intabs(inti);longintlabs(longintli);floatfabsf(floatf);doublefabs(doubled);longdoublefabsl(longdoubleld); 函数fabsf和fabsl不属于早期C标准,却存在于修订后的C9X标准中。 标准C库还有一个“put”函数组: intfputc(intc, FILE *f);intfputs(charconst*s, FILE *f);intputchar(intc);intputs(charcon...
1. **方法名必须相同**(对应选项C)。这是重载的基础,只有方法名相同才可能构成重载。2. **参数列表必须不同**(对应选项E)。参数不同可以是参数类型、顺序或数量的不同,这是区分不同重载方法的唯一依据。3. **必须定义在同一类或同一个作用域中**(选项B描述不严谨,未明确体现此条件)。错误选项分析:- *...

说明:本文重点是掌握输出操作符重载的代码写法。文章中的解耦(又称解耦合)和模块化概念属于选读理解的概念,不需要初学者掌握。 输出对象 当类对象有多个成员变量的时候,输出这些变量往往比较麻烦。比如: Studentstu("001","张三",18,"1990-02-12");std::cout<<stu.m_id<<" "<<stu.m_name<<" "<<stu....
