Logic error

What is logic error?
A logical error is an error in the source code of a program that gives way to unforeseen and erroneous behavior. A logic error is classified as a type of runtime error that can cause a program to produce incorrect output. It can also cause the program to crash while running.

Logical errors are not always immediately recognizable. This is because, unlike syntax errors in the language, such errors are valid but do not produce the intended behavior. These can occur in both interpreted and compiled languages. A logical error is also known as a logical error.

Logic errors cause a program to not work properly. For example, if 'if ($ i = 1) {…}' is entered incorrectly in PHP and not 'if ($ i == 1) {….}', The former means 'will', while the latter means 'corresponds.' The wrong if statement would always return TRUE if 1 is assigned to the variable $ i. In the correct version, however, the instruction only returns TRUE if the value of the variable $ i is equal to 1. The wrong case syntax is perfectly correct in every language. So the code would compile successfully without producing any syntax errors. However, while the code is running, the resulting output may be incorrect, indicating that a certain logical error has occurred. Logic errors tend to be hidden in the source code and can usually be more difficult to detect and debug.
