The output of the given code is 21.
Explanation:
int num = 12;
int x = 20
while (num <= x)
12<=20 13<=20 14 <= 20 15 <= 20 16 <=20 17 <=20 18 <=20 19 <=20 20 <= 20
{
num = num + 1; num = 13 num= 14 num= 15 num=16 num= 17 num= 18 num= 19 num= 20 num= 21
if (num*2 > x+num)
{ 26 > 32 28>34 30> 36 32> 36 34> 37 36> 38 38> 39 40> 40 42> 41
console.log(num);
} }
So this above output happens while you execute the given code, hence the output will be 21.
Because, when the num is 20, the execution goes like the following:
while(num<=x) while (20 <=12) {
20= num+1 (20+1) =21
if(num*2> x+num)
if (42 > 41)
{ console.log(21))}
