在韩国政府的一次考试中，(1)是一个正确的陈述.
Choose the wrong statement for the following two-dimensional array in C:
int mat[3][4]={1,2,3,4,5,6};
(1) The value of mat[2][2] is 0.
我一直在想，C不会用0‘S填充整数数组，所以我试着查找规范，但文档太大了.This answer(下面的屏幕截图用于快速查看，全文在链接中)似乎是在说未完成的初始化意味着0，但C规范是否保证了这一点？
来自C标准(6.7.9初始化):
19初始化应按初始化器列表顺序进行，每个 为特定子对象提供的初始值设定项覆盖任何 之前列出的相同子对象的初始值设定项；all subobjects that are not initialized explicitly shall be initialized implicitly the same as objects that have static storage duration.
和
10如果具有自动存储持续时间的对象未初始化 显然，它的值是不确定的.一百:
-如果是指针类型，则初始化为空指针；
— if it has arithmetic type, it is initialized to (positive or unsigned) zero;个
— if it is an aggregate, every member is initialized (recursively) according to these rules, 和 any padding is initialized to zero bits;
— if it is a union, the first named member is initialized (recursively) according to these rules, 和 any padding is initialized to zero bits;
因此，数组mat中未被显式初始化的所有元素都被隐式地用零来初始化.
int mat[3][4]={1,2,3,4,5,6};
因此，在上面的声明中，mat[2][2]等于0.
我通过韩国政府考试了吗？:)
