將字符打印爲std :: cout的數字

Question

我不明白我的問題在這裏。我的名單中關於派別和數量的價值看起來是正確的。但是，我的輸出有問題。給我唯一的數字和字母沒有在他們在什麼派系顯示

正在打印的號碼語句是在底部，像這樣的：

cout << "Your first Card is " 
    << numberBoxListHead_ptr->getNumber() 
    << factionHead_ptr->getLetter() 
    << endl; 

以下是完整的代碼：

#include <iostream> 
#include <conio.h>

//The Class where the List depends on it.

    int number;

public:

    void setNumber(int number) 
    { 
     this->number = number; 
    } 

    void setLetter(char letter) 
    { 
     this->letter = letter; 
    } 


    int getNumber() 
    { 
     return number; 
    } 

    char getLetter() 
    { 
     return letter; 
    } 
};

Answer 1

int getLetter() 

這是錯誤在這種情況下。 letter是一個字符，如果要將其作爲字母打印，請確保返回字符。

char getLetter() { ... } 

如果返回int，std::cout將打印就像它的牌點數它的數值。如果返回一個char，它將打印相應的字符，而不是其數字值。

（你的代碼需要一個嚴重的重構工作。讓函數來處理輸入的西裝，和排名，並重新使用這些功能，然後找出如何做一個循環讀取四張牌。）
