C/C++ :: Trying To Cout Vector

This is what my code looks like

class Transaction{
private:
char type;
double amount;
double balance;
string description;

[Code] .....

This part is what I am having trouble with as this section is not printing anything.

for (int i = 0; i < transactions.size(); i++){
cout << transactions[i].gettype() << " ";
cout << transactions[i].getamount() << " ";
cout << transactions[i].getbalance() << " ";
cout << transactions[i].getdescription() << " ";
}
}
