A Test for The C Programming Language
  I. History
1. C was originally designed for and implemented on the (what) operating system on the DEC PDP-11, by (who) .
2. The most recently approved ANSI/ISO C standard was issued in (when), and single line comments notation “//” is or isn’t a feature of C89.
  II. Syntax and Semantics 1.In a runtime C program, auto variables are stored in , staticvariables are stored in , and function parameters are stored in .
  a. stack b. heap c. neither stack nor heap
2. The statement “extern int x;” is a , and the keyword extern is used during .
  a. variable declaration b. variable definition c. compilation time d. runtime
3. There is a complicated declaration: void ( * signal (int, void(*)(int)) ) (int);If a statement “typedef void (*p) (int);” is given,please rewrite this complicated declaration.
4. The following code is a segment of C program.
  ..........
  void func(int *p)
  {...........}
  ..........
  main()
  {
  int num=0;
  .........
  func(&nu(文章转载自[个人简历网] http://www.gerenjianli.com 请保留此标记)m);
  ........
  }
  ..........
Here, the function argument “&num” is passed .
 a. by value b. by reference
  III. Practice
  Create a tree, which has h (h>0) layers, and its each node has w(w>0) sub-nodes.Please complete the following incomplete solution.
  #include <stdlib.h>
  #include <string.h>
  struct tree{
  char info;
  p_sub; //link to sub-nodes};
  // allocate memory and initiate
  void dnode ( struct tree* tmp )
  {
  = malloc( sizeof (struct tree) );
  = 0x41;
  = NULL;
  }
  struct tree *dtree (struct tree* subtree, int height, int width)
  {
  int i;
  if ( !subtree ) //if necessary, allocte memory for subtree
  denode(subtree);
  if ( height == 1 )
  return subtree;
  else if ( height == 2 ) {
  struct tree *leaf = NULL;
  for ( i=0; i<width; i++ ) {
  denode ( );
  ;
  leaf = NULL;}
  return subtree;}
  else {
  for ( i=0; i<width; i++ ) {
  }
  return subtree;
  }
  }
  main()
  {
  .........
  struct tree *root = NULL;
