My ans:4

Right=(3)

Answer 1

First write code completely u did one mistake in if condition u should write if(i==2)
When first time loop will execute i =0 and
var sum = 0;
Then we will check condition
0<5 which is true so inner part will be execute sum =0+0 becoz both are zero then check if condition
If(0==2) this is false then loop will run again here i will increase by 1 so i=1
1<5 condition true so inner will execute sum=i+sum =1+0 so sum =1 then we will check if condition ita false so loop value will increase again i=2 check condition 2<5 condition true so
So
sum=sum +i (sum=1 and i=2 )
sum=1+2=3 it will assign to sum then we check if condition i was 2
So if(2==2) condition true so loop will break and final
for (var i = 0; i < 5; i++) {
sum += i // sum=0+0 first time
if (i ==2)
{
break;
}
}console.log(sum);

final Output will be 3

Answer 2

Suberna Das what happened if u have any doubts u can ask here why u pasting my same answer in dm

Answer 3

for (var i = 0; i < 5; i++) {
sum += i:
}
See this loop will work total 5 times first time i=0 then we check condition
0<5 this is true then
sum+=i means sum=sum+i
sum=0+0 =0 so sum is 0 here now i is increase see third step of loop u write i++ so before i was 0 now i is 1
So sum+=i means sum=sum+ i
Sum was 0 and i =1
sum=0+1=1 and this will assign to sum =0 again third step i ++ now i will increase again so i=2
Next sum+=i which is sum=sum+i (sum=1 and i =2 )
Sum=3
Then if condition we check its true so break

Answer 4

It's not going to run. First fix syntax errors.

Answer 5

Sum =sum+i(sum=1, i=2)
Sum=1+2=3
"How value of sum reach to 1, because sum=0;is given.
You write also sum=0+0and1+0

Answer 6

Sum का मान 1 कैसे हो गया आपने तो पहले 0 लिखा था. समझा दीजिए प्लीज।
