What is an unsigned int in c?

Question

I have some code that I have to study and I'm not understanding what is a unsigned int and how it works.

void print_all_sums(unsigned int n,double a[n])
{ // 1 <= n <= 30
   unsigned int i,j,mask;
   double s;

Something like this.

You did not show how that `unsigned int` is used. Please post the [Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve) that shows the problem. — Weather Vane, Nov 16 '17 at 19:07
You use it like you would any other value. Just that it with be either 0 or a positive number. — AntonH, Nov 16 '17 at 19:09
It represents what in mathematics is known as a "Natural Number". https://en.wikipedia.org/wiki/Natural_number. — Clifford, Nov 16 '17 at 19:18

An unsigned int in C is a data type which has a non-negative value. (Eg. 0,1,2,3,4...)

0 is also a valid value, but is not positive. – AntonH Nov 16 '17 at 19:08
I tried it in a simple code and 0 works as unsigned int. Thanks for the help @AntonH. – Nacev Nov 16 '17 at 19:09
