1)For operator overloading to work, at least one of the operandsmust be a user defined class object. 2)Assignment Operator:Compiler automatically creates a default assignment operator with every class. The default assignment operator does assign all members of right side to the left side and wo...
For example, overloading func(const pair<int, int>&) and func(const pair<string, string>&), and calling func() with pair<const char *, const char *> will compile with this change. However, this change breaks code that relied on aggressive pair conversions. Such code can typically be ...
Limited operator overloading to enable userland dynamic arrays Optional pre and post conditions Current status The current stable version of the compiler isversion 0.7.1. The upcoming 0.7.x releases will focus on expanding the standard library, fixing bugs and improving compile time analysis. Follow...

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 ...
虚函数(virtual function)、运算符重载(operator overloading)、多重继承(multiple inheritance)、模板(template)、异常(exception)、RTTI、名字空间(name space)逐渐被加入标准。1998年国际标准组织(ISO)颁布了C++程序设计语言的国际标准ISO/IEC 14882-1998。遗憾的是,由于C++语言过于复杂,以及他经历了长年的演变,直到...

在operator= 中处理 “自我赋值” 赋值对象时应确保复制 “对象内的所有成员变量” 及 “所有 base class 成分”(调用基类复制构造函数) 以对象管理资源(资源在构造函数获得,在析构函数释放,建议使用智能指针,资源取得时机便是初始化时机(Resource Acquisition Is Initialization,RAII)) 在资源管理类中小心 copying 行...
