Consider the following C program:

 `#include `` ` `int` `main() {`` ``float` `sum = 0.0, j = 1.0, i = 2.0;``  ` ` ``while` `(i / j > 0.0625) {``     ` `    ``j = j + j;``    ``printf``(``"%f\n"``, sum);`` ``};`` ``return` `0;``}`

The number of times variable sum will be printed When the above program is executed is _________ .

Note: This was Numerical Type question.
(A) 5
(B) 6
(C) 4
(D) 0

Explanation:

 `#include `` ` `int` `main() {`` ``float` `sum = 0.0, j = 1.0, i = 2.0;``  ` ` ``while` `(i / j > 0.0625) {``     ` `    ``j = j + j;``    ``printf``(``"%f\n"``, sum);`` ``};`` ``return` `0;``}`

According to “while” loop,

```Initially i = 2.0, j = 1.0
i / j = 2.0 / 1. 0 = 2.0 > 0.0625

j = j + j
j = 2.0
printed sum = 0.0

Second time,
i / j = 1 > 0.0625
j = 4
printed sum = 0.0

Third time,
i / j = 0.5 > 0.0625
j = 8
printed sum = 0.0

Fourth time,
i / j = 0.25 > 0.0625
j = 16
printed sum = 0.0

Fifth time,
i / j = 0.125 > 0.0625
j = 32
printed sum = 0.0

Sixth time,
i / j = 0.0625 = 0.0625
It violates the greater then condition.
This time while loop will not execute.```

So, option (A) is correct.
