Yes, we can!

“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.”

        现在无论是学习外语还是普通的计算机应用,手边每时每刻都需要一个字典软件。从我开始使用电子辞典至今用过不下十几个版本的字典了,它们当中有几款很经典,因此在这篇文章中做一个汇总。

1. 灵格斯词霸(www.lingoes.cn)

        灵格斯词霸在普通用户群体中应该是和金山词霸有着同等地位的,但它的扩展性更好,几乎主流的字典都可以在它的官网上找到对应的灵格斯版本。以下是我认为比较好的几款字典:

牛津高阶英汉双解词典
朗文当代英语词典
麦克米兰英语词典 – American

其实这个程序很菜,用的方法也很笨拙,主要的目的只是为了让它从字面上能更好的被理解,大家见笑。

#include “stdio.h”

int main(void)
{
     int m,s,n; //matrix’s columns and rows
     float a[50][50],b[50][50],c[50][50]; //arrays to store your matrixes.
    
     int i,j,k; //loop control.

         for (j=0;j<50;j++)
            a[i][j]=b[i][j]=c[i][j]=0.0; //initialize
