如果2D数组具有自动存储持续时间，则可以使用数组初始化器列表将所有成员设置为零。
我需要用一个100个元素填充一个数组,所有的元素都应该是零。这是我的阵列:int a[arraysize]; 我知道我应该使用for循环,但是我不知道在代码中把for循环放在哪里。如果我把它放在主要的地方,它也不起作用。因为一个单独的函数正在使用数组。数组没有在主目录中使用。 浏览8提问于2017-01-06得票数 0 回答已采...
正常情况下,struct的成员变量的初始化将在其构造函数内进行{ { name[0] = '\0'; char name[10];但是我如何将2d数组初始化为0或空值呢?my2dDimension[0][0] = { 0 }; //shows error:expected an expression int my2dDimension[20][ 浏览0提问于2013-03-18得票数 0 1回答 D中的结构需要零初始化...

As I wrote earlier, array A is extremely large - much too large for static allocation on Windows. If I compile with IFORT, the compiler correctly complains: catastrophic error: Variable YENI_2D$A too large for NTCOFF. Bigger than 2GB. Use heap instead (Annoyingly, this error appears only...

int array[10]; memset(array,1,10);//或者memset(array,1,sizeof(array)),都是不对的! 【解释】 之前⼀直不明⽩为什么memset这个函数的头⽂件是 "string.h",看完下⾯的内容,你就会明⽩了。 memset函数使⽤说明中提到的是按照byte来填充。 举例来说 char arr[10]; memset(arr,'a',10);...
Hello everybdy, I am a little confused for the following reason: In my code I used a simple for-loop in order to initialize a 2D-array of floats to zero. Because of efficiency reasons, I changed it to use memset and I get totally different results.. How
