What is the output of the following program? function start () {var x = 5; sumTo (x); println (x); }function sumTo (num) {var sum = 0; for (var i = 0; i < = num; i++) {sum + = i; }println (sum); }

Output of the following code:-

5

15

Explanation:

There are two functions in the code given above.

function start () function sumTo (num)

start function is used to call the second function sumTo with variable x whose value is 5.

in function there is a for loop which runs from i 0 to num and adds up i to the sum. So the sum will be 15 when the argument is 5.

start function also prints the value of x and the sum is printed in the new line. So the output is

5

15.
