可以通过定义一个字符特征输出函数来实现输出，例如：

#include 
#include 

class Character {
private:
    std::string name;
    int strength;
    int agility;
    int intelligence;

public:
    Character(std::string name, int strength, int agility, int intelligence) :
        name(name), strength(strength), agility(agility), intelligence(intelligence) {}

    void printCharacteristics() const {
        std::cout << "Name: " << name << std::endl;
        std::cout << "Strength: " << strength << std::endl;
        std::cout << "Agility: " << agility << std::endl;
        std::cout << "Intelligence: " << intelligence << std::endl;
    }
};

int main() {
    Character character("John", 10, 8, 12);
    character.printCharacteristics();

    return 0;
}

在该示例中，定义了一个Character类来包含角色的属性，并定义了一个名为printCharacteristics的函数来输出这些属性。该函数将属性输出到控制台上，因此在主函数中调用该函数即可输出角色的属性信息。
