GATE 2019 - The number of times printf statement is executed is:

Question

int main()
{
float sum, i = 1.0, j = 2.0;
while (i/j > 0.0625)
{
j = j + j;
printf("%f", i+j);
}
}

The number of times printf statement is executed is:

Comments

5 times

---

I think i=2 and j=1

---

As far as current program snippet is concerned , it will be 3.

But in gate 2019 , the values were swapped.

Answer 1

According to the above example, the loop will run 5 times as the values of i/j is 0.5, 0.25, 0.125 and 0.0625

respectively. But in the actual GATE 2019 question the values were swapped and according to that, the loop will run 3 times.

Answer 2

In the current question, printf will be executed 3 times.

In Gate 2019 question paper however, the original question was:

int main()
{

  float sum = 0.0, j = 1.0, i = 2.0;
  while (i / j > 0.0625)

  {

    j = j + j;

    sum = sum + i/j;
    printf("%f\n", sum);

  }

}

In the above scenario, printf will be executed 5 times
