c++ - C++编译器错误，从单词中删除字母

Question

编译器显示此错误:

error: invalid operands to binary expression ('basic_ostream<char, std::__1::char_traits<char> >' and 'void')

我究竟做错了什么？

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

void remove(string x, string y)
{
   while (x.find_first_of(y) != -1)
   {
      x.erase(x.find_first_of(y), 1);
   }
}

int main()
{
   string a, b;
   cout << "Enter word: ";
   cin >> a;
   cout << "Sign: ";
   cin >> b;
   cout << "Result: " << remove(a, b) << endl;

   return 0;
}

Answer 1

该函数不返回任何内容(即void)。所以你什么都不输出

写

string remove(string x,string y){
..............
return x;
}
