c - Comparison between unsigned int and int without using cast operator -

everyone looked around there exists topic question yet not find.

unsigned int x = 5;  int y = -3; if(y<x)    func1(); else    func2();

func2 called . want func1 called.

i know must use cast operator when comparing these values.
not allowed use cast operator or changing type of variable.

how can solve problem?

first check if y negative value, knowing that, know x bigger since unsigned.

if y not negative, compare value directly x. not think cause issue since there no negative sign present.

see below example:

if(y<0) {     //x>y     func1(); } else if (y<x) {     //lets y=3, , x=5     func1(); } else {     func2(); }
