named_operator.cpp

Build and use custom infix-style operators. Demonstrates how make_named_operator can wrap callables and expose them through the custom infix syntax supported by GMP.

#include <gmp/gmp.hpp>
 
int main() {
    auto plus = gmp::make_named_operator([](int lhs, int rhs) {
        return lhs + rhs;
    });
 
    auto add_assign = gmp::make_named_operator([](int& lhs, int rhs) -> int& {
        lhs += rhs;
        return lhs;
    });
 
    int value = 10;
    const int result = value ^plus^ 5;
    value ^add_assign^ 7;
 
    return (result == 15 && value == 17) ? 0 : 1;
}
