{
      Integer c , d = 2 
      c= a * d + b 
      return c 
}

Function calculate ()

 }
A . 80

B . 40

C . 32

D . 72

Answer : B . 40

Explanation :

    • c = ?
    • d = 2
    • c = a * d + b
    • c = a * 2 + b then a = 5 b = 20
    • c = ?
    • c = c + d
    • c = a * 2 + b + d
    c = 5 * 2 + 20 + 10 = 40

Ravi and Rupali are asked to write a program to sum the rows of 2X2 matrices stored in the array A.
Ravi writes the following code (Code A):

 for n = 0 to 1 
 sumRow1[n] = A[n][1] + A[n][2]
 end

Rupali writes the following code (Code B):

sumRow1[0] = A[0][1] + A[0][2] 
sumRow1[1] = A[1][1] + A[1][2]

Comment upon these codes (Assume no loop unrolling done by compiler) ?

A. Code a will execute faster than b.

B. Code b will execute faster than a.

C. Code a is logically incorrect.

D. Code b is logically incorrect

Answer : B. Code b will execute faster than a

Explanation:

  • Both codes are taking two steps of operation, so same complexity.
  • But if we consider the overhead of looping (as it takes time to increment counter) then code b will be faster.

The construct “if (condition) then A else B” is used for which of the following purposes ?

A. Decision making

B. Iteration

C. Recursion

D. Object oriented programming

Answer : A. Decision making

Explanation:

If-Else for Decision Making:

  • The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won’t. But what if we want to do something else if the condition is false. Here comes the else statement. We can use the else statement with if statement to execute a block of code when the condition is false.

Ashima wants to print a pattern which includes checking and changing a variables value iteratively She decides to use a loop/condition Which of the following options should she use such that the body of the loop/condition is executed at least once whether the variable satisfies the entering condition or not ?

A. For loop

B. While loop

C. Do-while loop

D. Switch case

E. None of these

Answer : C. Do-while loop

Explanation:

Do While Loop :

  • Unlike for and while loops, which test the loop condition at the top of the loop, the do…while loop in C programming checks its condition at the bottom of the loop.
  • A do…while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time.

Syntax for Do While Loop :

do {
     statement(s);
}    while( condition );

      What is space complexity of the program ?

      A. Amount of hard disk space required to store the program

      B. Amount of hard disk space required to compile the program

      C. Amount of memory required by the program to run

      D. Amount of memory required by the program to compile

      Answer : C. Amount of memory required by the program to run

      Explanation :

      • Space complexity is a measure of how efficient your code is in terms of memory used.

      A. Omega(n)

      B. Omega(n2)

      C. Theta (n)

      D. Theta (n2)

      Answer : D. Theta(n2)

      Explanation:

      • The multiplication involved will use two for loops and hence the complexity will be Theta(n2)

      A. O(N)

      B. O(N2)

      C. O(N3)

      D. None of these

      Answer : B. O(N2)

      Explanation :

      • Time complexity will be O(n2), because if we add all the elements one by one to other matrics we have to traverse the whole matrix at least 1 time and traversion takes O(n2) times.
      • With this traversion we add 3 elements of location [ i, j ] and storing the result on other matrix at [ i, j ] location.
