15 de oct. de 2009 · The assert() macro returns TRUE if its parameter evaluates TRUE and takes some kind of action if it evaluates FALSE. Many compilers will abort the program on an assert() that fails; others will throw an exception. One powerful feature of the assert() macro is that the preprocessor collapses it into no code at all if DEBUG is not defined.
In C++, an assertion is a statement used to state or assert that the expression must be true. It is used as a debugging tool to check the conditions that cannot happen unless there is a bug. In this tutorial, you will learn about assertions in C++ with the help of examples.

Asserts are a way of explicitly checking the assumptions that your code makes, which helps you track down lots of bugs by narrowing down what the possible problems could be. They are typically only evaluated in a special "debug" build of your application, so they won't slow down the final release version.
