在实际的网络运行环境中，数据备份与恢复功能是非常重要的。一个实用的局域网应用系统设计中必须有网络数据备份，恢复手段和灾难恢复计划。请根据你对网络数据备份、恢复方面知识的了解，讨论以下几个问题：
1．如果需要你去完成一个网络备份系统的设计，你会考虑解决哪四个主要的问题？
2．备份网络文件就是将所需要的文件拷贝到光盘、磁带或磁盘符等存储介质上。对于重要的网络信息系统的软件与重要数据，有人提出需要有多个副本，并且其中一个副本需要异地存放，你觉得必要吗？为什么？
3．如果要你去审查一个网络备份系统的实际效果，你会重点考察的两个主要问题是什么？

软件维护是软件生命周期的重要组成，而影响维护的因素较多，除了人员因素、技术因素和管理因素外，还有程序自身的因素，具体影响因素可归纳为：
1)软件系统的规模：
2)软件系统的年龄：
3)软件系统的结构。
试回答以下问题：
1．给出上述三项因素的解释，阐述“规模”、“年龄”和“结构”的具体含义。
2．扼要分析影响维护工作量的因素，即分析可能增加维护工作量的因素和可能减少维护工作量的因素。
3．简单叙述软件可维护性度量的含义。

行政权力与行政责任之间的关系主要表现在哪几个方面？

已知数据文件IN44.DAT中存有300个4位数，并已调用读函数readDat()把这些数存入数组a中，请编制一函数isValue()，其功能是：求出千位数上的数减百位数上数减十位数上的数减个位数上的数大于零的数的个数cnt，再把所有满足此条件的4位数依次存入数组b中，然后对数组b的4位数按从小到大的顺序进行排序，最后调用写函数writeDat()把数组b中的数输出到OUT44.DAT文件中。
例如：9123，9-1-2-3＞0，则该数满足条件，存入数组b中，且个数cnt=cnt+1。
9812，9-8-1-2＜0，则该数不满足条件，忽略。
注意：部分源程序已给出。
程序中已定义数组：a[300]，b[300]，己定义变量：cnt。
请勿改动主函数main()、读函数readDat()和写函数writeDat()的内容。
试题程序：
include＜stdio.h＞
int a[300],b[300],cnt=0;
jsValue()
{
}
main ()
{
iht i;
readDat();
jsValue();
writeDat();
for(i=0;i＜cnt;i++)
printf("b[%d]=%d\n",i,b[i]);
}
readDat()
{
FILE fp;
int i;
fp=fopen("IN44.DAT","r");
printf ("cnt=%d\n", cnt);
for (i=0;i＜300; i++)
fscanf (fp, "%d, ", &a [i] );
fclose (fp);
}
writeDat ()
{
FILE fp;
int i;
fp=fopen ("OUT44. DAT" , "w" );
fprintf (fp, "%al\n", cnt);
for (i=0; i＜cnt;i++)
fprintf(fp, "%d\n",b[i]);
fclose (fp);
}
