What’s difference between runtime error and logical error?

The main difference between execution error and logical error is that a runtime error is an error that occurs due to an illegal operation in the program while a logical error is an error that occurs due to a failure in the program. program algorithm.

Runtime error and logical error are two types of errors. An error is an unexpected result of a program. Errors can affect the correct execution of the program. Therefore, it is important to fix the errors. Apart from these two types of error, there is another type of error called a syntax error, which occurs due to errors in the syntax of the program.

What is a runtime error

A runtime error is an error that occurs at runtime. In other words, the computer detects these errors when it runs the program. This will cause the program to stop or crash. A diagnostic message will be displayed on the screen.

Also, a runtime error occurs due to an illegal operation in the program. For example, dividing a number by zero will give a runtime error. Also, accessing a memory location that is not available is also a runtime error.

What is a logical error

An algorithm is a sequence of steps to follow when writing a program. Logic errors occur due to a problem in the algorithm. These errors will not cause the program to terminate execution. Instead it will give an incorrect output. The programmer has to read and check each statement to identify a logical error. Therefore, it is a difficult task. For example, if the programmer uses subtraction (-) instead of addition (+), it will give incorrect output. This type of error is a logical error.

Difference Between Runtime Error and Logic Error

Definition

A runtime error is an error that occurs when a computer program is executed, while a logical error is an error in a program that causes it to function incorrectly, but not terminate abnormally.

Because

Further describing the above, the runtime error occurs due to an illegal operation in the program, while the logical error occurs due to a problem in the algorithm.

Detection

Also, another difference between runtime error and logical error is that computers detect runtime errors at the time of executing the program. On the other hand, the programmer must check each statement in the program to determine the logical error.

Exit

The further difference between runtime error and logic error is that runtime errors cause the program to stop executing or crash. However, logical errors do not cause the program to stop executing, but it will give incorrect output.

examples

Runtime errors can occur due to reasons such as dividing a number by zero or accessing a memory location that is not available. In contrast, logic errors can occur due to incorrect use of operators and improper sequence of instructions. This is another difference between runtime error and logical error.

conclusion

The main difference between runtime error and logical error is that a runtime error is an error that occurs due to an illegal operation in the program while a logical error is an error that occurs due to a flaw in the program’s algorithm.
