sizeof运算符的依赖关系 [英] dependency of sizeof operator
问题描述
sizeof（int）的输出会有所不同。但是它依赖于什么。可以请任何人
帮助我找出它是依赖于编译器还是操作系统
依赖？
Output of sizeof(int) varies.But on what it depends.Can anybody please
help me to find out if it is compiler dependent or operating system
dependent?
推荐答案
这取决于您使用的机器和编译器。例如，如果你使用turboC / C ++来获得sizeof（int）你获得2但是在相同的
机器上如果你使用gcc或MS Visual studio sizeof（int）= 4。
It depends on the machine you are using and the compiler also. e.g if
you use turboC/C++ to get sizeof (int) you get 2 but on the same
machine if you use gcc or MS Visual studio sizeof(int)=4 .

这取决于C的实现;粗略地说，在
编译器上。但是C实现经常受到操作系统和CPU架构的强烈影响
。

It depends on the C implementation; roughly speaking, on the
compiler. But the C implementation is often strongly influenced
by the operating system and the CPU architecture.

int应与寄存器的大小相同。然而，一些邪恶的人已经在64位计算机上实现了32位整数。所以这取决于编译器
作家。

int should be the same size as a register. However some wicked people have
implemented 32 bit ints on 64-bit machines. So it is up to the compiler
writer.
