An assert method generally takes 2 arguments: one is a boolean expression and another is a message to be displayed. A C macro to provide compile time assertions This macro can help programmers find bugs in their programs, or handle exceptional cases via a crash that will produce limited debugging output. If expression is false (i.e., compares equal to zero), assert () prints an error message to standard error and terminates the program by calling abort (3). Explanation A static assert declaration may appear at namespace and block scope (as a block declaration) and inside a class body (as a member declaration). If bool_constexpr returns true, this declaration has no effect. Otherwise a compile-time error is issued, and the text of message, if any, is included in the diagnostic message.

In the C Programming Language, assert is a macro that is designed to be used like a function. It checks the value of an expression that we expect to be true under normal circumstances.

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 …

If expression evaluates 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.

Assert c

The purpose of assert.h is to test assumptions. In C there are a few frameworks to test code, but those frameworks aren't as easy as for example JUnit in Java.

Assert c

The defined macro assert refers to another macro NDEBUG which is not a part of . The expression assert(E) is guaranteed to be a constant subexpression, if either NDEBUG is defined at the point where assert is last defined or redefined (i.e., where the header or was last included); or E, contextually converted to bool, is a constant subexpression that evaluates to true. (since C++17) An assert is a statement in C++ which tests for a condition like the one explained above. If the condition is true, the program continues normally and if the condition is false, the program is terminated and an error message is displayed. We can provide an assertion using an assert preprocessor macro.

In C, we use the assert macro to define an assertion statement. This is there in the An example – Using assert in a loop. Consider the below code, that simply adds integers within a given range.

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.
