Problem 7 (15 points) For each of the following propositions in the context of a C program, indicate if they are true or false. If false, give a counterexample. Assume that the variables are declared as follows: int x, y; 32 bit integers unsigned u; //32 bit unsigned integer and initialized to some unknown values. We have given the first answer as an example. True/False Counterexample If x> 0 then x1>0 01. 110..0 which is negative False 1#x > 0, x*x>0 If x x u>= 0 Ifx > y then -x
