Coding Help

over 8 years

I'm going to post here when I can't figure out certain aspects of Java. I don't know how many of you know the language well, but help will be appreciated as I go through this bootcamp.

Also an excuse for me to post a countdown until Doomsday.

Oksus says

int main()
{
int x;
cin >> x;

for (x > 20; x++)
{
cout << x;
}

return 0;
}
and if i dont decalre it in the loop, like this, the code wont run at all.
This is why i need help xD

can't you do for(x=x; x>20; x++)

you should note that if x is greater than 20, then you have an infinite loop.

You have to declare the variable type before you assign it? In Java it would be int x = System.in or whatever, but I don't see how it would run because I would think the compiler would break at int x since it's not doing anything but declaring the type rather than assigning a value.

Because I have to declare x before I cin>> x; and I want to do it outside the loop

Why are you declaring x twice? You're instantiating it once outside of the loop and then again in the scope of the loop.

int main()
{
int x;
cin >> x;

for (int x; x > 20; x++)
{
cout << x;
}

return 0;
}

Can you show me the code? Can't really give advice without seeing it.

deletedover 8 years

there is, but for some reason when I do it, the code doesnt work the way it should.
Only happens in a for loop

Togepi says

I don't write C++, but is cin >> user input?

yes

Is there no way to assign the input to a variable and call it in the loop with that?

I am a loop master.

Mind explaining the For loop to me in c++.
I have this problem where i cannot get it to work unless i specify the value before.
If I want to input the value using cin >>, for some reason it won't register properly in the for loop.
