  for you they seems to be easy but for me like Schrödinger equation

  if you know Structure you also know Union
  
  they are collection of various data types but have a difference
  
  The memory of Structure is equal to the sum of the memory of all the data types
  
  But Union takes only the largest value only
  
  Say we have a char, int then memory for structure will be 3 while Union it will be 2

  Syntax error is the error in the syntax that is use forget to follow the rules of writing code in C
  
  it means you forget a ';' or make a spelling mistake of 'printf to be pintf'
  
  Semantics are the logical errors they are generally not recognised by the compiler with exceptions of divide by zero
  
  Semantics means you have done a+b when you had to do a+c

  Can you give justification for your answer?

  Q1. Distinguish between (*m)[5] and *m[5]?

  (*m)[5] means "pointer to an array of 5 integers"
  *m[5] means "array of integer pointers"
  
  As for the Input/Output stream question, I'm not sure, but I think that they are interfaces provided to the programmer to ensure that he does not have to worry about the actual implementation of input/output (i.e. writing individual bytes to printer or monitor etc.).

  Thanks Gaurav
  
  And as far as input/output stream are concerned
  
  Stream is an array of bytes
  
  all the input output of the values is considered as a stream of bytes by the compiler
  
  an int variable has 2 bytes , a char has 1 byte
  
  When the input and output is performed it is considered as bytes

  main()
  {

  int a=10, b=20, c=30, d;
  d = a > b ? (a > c ? a : c) : b > c ? b : c;
  printf ("%d",d);
  ​

  }
  first of all it will check whether a>b ie not true so it check b>c which is again false
  so it will give value 30
  I hope my answer is not wrong

  You are absolutely correct. Good Job!

  I don't know about Input/Output stream.
  
  Sarveshgupta may be correct.

  main()
  {
  printf("%%%%%",7);
  }
  what is the output:
  1:7
  2:error
  3:%%%
  4:%%%%%

  It gives syntax error 😀
  
  The bracket mustbe } not {
  
  PS.Start new thread for questions 😀

  sarveshgupta

  I think he has placed that bracket by mistake
  
  and printf has everything inside double quotes except the variables whose values are to be substituted with their type specifiers
  Hope i am correct
