实验二课后作业

项目一 标准体重

#include<iostream> 
using namespace std;
int main() 
{double h,w,a,b,c; cout<<"请输入您的身高（单位cm）及体重（单位kg）:n"; cin>>h>>w; a=<span style="font-family: Arial, Helvetica, sans-serif;">h-100; </span>b=a+(a*0.2); c=a-(a*0.2); if(c<=w&&w<=b) cout<<"您的体重是正常的n"; else if(w>b) cout<<"您偏重了";else cout<<"您偏轻了"; return 0;
}

项目三  两点之间的距离

#include<cmath>
#include<iostream>
using namespace std;
int main()
{double x1,y1,x2,y2,d;cout<<"输入<x1,y1><x2,y2>:n";cin>>x1>>y1>>x2>>y2;d=sqrt((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2));//cout<<"两点之间的距离:"<<d<<endl;return 0;
}

项目四  模拟ATM

#include<iostream>
using namespace std; 
int main() 
{ int code;
cout<<"HUAHUI银行欢迎您"<<endl;
cout<<"请输入密码:";
cin>>code;
if(code==970818) 
{cout<<"1.查询"<<endl;cout<<"2.取款"<<endl;cout<<"3.存款"<<endl;cout<<"4.转账"<<endl;cout<<"0.退出"<<endl;
}
else cout<<"密码错误请重新输入";
