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. Syntax errors are usually easy to fix because the compiler will tell you where the error occurs and you simply fix the syntax error. For example you may miss a semicolon or a curly bracket where it’s supposed to be. Simply locate those errors and fix them. The real pain in the neck are logic errors. For instance you may be writing a software application that solves a puzzle, but when you run it it tells you that the puzzle cannot be solved. After you dig through the program logic you realize you have done something wrong. After you fix the logic and run the program again it solves the puzzle successfully. Logic error
in a high-level language there are two types of errors that they might make: syntax errors and logic errors. Syntax errors are mistakes such difference between syntax error and logical error in java as misspelled keywords, a missing punctuation character, a missing bracket, or a

missing closing parenthesis. Nowadays, all famous IDEs such as Eclipse, NetBeans, and Visual Studio (to name a few) detect these errors
Logical Error Example
as you type and underline the erroneous statements with a wavy line. If you try to execute a program that includes syntax errors, you will get error messages http://www.programmingincpp.com/syntax-error-versus-logic-error.html on your screen and the program won’t be executed. You must correct all the errors and then try to execute the program again. Logic errors are those errors that prevent your program from doing what you expected it to do. With logic errors you get no warning at all. Your code may compile and run but http://www.bouraspage.com/repository/algorithmic-thinking/what-is-the-difference-between-syntax-errors-and-logic-errors the result is not the expected one. Logic errors are the most difficult errors to detect. You must revisit your program thoroughly to determine where your error is. For example, consider a program that prompts the user to enter three numbers, and then calculates and displays their average value. The programmer, however, made a typographical error; one of his or her statements divides the sum of the three numbers by 5, and not by 3 as it should. Of course the program is executed as usual, without any error messages, prompting the user to enter three numbers and displaying a result, but obviously not the correct one! It is the programmer who has to find and correct the erroneously written statement, not the computer or the compiler!

Logical Error - Occurs when there is a fallacy of reasoning. i.e. In python, typing if x < 0 and x > 5. Since a value can't be less than 0 and greater than 5, a logical error will occur. Answer: a) Syntax Error Definition : An error cause by violation of the programming language used. Symptoms : Code fails to compile (error message from compiler) b) Logical Error Definition : An error caused by violation of logic (range, comparison, etc.). This error will NOT crash the program. Symptoms : Unexpected output c) Runtime Error/Execution Error Definition : Any error, normally logical error that cause the program to crash. Symptoms : Program crashes. Answer:
