在C ++中int和long之间有什么区别？
问题描述：
如果我错了，请更正我。
Correct me if I am wrong,
int是4个字节，值范围从-2,147,483,648到2,147,483,647（2 ^ 31）
long是4个字节，值范围从-2,147,483,648到2,147,483,647（2 ^ 31）
int is 4 bytes, with a range of values from -2,147,483,648 to 2,147,483,647 (2^31)
long is 4 bytes, with a range of values from -2,147,483,648 to 2,147,483,647 (2^31)
C ++有什么区别？它们是否可以互换使用？
What is the difference in C++? Can they be used interchangeably?
答
例如，在Windows下，它们是相同的，但是例如在Alpha系统上，long是64位，而int是32位。本文章涵盖了在可变平台上的Intel C ++编译器的规则。总结：
For example, under Windows they are the same, but for example on Alpha systems a long was 64 bits whereas an int was 32 bits. This article covers the rules for the Intel C++ compiler on variable platforms. To summarize:
OS arch size
Windows IA-32 4 bytes
Windows Intel 64 4 bytes
Windows IA-64 4 bytes
Linux IA-32 4 bytes
Linux Intel 64 8 bytes
Linux IA-64 8 bytes
Mac OS X IA-32 4 bytes
Mac OS X Intel 64 8 bytes
