銀行賬戶計劃構建和入門的問題

Question

到另一個程序。這是一個模擬銀行賬戶的程序。我需要幫助顯示餘額，提取和存款。如何在退出/存款後顯示最終餘額？

#include <iostream> 
#include <string> 
#include "BACCOUNT.H" 

    using namespace std; 
    int main() 
    { 
     double amount = 0.0; 
     double withrdraw = 0.0; 
     double deposit = 0.0; 
     string name; 
     double startamount = 100.00; 
     double balance = 0.0; 


     cout << "name: "; 
     cin >> name; 

     cout << "initial balance: " << startamount <<endl; 


     cout << "deposit? "; 
     cin >> amount; 
     cout << "withdraw? "; 
     cin >> amount; 


     cout << "balance for " << name << " is " << balance << endl; 

     system ("pause"); 

     return 0; 
    } 

Answer 1

cout << "balance for " << name() << " is " << balance() 
    <<endl; 

通過把括號後他們，你想打電話name和balance類似的功能，但他們string秒。刪除括號。

更重要的是，是什麼讓你認爲你不得不包括括號？可能存在一個基本的C++，你應該試圖完全理解你對（函數）的困惑。

Answer 2

您嘗試呼叫name和balance如下功能：

cout << "balance for " << name() << " is " << balance() <<endl; 
          ^^^^^^^    ^^^^^^^^^ 

但name是string和balance是double。此編輯將解決問題：

cout << "balance for " << name << " is " << balance <<endl;
