在 C 语言中，断言被定义为宏的形式（assert (expression)），而不是函数，其原型定义在文件中。. 其中，assert 将通过检查表达式 expression 的值来决定是否需要终止执行程序。. 也就是说，如果表达式 expression 的值为假（即为 0），那么它将首先向标准错误流 stderr 打印一条出错信息，然后再通过调用 abort 函数终止程序运行；否则，assert 无任何作用。. 默认情况下，assert

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.

Previous Page. Next Page. The assert.h header file of the C Standard Library provides a macro called assert which can be used to verify assumptions made by the program and print a diagnostic message if this assumption is false. The defined macro assert refers to another macro NDEBUG which is not a part of .

When using the GNU C compiler, the name of the function which calls assert is taken from the built-in variable __PRETTY_FUNCTION__; with older compilers, the function name and following colon are omitted. 2005-11-13 2007-09-27 In NUnit 3.0, assertions are written primarily using the Assert.That method, which takes constraint objects as an argument.

There is no "going crazy with C_ASSERT" in C++, in the sense of replacing all uses of ASSERT with C_ASSERT. The only "going crazy" is not understanding the difference between compile-time and run-time. assert宏的原型定义在<assert.h>中，其作用是如果它的条件返回错误，则终止程序执行，原型定义：#include <assert.h&;gt;void assert( int expression ); assert的作用是现计算表达式 expression ，如果其值为假（即为0），那么它先向stderr打印一条出错信息，然后通过调用 abort 来终止程序运行。 The macro assert() can diagnose program bugs.
