如何將變量放入數組

我製作的籃球記分牌可以確定每個季度的遊戲勝者和主遊戲。如何將我的變量的值存儲在數組中？我想將「Q1teamOne，Q2teamOne，Q3teamOne，Q4teamOne」的值放在一個數組中，並且還要將「Q1teamTwo，Q2teamTwo，Q3teamTwo，Q4teamTwo」的值或它們作爲數組的元素。如何將變量放入數組

#include <iostream> 
#include <string>

int Q1teamTwo, Q2teamTwo, Q3teamTwo ,Q4teamTwo; 
int Q2TeamOneTotal, Q3TeamOneTotal, Q4TeamOneTotal; 
int Q2TeamTwoTotal, Q3TeamTwoTotal, Q4TeamTwoTotal; 
double teamOneScore[4]; 
double teamTwoScore[4]; 
int index; 
double sumOne, sumTwo; 

cout << "BASKETBALL SCOREBOARD:\n" << endl; 
cout << "Enter Team 1 name: "; 
getline (cin, Team1);

'std :: array teamOneArray;'？你已經擁有了數組的分數，這意味着你已經知道如何創建數組了，那麼你的問題是什麼？ – 2014-12-02 08:34:06

是的我知道如何創建數組，但是我如何將變量值放在「teamOneScore」數組中？ – 2014-12-02 08:56:53

你應該使用'vector'而不是數組。這是存儲集合的C++方式。 – 2014-12-02 09:21:18

什麼約：

teamOneScore [0] = Q1teamOne;

teamOneScore [1] = Q2teamOne;

teamOneScore [2] = Q3teamOne;

teamOneScore [3] = Q4teamOne;

teamTwoScore [0] = Q1teamTwo;

teamTwoScore [1] = Q2teamTwo;

teamTwoScore [2] = Q3teamTwo;

teamTwoScore [3] = Q4teamTwo;

但是考慮：

陣列teamOneScore和teamTwoScore是雙陣列和你的分數是整型，所以：

變化的數組類型是整數或
投轉讓as：teamOneScore [0] = static_cast < double>（Q1teamOne）;

而且，只爲您的信息，這種比較是不正確的：

否則，如果（Q4TeamOneTotal = Q4TeamTwoTotal）

它應該是：如果

其他（Q4TeamOneTotal == Q4TeamTwoTotal）

作爲最後一點，您可以使用數組來存儲cin的分數，並避免使用Q1teamOne，... vars。

我遵循你的建議，並使用cin存儲我的價值觀，感謝您的幫助！ – 2014-12-02 10:05:12

例如

#include <functional> 

//... 


std::reference_wrapper<int> teamOne[] = { Q1teamOne, Q2teamOne, Q3teamOne, Q4teamOne }; 

std::reference_wrapper<int> teamTwo[] = { Q1teamTwo, Q2teamTwo, Q3teamTwo ,Q4teamTwo };

下面是一個示範程序

#include <iostream> 
#include <functional> 

int main() 
{ 
    int Q1teamOne, Q2teamOne, Q3teamOne, Q4teamOne; 
    std::reference_wrapper<int> teamOne[] = 
    { 
     Q1teamOne, Q2teamOne, Q3teamOne, Q4teamOne 
    }; 

    int i = 0; 
    for (auto &x : teamOne) x.get() = i++; 

    for (const auto &x : teamOne) std::cout << x << ' '; 
    std::cout << std::endl; 

    return 0; 
}

程序輸出是

0 1 2 3

或者，如果原始值和所述陣列之間的鏈路不需要那麼喲你可以簡單地寫

double teamOneScore[] = { Q1teamOne, Q2teamOne, Q3teamOne, Q4teamOne };

你也可以在基於for語句的範圍中使用初始值設定項列表而不聲明任何數組。例如

for (int x : { Q1teamOne, Q2teamOne, Q3teamOne, Q4teamOne }) std::cout << x << ' '; 
std::cout << std::endl;
