  26 完成程序,实现对数组的降序排序

  #include

  void sort( );

  int main()

  {

  int array[]={45,56,76,234,1,34,23,2,3}; //数字任//意给出

  sort( );

  return 0;

  }

  27 费波那其数列,1,1,2,3,5……编写程序求第十项。可以用递归,也可以用其他方

  法,但要说明你选择的理由。

  #include

  int Pheponatch(int);

  int main()

  {

  printf("The 10th is %d",Pheponatch(10));

  return 0;

  }

  int Pheponatch(int N)

  {

  28 下列程序运行时会崩溃,请找出错误并改正,并且说明原因。

  #include

  #include

  typedef struct{

  TNode left;

  TNode right;

  int value;

  } TNode;

  TNode root=NULL;

  void append(int N);

  int main()

  {

  append(63);

  append(45);

  append(32);

  append(77);

  append(96);

  append(21);

  append(17); // Again, 数字任意给出

  }

  void append(int N)

  {

  TNode NewNode=(TNode )malloc(sizeof(TNode));

  NewNode->value=N;

  if(root==NULL)

  {

  root=NewNode;

  return;

  }

  else

  {

  TNode temp;

  temp=root;

  while((N>=temp.value && temp.left!=NULL) || (N

  NULL

  ))

  {

  while(N>=temp.value && temp.left!=NULL)

  temp=temp.left;

  while(N

  temp=temp.right;

  }

  if(N>=temp.value)

  temp.left=NewNode;

  else

  temp.right=NewNode;

  return;

  }

  }

  c. no difference

  31. For a class what would happen if we call a class’s constructor from with

  the same class’s constructor .

  a. compilation error b. linking error

  c. stack overflow d. none of the above

  32. “new” in c++ is a: .

  a. library function like malloc in c

  b. key word c. operator

  d. none of the above

  33. Which of the following information is not contained in an inode .

  a. file owner b. file size

  c. file name d. disk address

  34. What’s the number of comparisons in the worst case to merge two sorted li

  sts containing n elements each .

  a. 2n b.2n-1 c.2n+1 d.2n-2

  35. Time complexity of n algorithm T(n), where n is the input size ,is T(n)=T(

  n-1)+1/n if n>1 otherwise 1 the order of this algorithm is .

  a. log (n) b. n c. n^2 d. n^n

  36. The number of 1’s in the binary rePsentation of 34096+ 15256+516+3 a

  re .

  a. 8 b. 9 c. 10 d. 12

  37.设计函数 int atoi(char s)。

  38.int i=(j=4,k=8,l=16,m=32); printf(“%d”, i); 输出是多少?

  39.解释局部变量、全局变量和静态变量的含义。

  40.解释堆和栈的区别。

  41.论述含参数的宏与函数的优缺点。

  42. 以下三条输出语句分别输出什么?[C易]

  char str1[] = "abc";

  char str2[] = "abc";

  const char str3[] = "abc";

  const char str4[] = "abc";

  const char str5 = "abc";

  const char str6 = "abc";

  cout << boolalpha << ( str1==str2 ) << endl; // 输出什么?

  cout << boolalpha << ( str3==str4 ) << endl; // 输出什么?

  cout << boolalpha << ( str5==str6 ) << endl; // 输出什么?

  答:分别输出false,false,true。str1和str2都是字符数组,每个都有其自己的存储区,它们的值则是各存储区首地址,不等;str3和str4同上,只是按const语义,它们所指向的数据区不能修改。str5和str6并非数组而是字符指针,并不分配存储区,其后的“abc”以常量形式存于静态数据区,而它们自己仅是指向该区首地址的指针,相等。
