在△ABC中，a、b、c分别为内角A、B、C的对边，且2asinA=（2b+c）sinB+（2c+b）sinC．若sinB+sinC=1，求△ABC的各角的大小．

有以下程序：
#include ＜string.h＞
void f(char p[][10],int n)/* 字符串从小到大排序 */
char t[10]; int i,j;
for(i=0;i＜n-1;i++)
for(j=i+1;j＜n;j++)
if(strcmp(p[i],p[j])＞0)

strcpy(t,p[i]);
strcpy(p[i],p[j]);
strcpy(p[j],t);


main()
char p[5][10]="abc","aabdog","abbd","dcdbe","cd";
f(p,5);
printf("%d\n",strlen(p[0]));

程序运行后的输出结果是( )。

What makes Reader’s Digest the most successful magazine in publishing history Beneath the fun and excitement that fill our pages, we are, above all else, a serious magazine. Our readers are serious people. The Digest never loses sight of the fact that each day all of us confront a tough, challenging world. To millions who know our record of viewing this world, we are not a luxury; we are a necessity.

Basic to our magazine is a steady focus on the power of the individual. We show that man’s greatest ideas and accomplishment, his often stunning (极好的) faith and courage and hope, can be seen in the conduct of ordinary men and women. We reflect the universal skepticism that government can solve our problems; we herald the unending promise of self-determination and individual enterprise. Readers depend upon us for truth and accuracy, logic and common sense.

Our stories come from the grit of human experience-the tough, the tender, the funny. These stories—always told in a powerful narrative style—spring from love and caring, from a sense of right and wrong, from a dedication to the vitality (活力，生命力) of the human spirit. We are at the forefront of major issues of medicine, health, environment, human rights. We take readers behind the headlines to the cause and meaning of world events. We celebrate courage, champion adventure and always seek to expand the mind, and to enrich the spirit and the body. It is this clear voice—never preaching (说谎), always showing-that has made readers set us apart from all other magazines.

Deep within our widely varied package of humor, drama, and helpful information, there hums (哼唱) a subtle power that guides people in every aspect of their lives. They listen because what we put forth rings true. They are comfortable with our clear, concise words that inform them, entertain them, and remind them of those eternal values that fortify all decent people as they seek clarity and coherence in a confusing world. Our readers recognize that our compass is good for the long haul-that our principles are good for all seasons, good for all ages, good for all those who wish to play a role in making their world a better place. So long as we never lose sight of these powerful principles that are at the soul of our magazine-and so long as we remain at the cutting edge of life in our world—then we are prepared to lay claim to a future as brilliant and as exciting as our past.

According to the passage, the Digest will have a bright future as long as （）。

C. it keeps its language clear, concise and easy to understand
