使用C语言，数据结构编写m*n矩阵和q*k矩阵的乘法

#include <stdio.h>

#define MAX_SIZE 100

int main() {
    int m, n, q, k;
    int matrix1[MAX_SIZE][MAX_SIZE], matrix2[MAX_SIZE][MAX_SIZE], result[MAX_SIZE][MAX_SIZE];

    printf("Enter the size of the first matrix (m x n): ");
    scanf("%d %d", &m, &n);

    printf("Enter the size of the second matrix (q x k): ");
    scanf("%d %d", &q, &k);

    if (n != q) {
        printf("The matrices cannot be multiplied.\n");
        return 0;
    }

    printf("Enter the elements of the first matrix:\n");

    for (int i = 0; i < m; i++) {
        for (int j = 0; j < n; j++) {
            scanf("%d", &matrix1[i][j]);
        }
    }

    printf("Enter the elements of the second matrix:\n");

    for (int i = 0; i < q; i++) {
        for (int j = 0; j < k; j++) {
            scanf("%d", &matrix2[i][j]);
        }
    }

    // Multiply the matrices
    for (int i = 0; i < m; i++) {
        for (int j = 0; j < k; j++) {
            result[i][j] = 0;
            for (int l = 0; l < n; l++) {
                result[i][j] += matrix1[i][l] * matrix2[l][j];
            }
        }
    }

    // Print the result matrix
    printf("The product of the matrices is:\n");

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

    return 0;
}
