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

#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...
C guarantees that any integer type with a value of all bits 0 has the value 0. This is not guaranteed for floating point types or pointers. > As to how to do it, you need to use a loop: > #define ARRAY_SIZE 1000000 > int v [ARRAY_SIZE];...
在Win32应用程序接口编程中,通常使用带有多个字段的Cstruct。通常只有几个参数具有有意义的值,而其他所有参数都必须清零。这可以通过以下两种方式中的任何一种实现:memset( &theStruct, 0, sizeof( STRUCT ) );STRUCT theStruct= {}; 第二个变体看起来更干净-它是一行程序,它没有任何可能被错误输入的参数,从而...
