生成唯一编号

我 INT32 数据类型的三个变量在C ++中。我想生成 C ++ 三 INT32 数字组合的唯一编号。比如我有 INT iVal1 ， INT iVal2 和 INT iVal3 。是否有任何的算法来做到这一点？

I have three variables of int32 data type in C++. I want to generate unique number for combination of three int32 numbers in C++. For example I have int iVal1, int iVal2, and int iVal3. Is there any algorithm to do this?

为了避免混乱的问题我会重组的问题。基本上我想生成三个整数一个唯一的编号，因为我要保存这个数字在地图一键检索数据。

In order to avoid confusion in question I will rephrase the question. Basically I want to generate a unique number with three integers because I want to store this number as a key in map to retrieve the data.

有什么建议？谢谢你。
