内存的地址的一点思考

int n1;
int n2;
int n3;

printf("n1 address is %p\n",&n1);
printf("n2 address is %p\n",&n2);
printf("n3 address is %p\n",&n3);

 

n1 address is 0xbffdd468
n2 address is 0xbffdd464
n3 address is 0xbffdd460

 

 

定义了3个整形变量

地址分别是0xbffdd460、0xbffdd464、0xbffdd468

一个int变量占4个字节

当时我纳闷的是这个地址是bit还是byte

后面看到一篇文章：字节是最小的内存寻址单位
