Question
Consider the following C program:The number of times the variable sum will be printed, when the above program is executed, is ______.
#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;
}
Correct answer
5 to 5
Solution
To find the number of times the
Condition:
printf statement is executed, we trace the while loop iterations:Initial values: , , .Condition:
1.Iteration 1:
- Check condition: (True)
-
printfexecuted (1st time)
- Check condition: (True)
-
printfexecuted (2nd time)
- Check condition: (True)
-
printfexecuted (3rd time)
- Check condition: (True)
-
printfexecuted (4th time)
- Check condition: (True)
-
printfexecuted (5th time)
- Check condition: (False)
- The loop terminates.
sum is printed is 5.Continue learning with Success Tracker
