在初始化已知大小的数组时,提供比元素更多的初始化程序是错误的(除了从字符串文字初始化字符数组时)。 A designator causes the following initializer to initialize of the array element described by the designator. Initialization then continues forward in order, beginning with the next element after the one ...
当宣告C/C++的built-in type后,必须马上initialize该变量的值,因为C/C++在宣告变量时,仅为该变量配置了一块内存,却没对该变量设定任何初始值,所以该变量目前的值为宣告该变量前所残留的值,虽可直接使用该变量,但并没有任何意义。 尤其在使用array时,当宣告完array及其大小后,第一件事情就是为array中所有element...
You can initialize an array of characters (or wide characters) with a string literal (or wide string literal). For example: 复制 char code[ ] = "abc"; initializes code as a four-element array of characters. The fourth element is the null character, which terminates all string literals...

string literal used to initialize an array, an expression that has type ‘‘array of type’’ is converted to an expression with type ‘‘pointer to type’’ that points to the initial element of the array object and is not an lvalue. If the array object has register storage class, the...

[6.7.8.21] If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized...
