WebThe problem is that we have no type typ to check exp : typ . Solution 1: check exp with each of the four types. check Env => exp ; valid = try each typ in [bool,double,int,void]: check exp : typ. This is inefficient, and does not scale up to infinitely many types. Solution 2: do type inference with exp. WebHowever, if the type generic macro is implemented like this: #define is_const_int (x) _Generic ( (x), \ const int: "a const int", \ int: "a non-const int", \ default: "of other type") The output is: i is a non-const int j is a non-const int k is of other type.
