no matching constructors for initialization Qt - c++

Question

I am doing an Assignment on one of my Programming modules and im a bit stuck.
I keep getting the Error no Matching Constructors for initialization whenever i create an object of a certian class.
There might be some other errors to, im still busy with the setup of everything. Is my classes setup correctly?
SavingsAccount.h
#ifndef SAVINGSACCOUNT_H
#define SAVINGSACCOUNT_H
#include "transaction.h"
#include <QString>
#include <QList>
#include <QDate>
class SavingsAccount
{
public:
SavingsAccount (QString name, QString num);
~SavingsAccount();
QList<Transaction> addTransaction(Transaction T);
double totalTransactionCost();
QString frequentTransactionType();
QList<Transaction> transactionsOnAdate(QDate date);
QString toString();
private:
QString m_CustomerName;
QString m_AccountNumber;
QList<Transaction> m_TransactionList;
};
#endif // SAVINGSACCOUNT_H
SavingsAccount.cpp
#include "savingsaccount.h"
#include <QString>
#include <QList>
#include <iostream>
using namespace std;
SavingsAccount::SavingsAccount(QString name, QString num){
m_CustomerName = name;
m_AccountNumber = num;
}
SavingsAccount::~SavingsAccount(){
}
QList<Transaction> SavingsAccount::addTransaction(Transaction t){
}
QString SavingsAccount::frequentTransactionType(){
}
QString SavingsAccount::toString(){
}
double SavingsAccount::totalTransactionCost(){
}
QList<Transaction> SavingsAccount::transactionsOnAdate(QDate date){
}
Main.cpp
#include <QCoreApplication>
#include "transaction.h"
#include "savingsaccount.h"
#include <string>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
string accName;
int accNum;
cout << "Enter Account Name: "<< endl;
cin >> accName;
cout<<"Enter Account Number: " <<endl;
cin >> accNum;
SavingsAccount accholder1(accName,accNum);
return a.exec();
}
Thanks so much. Im really strugling with this subject so dont laugh ;-)

Answer 1

You're creating the object with a std::string, but your constructor is expecting a QString. As of Qt 4 (don't know if Qt 5 allows this), there's no implicit conversion from a std::string to QString.
Either pass a pointer to a null-terminated char array:
SavingsAccount accholder1(accName.c_str(), accNum);
or use directly a QString to read the account name.
EDIT: I've just noticed that your constructor expects 2 QStrings, yet you're passing an int as the second parameter. You can convert a number to a QString using the static function QString::number.

Answer 2

The problem is that somewhere you are creating an object without passing the correct parameters to the constructor.
For example if you have a class SomeClass with a constructor like this
SomaClass(Qstring s1)
you cannot create a SomeClass like this;
SomaClass t;
You have to create instead:
SomeClasst t("text");
