C++，将一维数组转换为二维数组

#include <iostream>

int main() {
    int oneDimensionalArray[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    int rows = 2;
    int columns = 5;

    int twoDimensionalArray[rows][columns];

    int index = 0;
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < columns; j++) {
            twoDimensionalArray[i][j] = oneDimensionalArray[index];
            index++;
        }
    }

    // 访问二维数组的元素
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < columns; j++) {
            std::cout << twoDimensionalArray[i][j] << " ";
        }
        std::cout << std::endl;
    }

    return 0;
}
