class S { public: S() = default; private: S(const S&) = default; }; void f(const S&); // pass S by reference int main() { S s; f(s); } 弃用属性化 ATL 代码支持(默认开启等级 1 (/W1)) 以前版本的编译器支持属性化 ATL 代码。 由于下一阶段将删除从Visual Studio 2008 开始的...
最后,main.cpp中定义了主函数,它从argv[]收集命令行参数,将它们转换成一个整数向量,调用sum_integers函数,并将结果打印到输出: 代码语言:javascript 复制 #include "sum_integers.hpp" #include <iostream> #include <string> #include <vector> // we assume all arguments are integers and we sum them up ...

宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...
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 ...
