Where is my execution timed out?

Question

I know that execution timed out means that there is an endless loop but I can’t find where. I’m doing the snail in the well project. Here is my code:
function main() {
var depth = parseInt(readLine(), 10);
var days=0
var x=0
do{
x+7
}
while (x<depth){
x-2
days++
}

}

Thx

Answer 1

it's either a while loop, or a do..while:

while (cond) {}

or:

do {} while (cond);

the difference is when cond(itional) expression is evaluated ;)

Answer 2

Have you figured out why the infite loop is happening ElizabethM ? As visph has said, your syntax is a bit off. I think the the infinite loop is because you're not incrementing x. I.e. You're adding 7 but not saving that new value to x. So you probably want x = x+7, or you could do x += 7.
