推荐答案

您不能。这通常与动态内存分配完成的。

You can't. This is normally done with dynamic memory allocation.

// Like "ENEMY enemies[100]", but from the heap
ENEMY* enemies = malloc(100 * sizeof(ENEMY));

// You can index pointers just like arrays.
enemies[0] = CreateEnemy();

// Make the array bigger
enemies = realloc(enemies, 200 * sizeof(ENEMY));

// Clean up when you're done.
free(enemies);
