}
}

b. function main()
{
var num;
var keepLooping = 1;
while (keepLooping = 1)
{

}
}
main();
c. function main()
{
var loopNum;
loopNum = Number(prompt("Enter the number of times to loop"));
var ctr = 1;
console.log(“The even numbers in the range entered are: “);
do
{
console.log(ctr);
ctr = ctr + 2;
}
while (ctr <= loopNum)
}
main();
d. function main()
{
ctr = 1;
do while (ctr <= 10)
{
console.log ("The value of ctr is " + ctr);
ctr = ctr + 1;
}
}

e. function main()
{
for (i=10; i > 0; i++)
{
