使用memcpy复制C++中的N维数组

void* memcpy(void* destination, const void* source, size_t num);

#include <iostream>
#include <cstring>

int main() {
    const int rows = 3;
    const int cols = 4;

    int sourceArray[rows][cols] = {{1, 2, 3, 4},
                                   {5, 6, 7, 8},
                                   {9, 10, 11, 12}};

    int destinationArray[rows][cols];

    std::memcpy(destinationArray, sourceArray, sizeof(sourceArray));

    // 打印目标数组
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            std::cout << destinationArray[i][j] << " ";
        }
        std::cout << std::endl;
    }

    return 0;
}
