MISRA C:2012 Rule 9.5
Where designated initializers are used to initialize an array object the size of the array shall be specified explicitly
描述
规则定义
Where designated initializers are used to initialize an array object the size of the array shall be specified explicitly 1 .
理由
如果数组大小没有显式指定,则它由已初始化元素的最大索引确定。当使用较长的指定初始化函数时,可能无法立即看出哪个元素的索引最大。
故障排除
如果您预期会出现违规,但未看到该违规,请参阅诊断为何编码规范违规未按预期显示。
