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 o
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 ...

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 ...

请使用 traits classes 表现类型信息(traits classes 通过 templates 和“templates 特化” 使得 “类型相关信息” 在编译期可用,通过重载技术(overloading)实现在编译期对类型执行 if…else 测试) 认识template 元编程(模板元编程(TMP,template metaprogramming)可将工作由运行期移往编译期,因此得以实现早期错误侦测和更...
We may find this discomforting because we are not used to overloading operands. Pointer to void A pointer to void is a general-purpose pointer used to hold references to any data type. An example of a pointer to void is shown below: void *pv; It has two interesting properties: A ...
