I have the same tasks(I presume we even go to the same class, OP) And I've solved all the tasks up to the 9th... The book is so general that it hurts and I can't seem to find some functions that help me shift between binary and 10-digit.
There seem to be some problems with compiling anything but main, but I'm going to ignore that for the sake of braintwisting.
Any hints on the 9th task guys?

My answers so far is this.

I know most, if not all answers here is wrong. But I hope to get an input of what i have done wrong, and maybe explain why my answer is wrong.

Problem 1
3 is the decimal number, ‘3’ Refers to the ASCII value of 3, and


The first part is correct. I don't think that's what they are going for on the second part. I think they are really asking what is the difference between '3' and "3", but the variable (3 in this case) can be replaced with anything. There is a distinct difference between single quotes and double quotes.

I'm actually a bit curious about problem 9 myself. Is counting the times you have to shift the value to the right, to get it to be equal to one, the correct way?

Yes, but you have to be careful. The first 1 you encounter is not likely to be the right bit. Look at the example number - if you return the position of the first bit set to 1, you're gonna be wrong. You can do it one of two ways

1) Start at the highest bit and shift right until you hit the first 1, then return that.
2) Start at the lowest bit and shift left until you hit the last 1, then return that.

Make sure you handle the case where n = 0.
