A while loop that loops 7 times and prints out: 2 4 6 s 10 12 14. A do while loop that loops 6 times and prints out: 1 2 3 4 5 6 A for loop that loops 7 times and prints out: 1 4 9 16 25 36 49.Explanation / Answer

* how many times does the following loop execute and why?
for(i=0;i<10;i++){
//loop body
}
Ans-
for loop execute 10 times
because in that i=0.this value less than 10 so loop will be begin than i++ so i value=2 this also less than 10 so agin loop will be begin .the loop will stop when i reach value 10 because 10<10 is false .
var k=12;
while(k>7){
document.write(k+"th item.");
k=k-1;
}
Ans-
Output will be generate
12th item
11th item
10th item
9th item
8th item
Because k=12 when loop start k>7(12>7) so loop will be begin output will be printed
K=k-1 so k=11 this also less than 12 so again output will be printed
The loop will be ended then k=7 because7>7 is false.
do
{
responce=prompt("enter password", " ");
}
while(responce!="gamecooks")
Ans-
In javascript prompt is user input .
Input will be assign to responce variable
This loop will be continue until responce!="gamecooks"
If responce="gamecooks" then loop will stop

Var i=1;
do{
document.write(i);
i++
}while(i<7)
</script>
4)

for(i=1;i<=8;i++){
document.write(Math.pow(i,2));
}
