请问这个程序错在哪里?谢谢

#include <iostream.h>
class Person
{
private:
char Name;
int Age;
int Height;
int Weight;
public:
Person(char name, int age, int height, int weight);
printPerson();
}

Person::Person(char name,int age,int height,int weight)
{
Name = name;
Age = age;
Height = height;
Weight = weight;
}

Person::printPerson()
{
cout << Name << Age << Height << Weight << endl;
return 0;
};

main()
{
Person('L',23,171,60);
printPerson();
return 0;
}
编译器给的错误信息是:Function 'printPerson' should have a prototype

这样测试才对

main()
{
Person person1('L',23,171,60);
person1.printPerson();
return 0;
}

成员函数printPerson没有返回类型

[lingye]

是的，要先定义一个penson类的
Penson p('L',23,171,60);
p.printPerson();

类的声明最后没有;可能楼主笔误

#include <iostream>
using namespace std;

class Person {
private:
char Name;
int Age;
int Height;
int Weight;
public:
Person(char name, int age, int height, int weight);
void printPerson();
};

Person::Person(char name,int age,int height,int weight) :
Name(name), Age(age), Height(height), Weight(weight)
{
}

void Person::printPerson()
{
cout << Name << Age << Height << Weight << endl;
}

int main()
{
Person person('L', 23, 171, 60);
personprintPerson();
}

要声明一个具体的对象person1。然后对对象进行操作！
class Person
{
private:
char Name;
int Age;
int Height;
int Weight;
public:
Person(char name, int age, int height, int weight);
int printPerson();
};

Person::Person(char name,int age,int height,int weight)
{
Name = name;
Age = age;
Height = height;
Weight = weight;
}

Person::printPerson()
{
cout << Name << Age << Height << Weight << endl;
return 0;
}

int main()
{
Person Person1('L',23,171,60);
Person1.printPerson();
return 0;
}
