已知在文件IN1.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)五部分组成。其中：金额＝单价×数量。函数ReadDat()的功能是读取这100个销售记录并存入结构数组.sell中。请编制函数SortDat()，其功能要求：按产品名称从小到大进行排列，若产品名称相同，则按金额从小到大进行排列，最终排列结果仍存入结构数组sell中，最后调用函数WriteDat()把结果输出到文件OUT1.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]includeincludeincludeincludeincludedefine MAX 100typedef struct{ char dm[5]; /*产品代码* /char mc[11]; /*产品名称*/int dj; /*单价* /int si; /*数量*/long je; /*金额*/}PRO;PRO sell[-MAX];void ReadDat() ;void WriteDat() ;void SortDat(){}main(){memset(sell,0,sizeof(sell));ReadDat();SortDat();WriteDat();}void ReadDat(){FILE *fp;char str[80],ch[11];int i;fp=fopen("IN1.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].s1=atoi(ch);sell[i].je=(long)sell[i].dj * sell[i].s1;}fclose(fp);}void WriteDat(){FILE * fp;int i;fp=fopen("OUT1.DAT","w");for(i=0;i100;i++)fprintf(fp,"%s%s%4d%5d%101d\n",sell[i].dm,sell[i].mc,sell[i].dj,sell[i].s1,sell[i].je)fclose(fp);}
