静态初始化数组的语法使用大括号，如下所示:

The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

这将对数组进行零初始化.

This will zero-initialize the array.

对于多维数组，你需要嵌套的花括号，像这样:

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

请注意，Array_size 必须是编译时常量才能使其正常工作.如果 Array_size 在编译时未知，则必须使用动态初始化.(***是 std::vector).

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).
