Question 1

Pick the best statement for the below program:

  • Compile error because arr has been defined using struct type incorrectly. First struct type should be defined using tag and then arr should be defined using that tag.

  • Compile error because apart from definition of arr, another issue is in the initialization of array of struct i.e. arr[].

  • Compile error because of initialization of array of struct i.e. arr[].

  • No compile error and it’ll print 1 0 2 0

Question 2

Pick the best statement for the below program:
  • Compile error because struct type (containing two fields i.e. an array of int and an int) has been specified along with the definition of array arr[] of this struct type.
  • Compile error because of incorrect syntax for initialization of array arr[].
  • No compile error and two elements of arr[] would be defined and initialized. Output would be “1 0 1 and 2 0 2”.
  • No compile error and two elements of arr[] would be defined and initialized. Output would be “1 X 1 and 2 X 2” where X is some garbage random number.

Question 3

Pick the best statement for the below program: 

  • Compile error because struct type (containing two fields of dissimilar type i.e. an int and a char) has been mentioned along with definition of myVar of that struct type.

  • Compile error because of incorrect syntax of initialization of myVar. Basically, member of operator (i.e. dot .) has been used without myVar.

  • Compile error for not only B but for incorrect order of fields in myVar i.e. field c has been initialized first and then field i has been initialized.

  • No compile error and it’ll print 100 A.

Question 4

Pick the best statement for the below program: 

  • Compile error due to incorrect syntax of initialization.

  • No compile error and it’ll print “0 100”.

  • No compile error and it’ll print “100 100”.

  • Compilation error.

Question 5

Pick the best statement for the below program snippet: 

  • No compile error and it’ll create array arr of 2 elements. Each of the element of arr contain a struct field of int array of 2 elements. arr[0]. a[0] would be 1 and arr[1].a[0] would be 2.

  • No compile error and it’ll create array arr of 2 elements. Each of the element of arr contain a struct field of int array of 2 elements. arr[0]. a[0] would be 1 and arr[0].a[1] would be 2. The second element arr[1] would be ZERO i.e. arr[1].a[0] and arr[1].a[1] would be 0.

  • No compile error and it’ll create array arr of 1 element. Each of the element of arr contain a struct field of int array of 2 elements. arr[0]. a[0] would be 1 and arr[0].a[1] would be 2.

  • None of the above

Question 6

Consider the code fragment below : 

What does f(173) print?

  • 010110101

  • 010101101

  • 10110101

  • 10101101

Question 7

Consider the code fragment written in C below : 

Which of the following implementations will produce the same output for f(173) as the above code? P1 

P2 

  • Both P1 and P2

  • P2 only

  • P1 only

  • Neither P1 nor P2
