Fifty years ago, on May 25, 1961, US President John F. Kennedy (31) a grand challenge that changed the world (32) humankind knew it— (33) a man to the Moon and bring him home again, and to do it by the end of the decade. It is one of the most (34) images of all time an Earthling (35) foot upon the Moon for the first time. The moment was immortalized by astronaut Neil Armstrong. "One small step for a man, one giant (36) for mankind," said Armstrong. The challenge to put a man on the Moon had been issued on May 25, 1961, by newly elected President John F. Kennedy in a bold speech before Congress. "First, I believe that this nation (37) commit itself to (38) the goal, before this decade is out, (39) landing a man on the Moon and returning him safely to the earth. No (40) space project in this period will be more (41) to mankind, or more important in the long-range exploration of space; and none will be so difficult or expensive to accomplish..." said President Kennedy. To set the stage for this speech, here is a bit of history: In 1957, the Soviet Union (42) Sputnik—the first (43) object (44) placed into orbit around Earth. And only one month before Kennedy’s speech, the Soviets sent the first man into space, Yuri Gagarin. Three weeks later an American (45) suit—Alan Shepard, who admired the view from his Freedom Seven Mercury space capsule. "On the periscope—what a beautiful view," said Shepard. "Cloud cover over Florida." The Space Race was well (46) . The Apollo Eleven (47) was the first manned mission to land on the Moon. It was the fifth human spaceflight of Project Apollo and the third human (48) to the Moon. It was also the second all-veteran crew in manned spaceflight history. Launched on July 16, 1969, it carried Mission Commander Neil Alden Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin Eugene "Buzz" Aldrin, Jr. On July 20, Armstrong and Aldrin became the first (49) to land on the Moon, while Collins orbited above. The mission fulfilled President John F. Kennedy’s goal of reaching the moon (50) the end of the 1960s.
已知在文件IN54.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je(长整型)几部分组成。其中，金额=单价×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：按金额从大到小进行排列，若金额相同，则按产品名称从小到大进行排列，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 OUT54.DAT中。 注意：部分源程序已给出。 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＞ #include＜mem.h＞ #include＜string.h＞ #include＜conio.h＞ #include＜stdlib.h＞ #define MAX 100 typedef struct char dm[5]; char mc[11]; int dj; int sl; long je; PRO; PRO 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[11]; int i; fP=fopen("IN54.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; fclose(fp); void WriteDat() FILE *fp; int i; fP=fopen("OUT54.DAT","W,); for(i=0;i＜100;i++) fprintf(fp,"%s %s %4d %5d %101d\n",sell[i].dm, sell[i].mc, sell[i].dj,sell[i].sl, sell[i].je); fclose(fp);
