类和对象

#include<iostream>
#include<string>

class Human
{
    public:
        string name;
        int age;
        
        void IntroduceSelf()
        {
            cout<<"I am" + name <<"and am";
            cout<<age<<"yeas old"<<endl;
        }
};
int main()
{
    //An object of class Human with atttibute name as "Adam
    Human firstMan;
    firstMan.name="Adam";
    firstMan.age= 30;
   
    //An object of class Human with attribuete name as "Eve"
    Human firstWoman;
    firstWoman.age=28;
   
    firstMan.IntroduceSelf();
    firstWoman.IntroduceSelf();
} 这是编译器出现的报错，代码都是照的书上代码敲的，也没有单词敲错啊，大神们能告诉我原因吗？编译器用的 Dev-C++ 5.11
