巧妙地在于定义一个string数组

#include<bits/stdc++.h>
using namespace std;
string a[50]={
"zero","one","two","three","four","five","six","seven","eight","nine","ten","eleven",
                "twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen","twenty",
                "thirty","forty","fifty"};
void f(int num)
{
    int p=num/10;
    int q=num%10;
    if(num<=20)
        cout<<a[num];
    else
    {
        cout<<a[p+18];//利用数组
        if(q!=0)
            cout<<" "<<a[q];
    }
}
void ft(int h,int m)
{
    f(h);
    cout<<" ";
    if(m==0)
        cout<<"o'clock"<<endl;
    else
    {
        f(m);
        cout<<endl;
    }
}
int main()
{
    int h,m;
   scanf("%d%d",&h,&m);
   ft(h,m);
   return 0;
}
