MISRA C:2023 Rule 9.5
Where designated initializers are used to initialize an array object the size of the array shall be specified explicitly
自 R2024a 起
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。
