Are Flexible Array Members Supported in C ?

Flexible Array Members in C

Flexible array members, a feature introduced in C99, allow declaring arrays within structures without specifying a fixed size. However, their validity in C has been a subject of debate.

In C , flexible array members are not supported. This is because the C standard predates the introduction of flexible array members in C and has not been revised to include them.

The syntax struct blah { int foo[]; } used to declare a flexible array member is invalid in C . To work around this, the syntax struct blah { int foo[0]; } can be used. Here, [0] signifies a zero-length array, effectively creating a "flexible" member without the need for explicit support.
