  Previous year placement questions:​

  
  1.void main()
  {
  int d=5;
  printf("%f",d);
  }
  Ans: Undefined
  2.
  void main()
  {
  int i;
  for(i=1;i<4,i++)
  switch(i)
  case 1: printf("%d",i);break;
  {
  case 2😛rintf("%d",i);break;
  case 3😛rintf("%d",i);break;
  }
  switch(i) case 4😛rintf("%d",i);
  }
  Ans: 1,2,3,4
  3.
  void main()
  {
  char *s="12345s ";
  printf("%d",sizeof(s));
  }
  Ans: 6
  4.
  void main()
  {
  unsigned i=1; /* unsigned char k= -1 => k=255; */
  signed j=-1; /* char k= -1 => k=65535 */
  /* unsigned or signed int k= -1 =>k=65535 */
  if(i printf("less");
  else
  if(i>j)
  printf("greater");
  else
  if(i==j)
  printf("equal");
  }
  Ans: less
  5.
  void main()
  {
  float j;
  j=1000*1000;
  printf("%f",j);
  }
  
  1. 1000000
  2. Overflow
  3. Error
  4. None
  Ans: 4
  6. How do you declare an array of N pointers to functions returning
  pointers to functions returning pointers to characters?
  
  Ans: The first part of this question can be answered in at least
  three ways:
  1. char *(*(*a[N])())();
  2. Build the declaration up incrementally, using typedefs:
  
  typedef char *pc; /* pointer to char */
  typedef pc fpc(); /* function returning pointer to char */
  typedef fpc *pfpc; /* pointer to above */
  typedef pfpc fpfpc(); /* function returning... */
  typedef fpfpc *pfpfpc; /* pointer to... */
  pfpfpc a[N]; /* array of... */
  3. Use the cdecl program, which turns English into C and vice
  versa:
  cdecl> declare a as array of pointer to function returning
  pointer to function returning pointer to char
  char *(*(*a[])())()
  cdecl can also explain complicated declarations, help with
  casts, and indicate which set of parentheses the arguments go in (for complicated function definitions, like the one above). Any good book on C should explain how to read these complicated C declarations "inside out" to understand them ("declaration mimics use"). The pointer-to-function declarations in the examples above have not included parameter type information. When the parameters have complicated types, declarations can *really* get messy. (Modern versions of cdecl can help here, too.)
  7. A structure pointer is defined of the type time . With 3 fields min,sec hours having pointers to intergers.
  Write the way to initialize the 2nd element to 10.
  
  8. In the above question an array of pointers is declared.
  Write the statement to initialize the 3rd element of the 2 element to 10;
  
  9.
  int f()
  void main()
  {
  f(1);
  f(1,2);
  f(1,2,3);
  }
  f(int i,int j,int k)
  {
  printf("%d %d %d",i,j,k);
  }
  
  What are the number of syntax errors in the above?
  
  Ans: None.
  10.
  void main()
  {
  int i=7;
  printf("%d",i++*i++);
  }
  
  Ans: 56
  
  11.
  #define one 0
  #ifdef one
  printf("one is defined ");
  #ifndef one
  printf("one is not defined ");
  
  Ans: "one is defined"
  
  
  12.
  void main()
  {
  int count=10,*temp,sum=0;
  temp=&count;
  *temp=20;
  temp=∑
  *temp=count;
  printf("%d %d %d ",count,*temp,sum);
  }
  
  Ans: 20 20 20
  
  
  13. There was question in c working only on unix machine with pattern matching.
  
  
  14. what is alloca()
  Ans : It allocates and frees memory after use/after getting out of scope
  
  15.
  main()
  {
  static i=3;
  printf("%d",i--);
  return i>0 ? main():0;
  }
  
  Ans: 321
  
  16.
  char *foo()
  {
  char result[100]);
  strcpy(result,"anything is good");
  return(result);
  }
  void main()
  {
  char *j;
  j=foo()
  printf("%s",j);
  }
  
  Ans: anything is good.
  
  17.
  void main()
  {
  char *s[]={ "dharma","hewlett-packard","siemens","ibm"};
  char **p;
  p=s;
  printf("%s",++*p);
  printf("%s",*p++);
  printf("%s",++*p);
  }
  Ans: "harma" (p->add(dharma) && (*p)->harma)
  "harma" (after printing, p->add(hewlett-packard) &&(*p)->harma)
  "ewlett-packard"

  Selection process:
  
  The process followed by HCL TECHNOLOGIES was:
  
  1) Written test
  2) Personal Interview
  
  
  Written test
  
  There were three sections in test
  
  1) VERBAL (25Questions- 25min) (Not that much tough)
  2) QUANT (25Questions - 35min)
  3) TECHNICAL (25 Questions- 35min) (C,C++ knowledge)
  4) APTITUDE (25 Questions -35min) (Number series, easy)
  
  Questions asked in interview:
  
  1)Difference b/w C & C++
  
  2) What are advantages of C++ over C?
  
  3) What is POLYMORPHYSM and how can we achieve it in our C++ programs?
  
  4) What will u do if u has a clash with your colleague?
  
  5) If u are given Extra work in the Office and Your girlfriend is waiting for you at the outside. Then what will u do?(Wondering at this question)
  😲
  6)Why did you choose this engineering trade?
