assert (expression)
Assert is a macro that indicates expression is expected to be true at this point in the program. It causes an exit(2) with a diagnostic comment on the standard output when expression is false (0). Compiling with the cc(1) option −DNDEBUG effectively deletes assert from the program.
’Assertion failed: file f line n.’ F is the source file and n the source line number of the assert statement.
