在 Pascal 语言中，sizeof() 是一种内存容量度量函数，功能是返回一个变量或者类型的大小（以字节为单位）；在 C 语言中，sizeof() 是一个判断数据类型或者表达式长度的运算符。1、Pascal中的用法：如果longint改为Integer，也输出（Pascal中longInt和Integer都是4字节）；2、C语言中用法：判断数据类型长度符的关键字 sizeof (类型说明符)sizeof 表达式
sizeof(类型说明符,数组名或表达式); 或 sizeof 变量名 1. 定义: sizeof是C/C++中的一个操作符(operator)是也,简单的说其作用就是返回一个对象或者类型所占的内存字节数。 MSDN上的解释为: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including ...
