已知在文件IN. 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code(字符型4位)、产品名称name(字符型10位)、单价uprice(整型)、数量amount(整型)、金额sum(长整型)5部分组成。其中：金额=单价×数量。函数Rdata()是读取这100个销售记录并存入结构数组sell中。请编写函数SortDat()，其功能要求：按金额从小到大进行排列，若金额相等，则按产品代码从小到大进行排列，最终排列结果仍存入结构数组sell中。最后调用函数Wdata()，把结果输出到OUT. dat文件中。注意：部分源程序已经给出。请勿改动主函数main()、读数据函数Rdata()和输出数据函数Wdata()的内容。include ＜stdio. h＞include ＜string. h＞include ＜conio. h＞include ＜stdlib. h＞define MAX 100typedef struct{ char code[5]; /* 产品代码 */char name[11]; /* 产品名称 */int uprice; /* 单价 */int amount; /* 数量 */long sum; /* 金额 */} PRO;PRO sell [MAX];void Rdata();void Wdata();void SortDat(){}void main (){ memset(sell, 0, sizeof(sell)Rdata();SortDat();Wdata();}void Rdata(){ FILE *fp;char str[80], ch[11];int i;fp = fopen("IN. dat", "r");for (i=0; i＜100; i++){ fgets(str, 80, fp);memcpy(sell[i].code, str, 4);memcpy(sell[i].name, str+4, 10);memcpy(ch, str+14, 4);ch[4] = 0;sell[i].uprice = atoi(ch);memcpy(ch, str+18, 5);ch[5] = 0;sell[i]. amount = atoi(ch);sell[i].sum = (long)sell[i]. uprice * sell[i]. amount;}fclose(fp);}void Wdata(){ FILE *fp;int i;fp = fopen("OUT. dat", "w");for (i=0; i＜100; i++){ printf("%s %s %4d %5d %5d\n", sell[i]. code, sell[i].name,sell[i].uprice, sell[i]. amount, sell[i]. sum);fprintf(fp, "%s %s %4d %5d %5d\n", sell[i]. code,sell[i]. name, sell[i]. uprice, sell[i]. amount, sell[i]. sum);}fclose(fp);}

问答题There is one passage in this section with 5 statements. Go over the passage quickly and answer the questions on the Answer Sheet. For questions 1-5, mark Y (for YES) if the statement agrees with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is becoming less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, even in remote jungles on the far side of the globe, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply over-sensitive to changes in the ecosystem? Could their rapid decline in numbers be signalling some coming environmental disaster for us all? This frightening scenario is in part the consequence of a dramatic increase over the last quarter of a century in the development of once natural areas of wet marshland: home not only to frogs but to all manner of wildlife. Yet, there are no obvious reasons why certain frog species are disappearing from rainforests in the Southern Hemisphere which are barely touched by human hands. The mystery is unsettling to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe. An example of a bizarre occurrence regarding a species of frog dates from the summer of 1995, when “an explosion” of multi-coloured frogs of the species Rana klepton esculenta occurred in the Netherlands. Normally these frogs are brown and greenish-brown, but some unknown contributory factor is turning these frogs yellow and / or orange. Nonetheless, so far, the unusual bi- and even tri-coloured frogs are functioning similarly to their normal-skinned contemporaries. It is thought that frogs with lighter coloured skins might be more likely to survive in an increasingly warm climate due to global warming. One theory put forward to explain extinct amphibian species that seems to fit the facts concerns the depletion of the ozone layer, a well-documented phenomenon which has led to a sharp increase in ultraviolet radiation levels. The ozone layer is meant to shield the Earth from UV rays, but increased radiation may be having a greater effect upon frog populations than previously believed. Another theory is that worldwide temperature increases are upsetting the breeding cycles of frogs. Statements: 1．Biologists are unable to explain why frogs are dying out. 2．Attempts are being made to halt the development of wet marshland. 3．Frogs are important in the ecosystem because they control pests. 4．It is not known why Dutch frogs are changing colour. 5．It is a fact that frogs’ breeding cycle has been upset by worldwide increases in temperature.
