MISRA C:2023 Rule 16.2
A switch label shall only be used when the most closely-enclosing compound statement is the body of a switch statement
自 R2024a 起
描述
规则定义
A switch label shall only be used when the most closely-enclosing compound statement is the body of a switch statement 1
理由
C 标准允许在 switch 语句体中的任意语句前放置 switch 标签（例如 case 或 default）。这种灵活性可能导致代码非结构化。为了避免代码非结构化，请确保 switch 标签只出现在 switch 语句体的最外层。
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。
