Consider the following C program:

#include <stdio.h>
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);
}
return 0;
}

The number of times the variable sum will be printed, when the above program is executed, is _________

Initially

i = 2.0, j = 1.0

J = 1 => i/j = 2/1  > 0.0625 // First print

J = 1+1 => i/j = 2/2 > 0.0625 //second print

J = 2+2 => i/j = 2/4  > 0.0625// Third print

J = 4+4 => i/j = 2/8 > 0.0625 // fourth print

J = 8+8 => i/j = 2/16 > 0.0625 // Fifth print

J = 16+16 => i/j = 2/32 > 0.0625 (False)

$i = 2.0, j=1.0$

while $( \frac{i}{j} > 0.0625)$

$j = 1$
$\frac{i}{j} = \frac{2}{1} > 0.0625$
$j=j+j, 1^{st}$ PRINT

$j=2$
$\frac{i}{j} = \frac{2}{2} > 0.0625$
$j=j+j, 2^{nd}$ PRINT

$j=4$
$\frac{i}{j} = \frac{2}{4} > 0.0625$
$j=j+j, 3^{rd}$ PRINT

$j=8$
$\frac{i}{j} = \frac{2}{8} > 0.0625$
$j=j+j, 4^{th}$ PRINT

$j=16$
$\frac{i}{j} = \frac{2}{16} > 0.0625$
$j=j+j, 5^{th}$ PRINT

$j=32$
$\frac{i}{j} = \frac{2}{2} = 0.0625$
$Break$

Total $5$ times sum will be printed.

while loop condition is :-

$\frac{2}{2^{k}}> 0.0625$

this condition will be true for k=0,1,2,3,4 but fails for k=5

so it'll print sum 5 times.

5 times while loop will iterate..
