MISRA C++:2023 Rule 6.0.2
When an array with external linkage is declared, its size should be explicitly specified
自 R2024b 起
描述
规则定义
When an array with external linkage is declared, its size should be explicitly specified. 1
理由
虽然您可以先声明一个不完整的数组类型,之后再完善该类型,但在首次声明时指定数组大小可以使后续的数组访问更不易出错。
Polyspace 实现
如果声明外部数组时未指定大小,则 Polyspace® 会报告违反了此规则。
故障排除
如果您预期会出现违规,而 Polyspace 未报告该违规,请参阅诊断为何编码规范违规未按预期显示。
