char ZEROARRAY[1024] = {0}; 如果一个数组被部分初始化,未初始化的元素将收到相关数据类型的值 0。编译器将用 0 填充未写入的元素。 如果没有指定初始化器,那么具有静态存储的对象将初始化为 0,声明如下。 static int myArray[10]; 如果初始化列表为空或者在初始化列表中指定了 0,数组将被初始化为 0
3、你还可以用memset函数在程序开始时初始化数组。这条命令这在你已经修改了数组之后又想将它重置为全0特别有用。（变长数组适用）头文件：#include <string.h>int arr[1024];arr[5] = 67;memset(ZEROARRAY, 0, 1024); //This will reinitialize all to ZEROint a[10]={0};这样就可以了
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 implicitly the same as objects that have static storage duration. ...
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 described by the designator. int n5 = {4=5,0=1,2,3,4} // holds 1,2,3,4,5 int aMAX...
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...
Suppose the starting address of mark[0] is 2120d. Then, the address of the mark[1] will be 2124d. Similarly, the address of mark[2] will be 2128d and so on. This is because the size of an int address is 4 bytes. Discover The C Initialize Array ...

Objective C类方法load和initialize的区别 过去两个星期里,为了完成一个工作,接触到了NSObject中非常特别的两个类方法(Class Method)。它们的特别之处,在于iOS会在运行期提前并且自动调用这两个方法,而且很多对于类方法的规则(比如继承,类别(Category)
