编程基本功——矩阵的乘法运算

一、分析

二、源码

#include "stdio.h"

int main()

{

 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;

}
