/* The <assert.h> header contains a macro called "assert" that allows
|
|
* programmers to put assertions in the code. These assertions can be verified
|
|
* at run time. If an assertion fails, an error message is printed and the
|
|
* program aborts.
|
|
* Assertion checking can be disabled by adding the statement
|
|
*
|
|
* #define NDEBUG
|
|
*
|
|
* to the program before the
|
|
*
|
|
* #include <assert.h>
|
|
*
|
|
* statement.
