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 _________________.
