矩阵的乘法运算

有两个矩阵A1,A2,编写一个程序，实现这两个矩阵的乘积。

#include <stdio.h>

int main(int argc, char *argv[])
{
  int A[2][3] = {{1,2,3},{4,5,6}};
  int B[3][4] = {{1,0,2,3},{4,1,5,6},{6,8,9,0}};
  int C[2][4] = {{0,0,0,0},{0,0,0,0}};

  int i,j,k;
  for(i = 0; i < 2; i++)
    for(j = 0; j < 4; j++)
      for(k = 0; k < 3; k++)
    C[i][j] += A[i][k] * B[k][j];

  printf("the result is\n");
  for(i = 0; i < 2; i++)
  {
    for(j = 0; j < 4; j++)
    {
      printf("%d ",C[i][j]);
    }
    printf("\n");
  }

  return 0;
}
