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.

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.
