assert() is implemented as a macro; if the expression tested has side-effects, program behavior will be different depending on whether NDEBUG is defined. This may create Heisenbugs which go away when debugging is turned on. See Also abort(3), assert_perror(3), exit(3) Referenced By al_assert(3), expackf(3), register_assert_handler(3), trace(3)
assert in C Assert is a macro that is used to check specific conditions at runtime (when a program is under execution) and is very useful while debugging a program. To use it, you must include the header file "assert.h" in the program. Declaration: void assert (int expression); In C, assertions are implemented with the standard assert macro. The argument to assert must be true when the macro is executed, otherwise the program aborts and prints an error message. For example, the assertion The C_ASSERT macro is defined as follows. #define C_ASSERT(e) typedef char __C_ASSERT__[(e)?1:-1] The following examples demonstrate common types of compile-time assertions. The assert.h header file of the C Standard Library provides a macro called assert which can be used to verify assumptions made by the program and print a diagnostic message if this assumption is false. The defined macro assert refers to another macro NDEBUG which is not a part of
assert will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. It's commonly used during debugging to make the program fail more obviously if an unexpected condition occurs.
The following articles provides an outline on Assert in C#. Assert method is one of the most effective method to detect logic errors at runtime and making it easy to correct the error at production level. An assert method generally takes 2 arguments: one is a boolean expression and another is a message to be displayed. Assertions in C/C++ Assertions are statements used to test assumptions made by programmer. For example, we may use assertion to check if pointer returned by malloc () is NULL or not. Following is syntax for assertion.
