Comparison operation on unsigned and signed integers

Question

See this code snippet

int main()
{ 
 unsigned int a = 1000;
 int b = -1;
 if (a>b) printf(\"A is BIG! %d\\n\", a-b);
 else printf(\"a is SMALL! %d\\n\", a         


        

Answer 1

Find a easy way to compare, maybe useful when you can not get rid of unsigned declaration, (for example, [NSArray count]), just force the "unsigned int" to an "int".

Please correct me if I am wrong.

if (((int)a)>b) {
    ....
}
