What is it that makes a house a home ? A home is a place of companionship with people in it who love each other , who are harmonious and closer inside with one another than they are outside with those in the workplace or with classmates at school . A home is a place of companionship that it’s difficult to leave. In a home there is love , sharing and appreciation , and the members help each other .

I have seen families on the street. But if they live , sleep , talk , and eat together , they are a family, even if they are poorly off. You don’t need a roof to make a home. The truly homeless are some of the rich people who build multi-million-dollar houses and are too busy to live in them . The truly homeless are those who have turned their home into a hotel lobby . The parents work. The children do wrong . They don’t talk and eat together every day . They rarely see each other . The truly homeless people are those with babysitters , caretakers , gardeners and maids. Parents are unaware , too busy making money outside the home that they don’t live in . This is another way of looking at the rich and the homeless . Who is to be pitied ?

Control of the computer and the Internet is also important to make a house into a home. If the computer is on all the time , the house turns into an office, even if everyone is at home . Many homes these days are just offices. Human communication has stopped . The computer eats up the time that one should be giving to others within the home . Using the computer moderately gives us time for gentleness , play and communication , not with a screen , but with a human being.

已知在文件IN61.DAT中存有100个产品销售记录，每个产品销售记录由产品代码dm(字符型4位)、产品名称mc(字符型10位)、单价dj (整型)、数量s1(整型)、金额je(长整型)几部分组成。其中，金额二单价X数量可计算得出。函数ReadDat()的功能是读取这100个销售记录并存入数组sell中。请编制函数 SortDat()，其功能要求：按金额从小到大进行排列，若金额相同，则按产品代码从大到小进行排列，最、终排列结果仍存入结构数组sell中，最后调用函数WriteDat()把结果输出到文件OUT61.DAT中。
注意：部分源程序己给出。
请勿改动主函数main()、读函数ReadDat()和写函数WriteDat()的内容。
