大神救命啊，老是出现undefined reference 但是又找不到错误的原因

//main.cpp

/* run this program using the console pauser or add your own getch, system("pause") or input loop */
using namespace std;
double Account::annual=0.03;

saver1.calculate();
cout<<"saver1的月息 "<<saver1.getMinterest()<<" saver1的账户余额"<<saver1.getSavings()<<endl;

这是我写的课本上的一个有关于账户的一个类，在调用modify();时老发生错误，我用dev运行的，但是我前面已经声明定义过了啊，不知道为什么他老是给我13 C:\Users\tomienn\Desktop\第三题\main.cpp undefined reference to `Account::Modify(double)'这样的错误

你定义的不是类成员函数 void Account::Modify(double number) { Account::annual=number/100; }
