C++中使用指针转置矩阵

#include <iostream>

void transposeMatrix(int* matrix, int rows, int cols) {
    int* transposedMatrix = new int[rows * cols];

    // 使用指针进行矩阵转置
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            transposedMatrix[j * rows + i] = matrix[i * cols + j];
        }
    }

    // 打印转置后的矩阵
    for (int i = 0; i < cols; i++) {
        for (int j = 0; j < rows; j++) {
            std::cout << transposedMatrix[i * rows + j] << " ";
        }
        std::cout << std::endl;
    }

    delete[] transposedMatrix;
}

int main() {
    int matrix[3][4] = {{1, 2, 3, 4},
                        {5, 6, 7, 8},
                        {9, 10, 11, 12}};

    int rows = 3;
    int cols = 4;

    transposeMatrix(&matrix[0][0], rows, cols);

    return 0;
}
