//变长数组 相乘取结果
#include <stdio.h>

int main(void){

	//
	int array_01[3][4] = {1,2,3,4,5,6,7,8,9,10,11,12};
	int array_02[4][3] = {12,11,10,9,8,7,6,5,4,3,2,1};

	int result[3][3] = {0};

	int i, j, k;

	for (i = 0; i < 3; i ++){					//遍历array_01数组元素
		for (j = 0;j < 3; j ++){				//	遍历array_02数组元素
			for (k = 0; k < 4; k++ ){			//赋给第三个数组
				c[i][j] += a[i][k] * b[k][j];	//返回结果
			}
		}

	}


	//打印输出
	for (i = 0; i < 3; i ++){
		for (j = 0; j < 3; j ++){
			printf("%4d",c[i][j]);			
		}
		printf("\n");
	}

	return 0;
