The day of terror at the Virginia Polytechnic and State University in Blacksburg began at about 7:15 a. m. , with the shooting of a woman and a male resident adviser on the fourth floor of a dorm building on campus, Kristen Bensley, a freshman who lived below the floor where the shooting occurred, told TIME, "There were minors going on about the assailant was fighting with his girlfriend or something of that nature." Bensley notes that only residents can get into the building, using a specific "passport", that is, a card that one has to swipe in order to open doors before 10 a.m. If he was an outsider, someone would have had to let him in. Or more likely, he was a resident of the dorm himself. If so, how did be keep so much ammunition unnoticed

Unlike high schools, most universities can’t beef up security with a metal detector or two. So what can be done to protect students Other questions remain unanswered. Why was there a two-hour gap between the incident at the dorm and a far more fatal one across campus At one point, that led to theorizing that more than one gunman was involved. The gunman who killed at least 30 people at Norris Hall shortly after 9 a.m. was described by some sources as an Asian man.

It has been a surreal time for the students. Brandon Stiltner, a senior aerospace engineering student, and Jonathan Hess, a senior mechanical engineer, were watching TV all day but by noon they’d had enough. "We decided we needed to do something," Stiltner said. "We were worthless sitting around." So they took their six-foot Virginia Tech sign off the wall and logged into Facebook. Within the next few hours 100 people replied to their e-mail request for a vigil.

By 8 p.m. hundreds bf students began filing down the steps of the War Memorial Chapel toward the drill field. Clusters of two and three students stood together in silence. Slowly they began to line up to sign the board. "I’m still really in disbelief," says Stiltner. The shock of the day’s shootings sank in, Hess said, as he carried the sign across campus for the vigil. "It hit me," Hess said, "to know that it was in these buildings." The media crews that swarmed campus were also surreal to Hess and Stiltner. "We could look out our window and see exactly what’s on TV," Stiltner says. He watched his sign crowded with initials and prayers, awaiting the names of the victims, He shuddered. "I hope I don’t have any nasty surprises.

下列程序的功能是:选出100~1000间的所有个位数字与十位数字之和被10除所得余数恰是百位数字的素数(如293)。计算并输出上述这些素数的个数cnt,以及这些素数值的和sum。请编写函数countValue()实现程序要求,最后调用函数writeDAT()把结果cnt和sum输出到文件OUT17.DAT中。
注意:部分源程序已给出。
请勿改动主函数main()和写函数writeDAT()的内容。
试题程序:
#include <stdio.h>
int cnt, sum;
void countValue()


main()

cnt=sum=0;
countValue();
print f ("素数的个数=%d\n", cnt);
printf("满足条件素数值的和=%d", sum);
writeDAT();

writeDAT()

FILE *fp;
fp=fopen("OUT17.DAT", "w");
fprintf(fp, "%d\n%d\n", cnt, sum);
fclose(fp);
