ordered_map['key1']='value1'# 添加键'key1'和对应值'value1'ordered_map['key2']='value2'# 添加第二个键'key2'和对应值'value2' 1. 2. 解释: 我们给ordered_map添加了两个键值对,注意插入顺序是保留的。 步骤4: 打印有序 Map 我们可以简单地打印这个有序字典,以查看其内容: print(ordered_map...
This removes potential name conficts for some field names. 0.5.2 also introduces the long awaited clone operation for tables and vectors. A C++ smoketest was added to reduce the number void pointer assignment errors that kept sneaking in. The runtime library now needs an extra filerefmap.c....
This bug caused inconsistencies in aggregate initialization and member initialization order. The generated initialization code is now correct. However, this change can lead to errors or warnings in source that inadvertently relied on the mis-ordered members, as in this example:...
