In this video tutorial, lets see how we can make use of #error preprocessor command or directive.

Where Is It Useful? If you’re a Software developer working with C programming language, then your project will have a lot of code and dependency source codes. While compiling, compiler will take a lot of time. In big projects usually you forget the purpose of compilation by the time it completes compilation. In such cases, make use of #error directive. If there are any errors at certain locations the compiler will stop further compilation as and when it encounters #error directive. This saves a lot of time and resources. So #error directive is usually helpful in debugging your project code.

It’s also helpful in projects with critical user inputs. Suppose user enters wrong data due to which the project itself might crash and utilize a lot of resource while trying to execute. In such cases it’s better to terminate the program execution.
