c之精髓——指针(pointer)——用来存储地址的变量。一般来讲,指针是一个其数值为地址的变量(或更一般地说是一个数据对象)。 一元运算符&可以取得变量的存储地址,一个变量的地址可以被看作是该变量在内存中的位置。 地址运算符&:后跟一个变量名时,&给出

Pointers are basically the same as any other variable. However, what is different about them is that instead of containing actual data, they contain a pointer to the memory location where information can be found. This is a very important concept, and many programs and ideas rely on pointers...
