intmain（void）｛ intarr［1024］＝｛0｝；／／ThiswillmakeallZERO ／／statements ｝ 3、可以用memset函数在程序开始时初始化数组。这条命令这在已经修改了数组之后又想将它重置为全0特别有用。intarr［1024］；arr［5］＝67；memset（ZEROARRAY，0，1024）；／／ThiswillreinitializealltoZERO ...
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...
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)
+(void)load和+(void)initialize可当做普通类方法(Class Method)被调用 接着, 在程序中让ChildClass直接调用load: [ChildClass load]; 程序正常运行,并输出了结果: SuperClass +[SuperClass initialize] SuperClass +[SuperClass load] +[Insideinitialize load] ...
