包括push_back()的复杂度也居然是 Unspecified; Generally amortized constant, but up to linear in the new string length. 未指定,通常是常数最坏是线性。 什么鬼! 在那题中,因为添加的所有东西都一样,所以可以用std::string::append,这玩意儿的复杂度也是线性。 所以遇到什么对复杂度有要求的还是去用char*...

tbbmalloc's operator new and operator new[] overloads in src/tbbmalloc/proxy.cpp go straight to throwing std::bad_alloc if scalable_msize(sz) returns NULL. I have installed a new_handler using std::set_new_handler(handler), and I expect this handler to be called in...

#定义区域(R) (PI*new_r*new_r) #定义周长(R) (2*PI*new_r) 在公式中使用r代替new_r是合乎逻辑的。而且,new_r是一个指针,因此它不会给出预期的输出。 const r= 0;cin >> r; --这是错误消息背后的原因!--我们在声明变量时使用const来定义在任何情况下都不应该更改变量的赋值。const int r =...
