  as the game everyone will answer it ..
  ok 1st my turn,,,

  #include
  
  int main()
  {
  
  printf("%d",printf("computer"));
  
  return (0);
  
  }

  Answer:computer8
  First it will print computer and printf() is a predefined function it will return how many characters printed In this case it is printing 8 characters it will return 8.

  answer is computer8 as printf will return the number charcters enclosed within it's function parentheses and one clue is the format specifier %d that is usually used with numbers.

  Note: Please wrap your code in

  tags so that it looks nice and properly formatted 😀
  
  Example:
  
  

  #include
  
  int main()
  {
  
  printf("%d",printf("computer"));
  
  return (0);
  
  }

  Well i' value will be printed 5 times.
  1010101010(as no space and newline demand in your program).

  check the output of this code :
  
  
  

  #include
  
  int main()
  {
    int i;
  
    for(i=0;i<5;i++);
      {
        int i = 10;
   
          printf("%d",i);
      }
    return (0);
  }

  I think this thread is to give output of tricky codes, whereas in other one we have to give solutions for problems.
  Here is another one:
  Give the output of the following program:
  

  #include
  int main() {
  int i=1;
  for(i=1,j=5;i<5;i++,j--)
  {
    printf("%c  %c\n",i,j);    
  }
  }

  @#-Link-Snipped-# I guess multiple declaration of i=1 won't be allowed.
  
  and %c (meant for characters) is not valid format specifier for printing integers.
  So I guess the above program will give a wierd o/p.

  Actually I used C++ compiler so that multiple declaration didn't gave error (but will give error in C compiler)😁. So it's edited 👍.

  And u have to guess that weird o/p 😀

  a number printed in %c format specifier would get converted to it's equivalent character in terms of ascii codes.So it might be a sort of symbols.
  
  Correct me if i'm wrong.

  Yes u are right. It will print different characters like smile face, diamonds, hearts etc.

  #include
  
  int main()
  {
  static   int i;
  
    for(i=0;i<5;i++);
      {
        static int i = 10;
  
          printf("%d",i);
      }
    return (0);

  #-Link-Snipped-# 

  I think that i'll give a compile time error because the variable j is not declared

  #include int main(){ int i=1; for(i=1,j=5;i<5;i++,j--) { printf("%c %c\n",i,j); } }
