C++作业2

1、标准体重

#include <iostream>
using namespace std;
int main()
{
double h,m,x;
cout<<"请输入身高,体重：h,m";
cin>>h>>m;
x=h-100;
if(m>1.2*x)
cout<<"超重";
else if(m<0.8*x)
cout<<"超轻";
}2、分段函数求值
#include <iostream>
using namespace std;
int main()
{
int x,y;
cout<<"输入x";
cin>>x;
if(x>=1)
{
y=x-1;
cout<<y;
}
else
{
y=1-x;
cout<<y;
}
} 3、模拟ATM
#include <iostream>
using namespace std;
int main()
{
int m,n;
cout<<"张氏银行欢迎您"<<endl;
cout<<"请输入密码:";
cin>>m;
if(m==123456)
{
cout<<"1.查询"<<endl;
cout<<"2.取款"<<endl;
cout<<"3.存款"<<endl;
cout<<"4.转账"<<endl;
cout<<"o.退出"<<endl;
cout<<"请选择功能类型:";
cin>>n;
if(n==1)
cout<<"查询";
if(n==2)
cout<<"取款";
if(n==3)
cout<<"存款";
if(n==4)
cout<<"转账";
if(n==0)
cout<<"退出";
}
else
cout<<"对不起，您的密码有误";
return 0;
}
