Declaration: void assert (int expression); The C library macro void assert(int expression) allows diagnostic information to be written to the standard error file. In other words, it can be used to add diagnostics in your C program. Declaration. Following is the declaration for assert() Macro. void assert(int expression); Parameters.

If NDEBUG is defined as a macro name at the point in the source file where is included, the assert macro is defined simply as: #define assert (ignore) ((void)0) The conventional wisdom is to use assert() to help debug your code, to warn you when something "impossible", something that must not happen, has happened. This "warning" takes the form of exiting your program. I've heard Jim Coplien (general C++ guru and SCRUM trainer) advocate leaving your asserts active in deployed code. (It sounds crazy, I know) Understanding assert in C/C++ Using assertions in C programs. 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.

Following is the declaration for assert() Macro. void assert(int expression); Parameters.

If expression evaluates to TRUE, assert () does nothing. If expression evaluates 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 assert( size <= LIMIT ); will abort the program and print an error message like this: Simple and Static Assertion (assert) in C Programming Language 1.

In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution. Precondition Assertion-> Condition satisfied before main body execution; Post-condition Assertion-> Condition satisfied after main body execution; Invariant Assertion-> Condition satisfied after every repetitive region of a function (like a loop) Now that we know what an assertion is, let’s look at doing this in a C program. A Simple assert() Using A Macro. assert() is usually defined in C using a macro (rather than a function), due to the ability of automatically keep track of things such as the filename and line number that the assert() was written on.
