Custom type traits enhance type manipulation in C++. They allow you to define characteristics of types. Using type traits enables conditional compilation. This leads to more generic and reusable code. Here’s an example:

“`cpp
#include
#include
using namespace std;
template
struct is_pointer {
static const bool value = false;
};
template
struct is_pointer {
static const bool value = true;
};
int main() {
cout << is_pointer::value; // Outputs 1
return 0;
}
“`

In this code, `is_pointer` determines if a type is a pointer. Custom type traits help tailor your templates effectively.
