What is the output of the following code fragment int i 1 i

What is the output of the following code fragment?

int i = 1;

int sum = 0;

while (i <= 11)

{

   sum = sum + i;

   i++;

}

cout << \"The value of sum is \" << sum;

1)The value of sum is 0

The value of sum is 45

3)The value of sum is 55

ThThe value of sum is 66

Solution

Answer: The value of sum is 66

After executing this code, it will print sum value as 66

At line 1 i value is 1

and at 2nd line, sum vallue is 0

at line3, whle loop will run up to i value 11

inside while loop we are adding each value of i from 1 to 11 to sum.

at iteration i=1: sum = 1

at iteration i=2: sum = 3

at iteration i=3: sum = 6

at iteration i=4: sum = 10   

at iteration i=5: sum = 15   

at iteration i=6: sum = 21   

at iteration i=7: sum = 28   

at iteration i=8: sum = 36   

at iteration i=9: sum = 45   

at iteration i=10: sum = 55   

at iteration i=11: sum = 66
