Thread: Help me understand the logic of the code?

If anyone can, Please help me out understand the logic of the code and most likely how it works. I was able to come up with it somehow but without knowing proper back processing, It is kinda weird to me. Just posting the part where it is confusing. And it is about counting the digits in entered number(I gave count value of 0 before hand already).

Code:

 
for(;n<0;)
{
count=count+1;
n=n/10;
}

would you understand it?

By the way, I think you have a typo: n < 0 probably should have been n > 0

I meant the process that goes in the background to understand the language better.
Also, You had put up a valid typo. Now I just checked, I just made mistake when typing the code in hurry. A silly mistake.

Ah, I understand what you mean. I will do that. Thanks.
