the error. Logical errors -- Errors that indicate what does assembler do when it detects a syntax error? the logic used when coding the program failed to solve the problem. You do not get error messages with logic errors. Your only clue to the existence of logic errors is the production of wrong solutions.

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 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 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 syntax error definition get error messages 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 http://www.wiley.com/college/busin/icmis/oakman/outline/chap05/slides/errors.htm doing what you expected it to do. With logic errors you get no warning at all. Your code may compile and run but 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 http://www.bouraspage.com/repository/algorithmic-thinking/what-is-the-difference-between-syntax-errors-and-logic-errors 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!

unintended or undesired output or other behavior, although it may not immediately be recognized as such. Logic errors occur in both compiled and interpreted languages. Unlike a program https://en.wikipedia.org/wiki/Logic_error with a syntax error, a program with a logic error is a valid program in the language, though it does not behave as intended. The only clue to the existence of logic errors http://www.answers.com/Q/What_is_the_difference_between_a_Syntax_Error_a_Logic_Error_and_an_Execution_Error_in_a_program's_code is the production of wrong solutions. Debugging logic errors[edit] One of the ways to find these type of errors is to output the program's variables to a file or on the screen in order syntax error to define the error's location in code. Although this will not work in all cases, for example when calling the wrong subroutine, it is the easiest way to find the problem if the program uses the incorrect results of a bad mathematical calculation. Examples[edit] This example function in C to calculate the average of two numbers contains a logic error. It is missing parentheses in the calculation, and logical error so it compiles and runs but does not give the expected answer due to operator precedence (division is evaluated before addition). int average(int a, int b) { return a + b / 2; /* should be (a + b) / 2 */ } See also[edit] Software Testing portal Syntax error Off-by-one error This computer-programming-related article is a stub.

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:
