C++的IO操作
#include <iostream>
using namespace std;
int main()
{
char name[20];
char gender;
int age;
cout << "请输入姓名、性别(M/F)和年龄:"<<endl;
cin >> name >> gender >> age;
cout << "name :"<<name <<endl;
cout << "sex:"<<gender <<endl;
cout << "birthday:"<<2014-age<<endl;
using namespace std;
int main()
{
char name[20];
char gender;
int age;
cout << "请输入姓名、性别(M/F)和年龄:"<<endl;
cin >> name >> gender >> age;
cout << "name :"<<name <<endl;
cout << "sex:"<<gender <<endl;
cout << "birthday:"<<2014-age<<endl;
}
ot@embedded c++]# g++ name.cc
[root@embedded c++]# ./a.out
请输入姓名、性别(M/F)和年龄:
张三 M 22
name :张三
sex:M
birthday:1992
[root@embedded c++]#
假设年龄小于0怎么办呢?
{
char name[20];
char gender;
int age;
cout << "请输入姓名、性别(M/F)和年龄:"<<endl;
cin >> name >> gender >> age;
cout << "name :"<<name <<endl;
cout << "sex:"<<gender <<endl;
if(age>=0)
cout << "出生年份:"<<2014-age<<endl;
if(age <0)
{
cout << "你来自未来??"<<endl;
cout <<"出生于"<<-age<<"年之后!"<<endl;
}
}
t@embedded c++]# ./a.out
请输入姓名、性别(M/F)和年龄:
机器猫 M -10
name :机器猫
sex:M
你来自未来??
出生于10年之后!
