The FileSize field inserts the size of the document, in bytes, using information from theGeneraltab in thePropertiesdialog box. To view thePropertiesdialog box, click theFile tab, clickInfo, clickProperties(below the document preview on the right side), and then clickAdvanced Properties. Syntax ...
then 32M or 40M aren’t enough. The internal architecture of PHP is not yet fully adapted to 64-bit systems, so it would be entirely memory-saving. In addition, the pointer in C code are actually twice as large, so executable code in memory and generated structures also need more space...
// For example, in 64-bit architecture, the word size is 64 bit (8 bytes), address size is 64 // bit then our integer should be 64 bit. //字符串 // Strings are a series of uint8 types. // A string is a two word data structure: first word represents a pointer to a backing ...
cout<<(sizeof(short) == sizeof(WORD))<<endl; // 相等,输出1 cout<<(sizeof(long) == sizeof(DWORD))<<endl; // 相等,输出1 结论:自定义类型的sizeof取值等同于它的类型原形。 (3)函数类型 考虑下面的问题: int f1(){return 0;}; double f2(){return 0.0;} void f3(){} cout<<sizeof...
这种情况下sizeof的计算同样无意义所以用数组做参数而且需要遍历的时候函数应该有一个参数来说明数组的大小而数组的大小在数组定义的作用域内通过sizeof求值 C++ sizeof 使用规则及陷阱分析 1、什么是 sizeof 、 首先看一下 sizeof 在 msdn 上的定义: The sizeof keyword gives the amount of storage, in bytes...
1、什么是sizeof 首先看一下sizeof在msdn上的定义: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of type size_t. 看到return这个字眼,是不是想到了函数?错了,sizeof不是一个函数,你见过...
sizeof用法 sizeof用法 用法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),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: Thesizeofkeyword gives the amount of storage,inbytes, associated with a variable or a type...
