当我不调用命名函数[重复]时,“没有匹配的函数可供调用”

我不知道发生了什么。我需要在明天午夜前完成这项工作,但无论出于什么原因,它都行不通。

这是我试图编译的代码:

#include <iostream>
#include <cstdlib>
#include "heart.h"

Heart::Heart(int v){
SetValue(v);
SetColor("red");
SetSuit('H');
}
string Heart::Description() const   
// Good ol' fashioned copy-n'-paste...
// You know you love it.
{
  string d = "Value = ";    // temporary variable used to accumulate result
int Value = GetValue(); // A bit more complicated than I expected, but only a line's worth of difference after debugging.
  switch (Value)            // Append card value to variable's value
  {
    case 2:   d = d + "2";    break;      // Number cards
    case 3:   d = d + "3";    break;
    case 4:   d = d + "4";    break;
    case 5:   d = d + "5";    break;
    case 6:   d = d + "6";    break;
    case 7:   d = d + "7";    break;
    case 8:   d = d + "8";    break;
    case 9:   d = d + "9";    break;
    case 10:  d = d + "10";   break;
    
    case 11:  d = d + "J";    break;      // Face cards
    case 12:  d = d + "Q";    break;
    case 13:  d = d + "K";    break;
    case 14:  d = d + "A";    break;

    default:  d = d + "?";    break;      // Unknown card
  }
d = d + ", Color = " + GetColor(); // Hm, hm...
d = d + ", Suit = " + GetSuit(); // Further than that, the suits were ALSO copy-pasted from the color-cards, in their entirety!!
  return d;                 // Return string describing card value
}

请忽略这些评论,我这样做是为了大学课堂。 在编译过程中,我遇到了以下错误:

g++ -c heart.cpp
heart.cpp: In constructor ‘Heart::Heart(int)’:

此文件中没有对RedCard的调用,所有这些都在单独的文件中。 以防万一,这是心脏。h
