初學者C++程序中的分數組件

Question

我正在做一個任務，我應該編寫一個程序來測試用戶的數學技能。這裏是我現在的代碼：

using namespace std; 
void addition() 
{ 
    int Value, Value2, Answer; 
    bool gotAnswer; 

    for (int i=1; i<=10; i++) 
    { 
     Value = 1 + (rand()%10); 
     Value2 = 1 + (rand()%10); 

     gotAnswer = false; 
     cout << Value << " + " << Value2 << " = "; 

     for (int a=1; (a<=3 && gotAnswer==false); a++) 
     { 
      cin >> Answer; 
      if (Answer==(Value+Value2)) 
      { 
       cout << "CORRECT" << endl << endl; 
       gotAnswer = true; 
      } 
      else 
      { 
       cout << "WRONG Try again." << endl; 
       if (a==3) 
       { 
        cout << "You have missed 3 times. The answer is " << Value+Value2 << "." << endl << endl; 
       } 
      } 
     } 
    }  
} 

void substraction() 
{ 
    int Value, Value2, Answer; 
    bool gotAnswer; 

    for (int i=1; i<=10; i++) 
    { 
     Value = 1 + (rand()%10); 
     Value2 = 1 + (rand()%10); 

     gotAnswer = false; 
     cout << Value << " - " << Value2 << " = "; 

     for (int a=1; (a<=3 && gotAnswer==false); a++) 
     { 
      cin >> Answer; 
      if (Answer==(Value-Value2)) 
      { 
       cout << "CORRECT" << endl << endl; 
       gotAnswer = true; 
      } 
      else 
      { 
       cout << "WRONG Try again." << endl; 
       if (a==3) 
       { 
        cout << "You have missed 3 times. The answer is " << Value-Value2 << "." << endl << endl; 
       } 
      } 
     } 
    } 
} 

void Multiplication() 
{ 
    int Value, Value2, Answer; 
    bool gotAnswer; 

    for (int i=1; i<=10; i++) 
    { 
     Value = 1 + (rand()%10); 
     Value2 = 1 + (rand()%10); 

     gotAnswer = false; 
     cout << Value << " x " << Value2 << " = "; 

     for (int a=1; (a<=3 && gotAnswer==false); a++) 
     { 
      cin >> Answer; 

      if (Answer==(Value*Value2)) 
      { 
       cout << "CORRECT" << endl << endl; 
       gotAnswer = true; 
      } 
      else 
      { 
       cout << "WRONG Try again." << endl; 
       if (a==3) 
       { 
        cout << "You have missed 3 times. The answer is " << Value*Value2 << "." << endl << endl; 
       } 
      } 
     } 
    } 
} 

int main() 
{ 
    int number; 

    cout << "Enter the number for the problem type desired:"<<endl; 
    cout << " 1. Addition"<<endl; 
    cout << " 2. Subtraction"<<endl; 
    cout << " 3. Multiplication"<<endl; 

    cin >> number; 

    if (number == 1) 
    { 
     addition(); 
    } 
    else if(number == 2) 
    { 
     substraction(); 
    } 
    else if (number ==3) 
    { 
     Multiplication(); 
    } 
} 

該程序運行正常。但是，應該有一個評分組成部分，用戶在第一次嘗試中得到10分，在第二次嘗試中得到5分，在第三次嘗試/錯誤時得到0分。我不知道如何在10個問題的末尾融合得分組件和顯示。請提示一下？

所有在此先感謝。

Answer 1

您應該在每個函數中保留一個得分變量，根據需要添加到得分變量中，然後返回得分變量。

所以這些功能不再是空洞的，它們將是整數。然後您可以在最後得到分數並打印出來。

我不會爲你寫任何代碼，因爲它是作業：P
