please help with: no matching function error

[NtobekoQt]

Please help with the following errors:

In constructor 'Savings::Savings(QString, QDate, double, double)':
error: no matching function for call to 'Assets::Assets(QString&, QDate&)'
note: candidates are: Assets::Assets(QString, QDate, QString, double)
note: Assets::Assets()
note: Assets::Assets(const Assets&)

You have no constructor for Assets that takes two QStrings.

You have to either add a constructor that takes only two QString arguments, add the two missing arguments to use the existing constructor, or give them default values in the header declaration such as:

Assets(QString des, QDate dat, QString t = "", double p = 0);

Assets(QString des, QDate dat, QString t = "", double p = 0);
