In the following code:

#include

int main(void){ char c; unsigned char uc; c = uc = 90; c = 2*c; uc = 2*uc; printf("%d ", c); printf("%d ", uc); return 0; }

Can someone please explain to me why -76 would be the first printed output and why 180 would be the 2nd printed output?

Please explain in detail.
