Problem Statement

Assertions are a way of breaking out of code when there is an error or an unexpected input. Some languages throw exceptions and some treat it as a break point.

Show an assertion in your language by asserting that an integer variable is equal to 42.

Let's start with the solution:

// test if 'a' is 42, and if not stop the execution of the code and print 
// some error message
if (a != 42)
{
  stop("a is not 42 as expected, therefore I stop until this issue is resolved!");
}
