unsigned int

Question

What happens when I use unsigned int a and make it to negative?Does it stop at 0 or what?
F.x.
Int a=5;
Int b=7;
Unsigned int sum;
Sum=a-b

Answer 1

You cannot assign a negative value to an unsigned int. Here is an example

M means the maximum number of unsigned int

unsigned int n = 0-5;
cout << n; // prints M-4
unsigned int a = 0-1;
cout << a; // prints M
