我有四个uint8_t数组：
uint8_t arrayOne[12] = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x01,0xC1,0x00,0x01 };
uint8_t arrayTwo[12] = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x4E,0x2D,0x00,0x0C };
uint8_t arrayThree[12] = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x01,0xF3,0x00,0x01 };
uint8_t arrayFour[12] = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x20,0x04,0x00,0x01 };
我希望他们添加到另一个数组：
uint8_t theArray[4][12] = { arrayOne,arrayTwo,arrayThree,arrayFour };
但是当我将它们添加到theArray时，数组的值会发生变化。
为什么吗 我怎样才能正确地将它们添加到数组中？
答案 0 :(得分：4)
toplevel数组应该只是一个指针数组：
uint8_t *theArrays[] = { arrayOne,arrayTwo,arrayThree,arrayFour };
您将丢失有关每个“行”长度的信息，但这很好。
我认为您不能像在示例中那样在初始值设定项中引用数组，并且会自动将元素复制到更大的数组中。
答案 1 :(得分：3)
您必须使用标头memcpy中声明的标准函数<string.h>复制结果数组中的每个数组。例如
#include <string.h>
#include <stdint.h>
//...
uint8_t * arrayPtrs[] = { arrayOne, arrayTwo, arrayThree, arrayFour };
for ( size_t i = 0; i < sizeof( theArray ) / sizeof( *theArray ); i++ )
{
memcpy( theArray[i], arrayPtrs[i], sizeof( theArray[i] ) );
}
答案 2 :(得分：1)
您正尝试使用指向uint8_t 的指针初始化 uint8_t数组，而不是 uint8_t 元素。
试试这个：
