第9周 利息计算系统！
#include<iostream>using namespace std; int main() { int type, days; double money, period, rate, interest; //“period”？往下看就了然了！cout <<endl;cout << " ========欢迎使用利息计算系统！========= " << endl << endl;cout << " 请选择下列业务的相应代号" <<endl; cout << " =======================================" << endl;cout << " 1.活期储蓄" << endl;cout << " 2.三个月" << endl;cout << " 3.六个月" << endl;cout << " 4.一年" << endl;cout << " 5.二年" << endl;cout << " 6.三年" << endl;cout << " 7.五年" << endl;cout << " =======================================" << endl << endl;cout <<" 您选择的业务代号为："; cin >> type ; if (type>=1 && type <=7) { switch(type) { case 1: cout << " 请输入存款天数："; cin >> days; rate = 0.005; period = days /360.0; //豁然开朗！此处的“period”用得相当高明啊。解决了我很苦恼的一个问题。跪了！ break; case 2: rate = 0.031; period = 0.25; break; case 3: rate = 0.033; period = 0.50; break; case 4: rate = 0.035; period = 1.0; break; case 5: rate = 0.044; period = 2.0; break; case 6: rate = 0.050; period = 3.0; break; case 7: rate = 0.055; period = 5.0; break; } cout << " 请输入您的存款金额：￥"; cin >> money ; interest = money * rate * period; cout << " 您的利息为：￥"<< interest << "本息合计￥" << interest+money <<endl; cout << " 谢谢您的使用，欢迎下次光临！"<<endl; } else cout << " 你选择的业务代号有误，请确认后再次输入。"<<endl; //其实再输入就木有了。。 return 0; }
