“没有与参数列表相匹配的构造函数实例”

我使用的IDE是visual studio2019.
现我定义了一个学生类student。并且完成了构造函数与析构函数的声明和定义。但我在主函数调用构造函数时,编译器报错:“没有与参数列表相匹配的构造函数实例”。
编译器报错显示:主函数中的student stu(1,"wang",18,86)中的“1”没有与参数列表相匹配的构造函数实例

以下是我的代码

#include<iostream>
using namespace std;
class student
{
private:
    int id;
    char* name;
    int age;
    float score;
public:
    student(int i, char* n, int a, float s);
    student(student&);
    ~student();
    void printstu();
};
student::student(int i, char* n, int a, float s)
{
    cout << "constructing..." << endl;
    id = i;
    name = new char[strlen(n) + 1];
    age = a;
    score = s;
    if (name != 0)
    {
        strcpy(name, n);
    }
}
student::student(student&s)
{
    cout << "copy constructing..." << endl;
    id = s.id;
    age = s.age;
    score = s.score;
    name = new char[strlen(s.name) + 1];
    if (name != 0)
    {
        strcpy(name, s.name);
    }
}
student::~student()
{
    cout << "destructing..." << endl;
    delete[]name;
    name = 0;
}
void student::printstu()
{
    cout << "学号:" << id << "姓名:" << name;
    cout << "年龄:" << age << "成绩:" << score << endl;
}
void main()
{
    student stu(1, "wang", 18, 86);
    stu.printstu();
}

请教解答,orz

是不是因为第四个参数类型没对上,输入整型,构造函数是浮点型
