size_t 是变量名,size_type是类型名，就像int 一样，它是用typedef 定义的 capacity的意思是容量，此方法返回的是该vector对象最多能容纳多少个元素。size的意思是大小，此方法是返回该vector对象当前有多少个元素。都是对内置类型的封装。根据内部实现，可能是一样，也可能不一样,可能是unsigned long之...

关于:size_t和size_type(转抄) 为了使自己的程序有很好的移植性,C++程序员应该尽量使用size_t和size_type,而不是int,unsigned。 在标准C/C++的语法中,只有int float char bool等基本的数据类型,至于size_t,或size_type都是以后的编程人员为了方便记忆所定义的一些便于理解的由基本数据类型的变体类型。 size_t...

The types size_t and ptrdiff_t were created to perform correctaddress arithmetic. It had been assumed for a long time that the size of int coincides with the size of a computer word (microprocessor's capacity) and it can be used as indexes to store sizes of objects or pointers. Correspon...
什么叫做物体的体积?体积:读音tǐjī,英文名[volume;size;capacity]是指物质或物体所占空间的大小;占据一特定容积的物质的量 示例1;木箱的体积为3立方米2;电解水时放出二体积的氢与一体积的氧 常用的体积单位:立方米、立方分米、立方厘米. 体积的常用计算(v=体积;a=长;b=宽;h=高;s=面积) 长方体的体积=...
