int *array; array = (int *)malloc(sizeof(int) * length); 之后使用realloc为其追加内存.c里面的数组都是定长的,没有变长的数组!所谓的柔性数组依然要用malloc分配内存~还是定长的你可以自己写个vector~很简单,就是一个链表~只要int array[n];就行。记得编译器得支持C99并开启,

However, explicit operator bool() forbids implicit conversions to bool, so you can't say bool b = sp; and given a bool return type, you can't say return sp. Now that real variadic templates are implemented, _VARIADIC_MAX and related macros have no effect. If you're still defining _...

The -static GCC option related to static linking forbids all dynamic linking. Instead, use the -Wl,-Bstatic and -Wl,-Bdynamic options to control linker behavior more precisely. See Section 2.2.6, “Using both static and dynamic libraries with GCC”. 2.2.5. Using a...
