runtime error that may simply produce the wrong output or may cause a program to crash while running. Many different types of programming logic error meaning mistakes can cause logic errors. For example, assigning a value to the

also produce unwanted results. Even small typos that do not produce syntax errors may cause logic errors. In the PHP code example below, the if statement may cause a logic error

since the single equal sign (=) should be a double equal sign (==). Incorrect: if ($i=1) { ... } Correct: if ($i==1) { ... } In PHP, "==" means "is equal to," while "=" means "becomes." Therefore, the incorrect if statement always returns TRUE, since assigning 1 to the variable $i returns a TRUE value. In the correct code, the if statement only syntax error returns TRUE if $i is equal to 1. However, since the syntax of the incorrect code is acceptable, it will not produce a syntax error and the code will compile successfully. The logic error might only be noticed during runtime. Because logic errors are often hidden in the source code, they are typically harder to find and debug than syntax errors.

unintended or undesired output or other behavior, although it may not immediately be recognized as such. Logic errors occur in both compiled definition logic philosophy and interpreted languages. Unlike a program with a syntax error, a program definition of logic in math with a logic error is a valid program in the language, though it does not behave as intended. definition of logic in literature The only clue to the existence of logic errors is the production of wrong solutions. Debugging logic errors[edit] One of the ways to find these type of errors is to http://techterms.com/definition/logic_error output the program's variables to a file or on the screen in order 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 https://en.wikipedia.org/wiki/Logic_error C to calculate the average of two numbers contains a logic error. It is missing parentheses in the calculation, 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.

Know Your Bugs: Three Kinds of Programming Errors Visual Studio 2008 Other Versions Visual Studio 2005 In this lesson, you will learn about the different types of errors that can occur when writing a program.Even the most experienced programmers make mistakes, and knowing how to debug an application and find those mistakes is an important part of programming. Before you learn about the debugging process, however, it helps to know the types of bugs that you will need to find and fix.Programming errors fall into three categories: compilation errors, run-time errors, and logic errors. The techniques for debugging each of these are covered in the next three lessons.Compilation Err
