本文介绍了海湾合作委员会警告：标量初始化牙套的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有查询表如下定义，我利用GCC的。当我编译我得到警告视为
警告：标量初始化牙套
这是什么意思的警告？我应该如何初始化该LUT？我在初始化此结构犯了一个错误？
帮助！

解决方案
您应该删除括号： {和} 围绕单个值。

将给予警告。
I have look-up-table as defined below and I'm making use of GCC. When I compile I get warnings as
warning: braces around scalar initializer
What does this warning mean? How should I initialize this LUT? Am I making a mistake in initializing this structures?

You should remove the braces: { and } around single values.
