Siri. The intelligent assistant that helps you get things done. All you have to do is ask.

Now you can use your voice to use your iPhone 4S. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.

Dual-core A5 chip: the most powerful iPhone ever.

And no matter what you’re doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life.

FaceTime. It’s even better face-to-face.

FaceTime of iPhone 4S lets you hear a voice and see the face that goes with it—iPhone to iPhone, iPad 2, iPod touch, or Mac over Wi-Fi. So no matter where they are, no matter where you are, you’ll always be there. Making a FaceTime call is just as easy as making a phone call. And it’s even easier with Siri.

请编一个函数void fun( int tt[M][N]， int pp[N]， tt指向一个M行N列的二维数组，求出二维数组每列中最大元素，并依次放入pp所指的一维数组中。二维数组中的数已在主函数中给出。 注意：部分源程序给出如下。 请勿改动主函数main和其他函数中的任何内容，仅在函数fun的花括号中填入所编写的若干语句。 试题程序： #include ＜conio.h＞ #include ＜stdio.h＞ #define M 3 #define N 4 void fun(int tt[M][N]，int pp[N]) { } main() { int t[M] [N]={{68，32，54，12}，{14，24，88， 58}，{42， 22， 44， 56}}； int p[N]，i，j，k； clrscr()； printf("The riginal data is：\n")； for(i=0；i＜M；i++) { for(j=0；j＜N；j++)printf("%6d"，t[i][j])； printf("\n")； } fun(t，p)； printf("\nThe result is：\n")； for(k=0；k＜N；k++) printf("%4d"，p[k])； printf("\n")； }
