To achieve pass by reference in C, a pointer to the desired type is passed. This approach is used when passing a variable that can be modified within a function. Therefore, if theint *is intended to be modified and the changes should be visible in the caller, the function should accept ...

断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #defineNDEBUG// 加上这行,则 asser...
