write a C program to calculate the multiplication of two matrices using two_dimensional array. Requirement Getting input from users

下面是一个使用二维数组计算两个矩阵乘积的C语言程序，可以从用户获取输入：

#include <stdio.h>

int main() {
   int m, n, p, q, c, d, k, sum = 0;
   int first[10][10], second[10][10], multiply[10][10];

   printf("Enter the number of rows and columns of first matrix: ");
   scanf("%d%d", &m, &n);

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

   for (c = 0; c < m; c++)
      for (d = 0; d < n; d++)
         scanf("%d", &first[c][d]);
      
   printf("Enter the number of rows and columns of second matrix: ");
   scanf("%d%d", &p, &q);

   if (n != p)
      printf("The matrices cannot be multiplied with each other.\n");
   else {
      printf("Enter the elements of second matrix:\n");

      for (c = 0; c < p; c++)
         for (d = 0; d < q; d++)
            scanf("%d", &second[c][d]);

      for (c = 0; c < m; c++) {
         for (d = 0; d < q; d++) {
            for (k = 0; k < p; k++) {
               sum = sum + first[c][k]*second[k][d];
            }

            multiply[c][d] = sum;
            sum = 0;
         }
      }

      printf("Product of the matrices:\n");

      for (c = 0; c < m; c++) {
         for (d = 0; d < q; d++)
            printf("%d\t", multiply[c][d]);

         printf("\n");
      }
   }

   return 0;
}

该程序通过提示用户输入每个矩阵的行和列数，并分别提示输入每个矩阵的元素。然后它检查两个矩阵是否可以相乘，如果可以，则计算两个矩阵的乘积并将其存储在一个名为multiply的二维数组中，最后打印输出结果。
