Question 192


Write in Short

Short Answer▾

What is the output of the following program?

  1. voidmain ()
  2. {
  3.     staticinti =i ++, j =j ++, k =k ++;
  4.     printf (i =%dj =%dk =%d, i, j, k);
  5. }


In the program

Table Shows the Program
static int i = i ++ , j = j ++ , k = k ++ ;Here given the static integer variable i, j and k.

Since static variables are initialized to zero by default.

Then the all variables post increment of i, j and k are 1

printf (i =% d j =% d k =% d, i, j, k) ;Printf prints the value of i = 1 , j = 1 and k = 1

Question 193



Memory allocation of variables declared in a program is


Choice (4)


allocated in RAM.


allocated in ROM.


assigned to registers.


allocated on stack.




Memory Allocation
  • Variables declared in a program are allocated on the stack.
  • In a stack data is added or removed in a last in first out manner.
  • If a region of memory lies on the thread՚s stack, that memory is said to have been allocated on the stack.
  • Stack-based memory allocation is very simple and typically faster than heap-based memory allocation.
  • Memory on heap is allocated dynamically by the program.
  • Stack based allocation is suitable for temporary data or data which is no longer required after the creating function exits.
