Problem

Given a dictionary, ask again.

There is a blank line between the dictionary and the query.

Cin.peek () is a pointer to the current character.

#include <iostream> #include <string> #include <map>using namespace std;map<string, String>dic ; string s, T;int f;int main () {    ios::sync_with_stdio (false);    while (CIN >> s)        if (cin.peek () = = ' \ n ')//The pointer currently points to \ n            if (!f)            {                f = 1;                Dic[s] = t;//The current read in S is alien, the t just read into is the corresponding English            }            else                cout << ((t = dic[s])! = ""? T: "eh") << "\ n";        else//Description S is a dictionary of English        {            F = 0;//f=0 represents the next to be read outside the star            t = S;        }}

Tips for handling empty lines

#include <cstdio> #include <algorithm> #include <cstring>using namespace std; #define N 100005#define M 15char s[n];int c;struct mydic{    char zh[m];//outer star    char en[m];//English} dic[n];int cmp (const mydic &a, const Mydic & AMP;B) {    return strcmp (A.zh, B.zh) >= 0;} void  Solve () {    int l = 0, r = C;    while (L < R)    {        int m = r+l >> 1;        int f = strcmp (S, Dic[m].zh);        if (f = = 0)        {            printf ("%s\n", dic[m].en);            return;        }        if (F < 0)            L = m + 1;        else            r = m;    }    printf ("eh\n");} int main () {while    (gets (s))    {        if (!s[0]) break;//read to the empty line        sscanf (S, "%s%s", Dic[c].en,dic[c].zh);        C + +;    }    Sort (dic, DIC + C, CMP);    while (gets (s))        Solve ();}
