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...
简介: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...

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...
// wordSize代表是一个word里包含多少字节 // 64bit: 8 bytes // 32bit: 4 bytes // The word size is the number of bytes in a word, which matches our address size. // For example, in 64-bit architecture, the word size is 64 bit (8 bytes), address size is 64 ...

malloc(sizeof(int)*100); which will return a pointer to a block of memory big enough to hold 100 ints. Is there any equivalent in fortran? Use case: I have a binary file which is opened as: open(unit=10,file='foo.dat',access='stream',form='unformatted',status='old') ...
