VS调试时按Alt+8打开汇编窗口                     Alt+7打开堆栈窗口     Alt+6打开内存窗口     Alt+5打开寄存器窗口看每句C对应的汇编、堆栈、内存和寄存器变化

vector 的reserve增加了vector的capacity，但是它的size没有改变！而resize改变了vector的capacity同时也增加了它的size！原因如下：      reserve是容器预留空间，但在空间内不真正创建元素对象，所以在没有添加新的对象之前，不能引用容器内的元素。加入新的元素时，要调用push_back()/insert()函数。     

int main(void){unsigned int a = 0xFFFFFFF7;unsigned char i = (unsigned char)a;char* b = (char*)&a;printf("%08x, %x", i, *b);return 0;}结果 000000F7   FFFFFFF7解析：int 4字节，他在内存中是反着存
