    copied!<p>I'm relatively new to C++, and having an issue passing a string. I have 2 constructors for a class, Transaction." One constructor accepts a string and a double as its parameters, while the other accepts just a string.</p> <p>When I attempt to pass the lines below, I get an error, saying:</p> <pre><code>no matching function for call to 'Account::addTransaction(const char [14])' </code></pre> <p>or</p> <pre><code>no matching function for call to 'Account::addTransaction(const char [11], double&amp;)' </code></pre> <p>I know that there's no matching function, because I'm passing a string! Here's what I'm passing in:</p> <pre><code>bank.getAccount(index).addTransaction("Close Account"); bank.getAccount(index).addTransaction("Withdrawal", amount_to_withdraw); </code></pre> <p>I don't know how to make it any more explicit that the first parameter is a string. Any advice would be greatly appreciated.</p> <p>Thanks, Adam</p> <p>Updating per @g24l 's request:</p> <p>Here is the Transaction Class:</p> <pre><code>#ifndef TRANSACTION_H #define TRANSACTION_H #include &lt;iostream&gt; #include &lt;string&gt; using namespace std; class Transaction { private: string transType; double transAmount; /* public constructors: * 1st constructor is the default constructor * 2nd constructor is for non-monetary transactions * 3rd constructor is for transactions involving money */ public: Transaction() { transType = ""; } Transaction(string tType) { transType = tType; } Transaction(string tType, double tAmount) { transType = tType; transAmount = tAmount; } void setTransType(string); void setTransAmount(double); string getTransType() const; double getTransAmount() const; }; #endif /* TRANSACTION_H */ </code></pre> <p>In the Account class, which uses dynamic memory allocation for an array of transactions, I have:</p> <pre><code>class Account{ private: Depositor depositor; int accountNum; string accountType; double accountBalance; string accountStatus; Transaction *transptr; int numTransactions; //number of transactions public: // public member functions prototypes // Constructors /* Account default constructor: * Input: * Depositor() - calls the default depositor constructor * Process: * sets object's data members to default values * Output: * object's data members are set */ Account() { //cout &lt;&lt; "Account default constructor is running" &lt;&lt; endl; Depositor(); accountNum = 0; accountType = ""; accountBalance = 0.0; accountStatus = "open"; transptr = new Transaction[100]; numTransactions = 0; } </code></pre> <p>I'm wondering if, when I declare the array of Transactions, it fills in all of the Transactions with the default constructor parameters. When I "add" a transaction I'm really writing over the existing transaction.</p>
