scanf/printf做法

#include<cstdio>
int main()
{
    int n;
    scanf("%d",&n);
    printf("%d ano(s)\n",n/365);n%=365;
    printf("%d mes(es)\n",n/30);n%=30;
    printf("%d dia(s)\n",n);
    return 0;
}

cin/cout做法

#include<iostream>
using namespace std;
int main()
{
    int n;
    cin>>n;
    cout<<n/365<<" ano(s)"<<endl;
    cout<<n%365/30<<" mes(es)"<<endl;
    cout<<n%365%30<<" dia(s)"<<endl;
    return 0;
}
