unsigned modifier holds only positive value. Then why it gives something random positive integer on assigning -ve value?

Question

unsigned int a = -1;
gives 4294967295 which is max value of unsigned int and for -2 4294967294 basically starting reverse from max on -ve values. Explain?

Answer 1

Why so? I believe it's due to the effect of integer overflow 👇

Answer 2

`unsigned int` is 32bit integer with 0 as min value, and (2 ^ 32) - 1 as max value.

2 ^ 32 => 4.294.967.296

When you try to assign a negative value for an `unsigned int` variable, add the max value above by the negative value.

4.294.967.296 + (-1) => 4.294.967.295

4.294.967.296 + (-2) => 4.294.967.294

And so on ...
