These can also be called type errors.When your code compiles and your program runs as planned, but the output is incorrect, you have a logic error. Example: A semantic error would compile, but be incorrect logically: const int pi = 12345; Your program will likely compile and run without error but your results will be incorrect. (Note Commands are actions that are performed on the subject of the statement, with additional descriptions and branching commands added to the structure in the form of operands such as AND, OR He is the author of Baldwin's Programming Tutorials, which have gained a worldwide following among experienced and aspiring programmers.

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 to define the Examples[edit] This example function in C to calculate the average of two numbers contains a logic error. Usually the program runs successfully. He has also published articles in JavaPro magazine.

For example, writing [math]n3=n1/n2+n3[/math] when really you wanted to divide [math]n1[/math] by [math]n2+n3[/math] -- the compiler has no way to tell that you intended to divide instead of multiplying; you told This could be something as simple as a typo, but can be  anything that breaks the language "grammar", such as using a type  that has not yet been defined Any value divided by 0 produces an infinitely large result, which is too large to be accommodated by the computer. The only clue to the existence of logic errors is the production of wrong solutions.

Can cause the program to halt, causing a runtime error.   A runtime error is an error detected whilst a program is executing. Result of dividing by zero.
