void fn_a( int& times, int& finish )
改为 void fn_a( int times[], int& finish ) fn_a( *times, *finish ); 改为 fn_a( times, finish ); 我按照题意写了一个，没发提交，所以不知道对或错  程序代码：#include <iostream> #include <limits> #include <algorithm> #include <utility> using namespace std; int main( void ) { size_t n; cin >> n; cin.ignore( std::numeric_limits<std::streamsize>::max(), '\n' ); pair<char,size_t> buf[26]; generate_n( buf, 26, [c='A']()mutable{return make_pair(c++,0);} ); for( char c; n!=0 && cin.get(c); ) { if( c>='A' && c<='Z' ) ++buf[c-'A'].second; else if( c>='a' && c<='z' ) ++buf[c-'a'].second; else if( c == '\n' ) --n; } auto p = remove_if( buf, buf+26, [](const auto& e){return e.second==0;} ); sort( buf, p, [](const auto& a, const auto& b) { if( a.second > b.second ) return true; if( a.second < b.second ) return false; return a.first < b.first; } ); for_each( buf, p, [](const auto& e){cout<<e.first<<' '<<e.second<<'\n';} ); } |

#include<iostream>
using namespace std;
void fn_a( int& times, int& finish )
{
int maxv=0;
char alpha[26]{ 'A','B','C','D','E','F','G','H','I','J','K','l','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z' };
for( int i=0; i<26; ++i )
if( maxv<times[i] ) maxv=times[i];
for( int i=0; i<26; ++i ){
if( times[i]==maxv ) cout << alpha[i] << ' ' << times[i] << endl;
times[i]=0;
finish++;
}
}
int main()
{
int n;
while( cin>>n ){
int times[26];
for( int i=0; i<26; ++i ) times[i]=0;
string sum="";
for( int i=0; i<n; ++i ){
string s;
cin >> s;
sum+=s;
}
int length=sum.length()-1;
for( int i=0; i<length; ++i ) times[sum[i]]++;
int finish=0;
while( finish<=26 )
fn_a( *times, *finish );
}
return 0;
}
编译器给的错误是什么意思啊?????!!!!!!
