negating characters in C

Solution
The two's complement of -128 in an 8-bit signed value is -128.
Look at the binary values:
Original value: 10000000
Complement: 01111111
Increment: 10000000
Problem
Is this undefined behavior? It prints `-128` as the result: ``` #include<stdio.h> int main() { char i=-128; i=-i; printf("%d",i); } ``` Please explain.
