请大家帮我看下

[青草渐枯黄]

#include<iostream>
#include<string>
using namespace std;
void echo(string message)
{

strcat(message," you");
cout<<message<<endl;
}


void main()
{
string word;
cout<<"enter your word:";
cin>>word;
echo(word);
}
我的用意是希望通过调用echo函数，在echo函数中，做字符的连接操作，请各位不吝赐教~~~

void echo(string message)
{
message.append("you");
cout < <message < <endl;
}

strcat(char* s,char* t)参数都是char*的。不要混淆char* 和 string。

用这个试试：
void echo(string message)
{

message.append(" you");
cout < <message < <endl;
}

#include <iostream> 
#include <string> 
using namespace std; 

void echo(string message) 
{ 
    message += "you";
    cout <<message <<endl; 
} 


void main() 
{ 
    string word; 
    cout<<"enter your word:"; 
    cin>> word; 
    echo(word); 
} 

[HelloDan]

#include <iostream>
#include <cstring>

using namespace std;

void echo(char* message)
{
  
  strncat(message,"you",4);
  cout <<message <<endl;
}


int main()
{
  char word[100];
  cout <<"enter your word:";
  cin>>word;
  echo(word);
  return 0;
}

同意楼上的关点

[dzw0123]

#include "stdafx.h"
#include "iostream.h"
#include "string.h"

void echo(char* message)
{

strncat(message,"you",4);
cout <<message <<endl;
}


void main()
{
char word[100];
cout <<"enter your word:";
cin>>word;
echo(word);
}
这样调试可以成功！
