running.
