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 other words, it can be used to add diagnostics in your C program. Assertions are mainly used to check logically impossible situations. For example, they can be used to check the state a code expects before it starts running or state after it finishes running. Unlike normal error handling, assertions are generally disabled at run-time. Assertion failed: expression, file filename, line line number This macro is disabled if, at the moment of including , a macro with the name NDEBUG has already been defined.

In this example, assert is used to abort the program execution if print_number is called with a null pointer as attribute. This happens on the second call to the function, which triggers an assertion failure to signal the bug.

Following is the declaration for assert () Macro. Parameters. If expression evaluates to TRUE, assert () does nothing.

It checks the value of an expression that we expect to be true under normal circumstances. If expression is a nonzero value, the assert macro does nothing. An assertion is a specification that verifies that a program satisfies certain conditions at particular points, during its execution (run-time condition checks).
