Many programs assume sizeof(int)==sizeof(unsigned int) . IMO it is not and I cant find anything in the Standard which guarantees it. Am I right or wrong?
C11 6.2.5.6 (Types) says "For each of the signed integer types, there is a corresponding (but different) unsigned integer type (designated with the keyword unsigned) that uses the same amount of storage (including sign information) and has the same alignment requirements."
