1st two k answers 100% pata hein.... baaqi ka ki samajh ni ayi

 1) Consider the following pseudo code                                                                                               

declare a stack of characters
        while ( there are more characters in the word to read )
        {
           read a character
           push the character on the stack
        }
        while ( the stack is not empty )
        {
           pop a character off the stack
           write the character to the screen
        } 

       What is written to the screen for the input "apples"?
       ► selpa

       ► selppa

       ► apples

      ►aaappppplleess

2)  Consider the following function:

void test_a(int n)

{

cout << n << " ";

if (n>0)

test_a(n-2);

}

What is printed by the call test_a(4)?

       ► 4 2

       ► 0 2 4

       ► 0 2

       ► 2 4

3)Suppose you implement a Min heap (with the smallest element on top) in an array. Consider the different arrays below; determine the one that cannot possibly be a heap:                

       ► 16, 18, 20, 22, 24, 28, 30  

       ► 16, 20, 18, 24, 22, 30, 28

       ► 16, 24, 18, 28, 30, 20, 22

       ► 16, 24, 20, 30, 28, 18, 22

4) Do you see any problem in the code of nextInOrder below:

TreeNode * nextInorder(TreeNode * p)

{

   if(p->RTH == thread)

     return( p->R );

   else {

     p = p->R;

   while(p->LTH == child)

  p = p->R;

   return p;

   }

}  ►The function has no problem and will fulfill the purpose successfully. 

       ►  The function cannot be compile as it has syntax error. 

       ►  The function has logical problem, therefore, it will not work properly. 

       ►  The function will be compiled but will throw runtime exception immediately after the control is transferred to this function.
