用c语言写一段求解两个3*3矩阵的乘积，并输出结果的代码

#include <stdio.h>

int main() {
    int matrix1[3][3] = {{1,2,3}, {4,5,6}, {7,8,9}};
    int matrix2[3][3] = {{9,8,7}, {6,5,4}, {3,2,1}};
    int result[3][3] = {0};

    // 计算乘积
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            for (int k = 0; k < 3; k++) {
                result[i][j] += matrix1[i][k] * matrix2[k][j];
            }
        }
    }

    // 输出结果
    printf("Matrix 1:\n");
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            printf("%d ", matrix1[i][j]);
        }
        printf("\n");
    }

    printf("Matrix 2:\n");
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            printf("%d ", matrix2[i][j]);
        }
        printf("\n");
    }

    printf("Result:\n");
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            printf("%d ", result[i][j]);
        }
        printf("\n");
    }

    return 0;
}
