已知在文件IN9.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sl(整型)、金额je(长整型)五部分组成。其中，金额=单价X数量。函数ReadDat()的功能是读取这100个销售汜录并存入数组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，则按产品代码从小到大进行排列，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OUT9.DAT中。注意：部分源程序已给出。请勿改动主函数main()、读数据函数ReadDat()和输出数据函数WriteDat()的内容。[试题程序]include＜stdio.h＞include＜memory.h＞include＜string.h＞include＜conio.h＞include＜stdlib.h＞define MAX 100typedef struct{char dm[5] /*产品代码*/char mc[11]； /*产品名称*/int dj； /*单价*/int sl； /*数量*/long je； /*金额*/}PRO；PR()sell[MAX];void ReadDat()；void WriteDat()；void SortDat(){}void main(){memset(sell,0,sizeof(sell))；ReadDat()；SortDat()；WriteDat()；}void ReadDat(){FILE*fp；char str[80],ch[ll]；int i；fp=fopen("IN9.DAT","r")；for(i=0；i＜100；i++){fgets(str,80,fp)；memcpy(sell[i].dm,str,4)；memcpy(sell[i].mc,str+4,10)；memcpy(ch.str+14,4)；ch[4]=0；sell[i].dj=atoi(ch)；memcpy(ch,str+18,5)；ch[5]=0；sell[i].sl=atoi(ch)；sell[i].je=(long)sell[i].dj*sell[i].sl；}fclosc(fp)；}void WriteDat(){FILE *fP；Int i；fp=fopen("OUT9.DAT","w")；for(i=0；i＜100；i++)fprintf(fp,"%s %s %4d %5d %101d＼n",sell[i].dm,sell[i].mc,sell[i].sl,sell[i].sl,sell[i].je)；fclose(fp)；}
