The presence of logical errors leads to undesired or incorrect output and are caused due to error in the logic applied in the program to produce the desired output.Also, logical errors could not be detected by the compiler, and thus, programmers has to check the entire coding of a c program line by line. This can … Consider following C statement: This ability of the program is known as robustness and the code used to make a program robust is known as guard code as it guards program from terminating abruptly due to occurrence of execution errors. Examples of some illegal operations that may produce runtime errors are: It should be noted that occurrence of these errors may stop program execution, thus to encounter this, a program should be written such that it is able to handle such unexpected errors and rather than terminating unexpectedly, it should be able to continue operating. Argument to moderation (false compromise, middle ground, fallacy of the mean, argumentum ad temperantiam) – assuming that a compromise between two positions is always correct.

They are the first line of defense against logic errors, so if anything you want to see MORE warnings so that you can fix them before they become harder-to-diagnose runtime problems. This kind of errors are occurred, when it violates the rule of C++ writing techniques or syntaxes. 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). Because this can not calculate the average value of a and b correctly. Logic errors are ones where you don't get the result you were expecting.
