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。
所以一般memset只能用来填充char型数组，（因为只有char型占一个字节）如果填充int型数组，除了0和-1，其...
EN二维数组和指针⑴ 用指针表示二维数组元素。 要用指针处理二维数组，首先要解决从存储的角度对二维数组...
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
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...
matrix(N * N, std::numeric_limits<float>::max());事实上，你甚至可以很容易地将它变成一个2D...
The C standard library doesn't provide functions to set each element of an array to a specified value, other than memset. You'll just have to write a loop (untested code follows): > int v[1000000]; size_t i; for (i = 0; i < sizeof v / sizeof v[0]; i ++) { v[i] = ...
#include<string.h> void *memset(void *s, int c, size_t n); 【使⽤说明】 The memset() function fills the first n bytes of the memory area pointed to by s with the constant byte c. 【错误⽤法】 int array[10]; memset(array,1,10);//或者memset(array,1,sizeof(array)),都是...
