  hi SarveshGupta,
  Your answer is right, but i am confused with the answer. Can you explain me the process ?

  i++ means using post increment that is when we use it in any expression it uses the current value of that variable that is being carried forward from previous statement and then increment after compiler reads it so that any next time compiler reads the variable again it will read the incremented value
  
  now we are doing i++ * i++ this implies
  
  first time the value read is 7 which was the initial value of i and it gets incremented so for next operand i++ it takes the value 8 and after using 8 it increments it to 9
  
  since we are using them only till here we get the value as 7*8 =56
  if we try to print the value of i at the end of the program it will be 9
  
  

  void main()
  {
  int i=7;
  printf("%d \n",i++*i++);
  printf("%d",i);
  }

  will give the output as:
  
  

  56
  9

  Dear sarveshgupta,
  Your answer is right, but you stated as 7*8 why i can be 8*7,
  bcoz, if execution is being handled from right to left.

  Good Point. In fact printf statement handles execution from right to left (in C).
  In this case it won't affect the answer in either case.

  Ya I am sorry for writing it that way but i actually meant 8 * 7 as I know printf reads from right to left
  
  I wrote it simply missing the order of writing
