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...
This tutorial introduces how to initialize an array to0in C. ADVERTISEMENT The declaration of an array in C is as given below. charZEROARRAY[1024]; It becomes all zeros at runtime at the global scope. There is a shorthand method if it is a local array. The declaration and initialization...

int a[10]={0};另一种 是memset 在头文件string.h里int a[10];memset（a，0，sizeof（a））；最简单的方法就是用一个循环吧数组所有元素设置为0：int arr[100];int i = 0;for(i = 0 ; i < 100 ; i++)arr[i] = 0; //This will make all ZERO我们还可以利用其他几种方式...
视频游戏、社交网络和你的活动手环有什么共同点?它们运行在一群(或多或少)程序员在很远很远的地方编写的软件上。在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。
