For Loop Method Call - c++

Question

An error pops up saying the class type does not provide a subscript operator.
I'm new to c++ and can't seem to figure this one out. Would be really thankful if you provided me some tips and where I'm going wrong in my code outside of the problem.
class Transaction {
protected:
char * ime;
char smetka[16];
float iznos;
Date d;
public:
Transaction() {}
Transaction( char * ime , char * smetka ,float iznos ,Date d ) {
this->ime = new char[strlen(ime)+1];
strcpy(this->ime,ime);
strcpy(this->smetka,smetka);
this->iznos=iznos;
this->d=d;
}
Transaction(const Transaction & c) {
ime = new char[strlen(ime)+1];
strcpy(this->ime,c.ime);
strcpy(this->smetka,c.smetka);
this->iznos=c.iznos;
this->d=c.d;
}
friend ostream & operator<<(ostream & out, const Transaction & c) {
if(c.iznos>0) {
return out << "Inflow " << c.iznos << " " << c.ime << "(" << c.smetka << ")-" << c.d.getDay() << "." << c.d.getMonth() << "." << c.d.getYear() << endl;
} else {
return out << "Outflow " << c.iznos << " " << c.ime << "(" << c.smetka << ")-" << c.d.getDay() << "." << c.d.getMonth() << "." << c.d.getYear() << endl;
}
}
Transaction(char * ime, char * smetka) {
this->ime = new char[strlen(ime)+1];
strcpy(this->ime,ime);
strcpy(this->smetka,smetka);
}
};
class TransactionAccount {
private:
char * ime;
char smetka[16];
Transaction * t;
int n;
int kapacitet;
public:
TransactionAccount() {
this->t = new Transaction[3];
this->kapacitet=3;
}
TransactionAccount(char * ime,char * smetka) {
this->ime = new char[strlen(ime)+1];
strcpy(this->ime,ime);
strcpy(this->smetka,smetka);
}
void addTransaction(Transaction & a) {
if(n<kapacitet) {
this->t = &a;
} else {
kapacitet*=2;
this->t = &a;
}
}
Transaction getTransList() {
return *t;
}
int getTransCapacity() {
return this->kapacitet;
}
int getTransNumber() {
return this->n;
}
virtual ~TransactionAccount() {}
};
int main() {
char name[50],number[16];
float amount;
int d,m,y;
int n;
bool isInflow;
TransactionAccount ta;
int testcase;
cin>>testcase;
switch (testcase) {
case 1: {
cout<<"------Transaction test------"<<endl;
cin>>name;
cin>>number;
cin>>amount;
cin>>d>>m>>y;
Transaction t(name,number,amount,Date(d,m,y));
cout<<t;
}
break;
case 2: {
cout<<"------TransactionAccount test:constructor, desctuctor & get-
functions------"<<endl;
cin>>name;
cin>>number;
TransactionAccount ta(name,number);
cin>>n;
for (int j=0; j<n; j++) {
cin>>name>>number>>amount>>d>>m>>y;
Transaction t(name,number,amount,Date(d,m,y));
ta.addTransaction(t);
}
cout<<"Capacity: "<<ta.getTransCapacity()<<endl;
cout<<"Number of elements: "<<ta.getTransNumber()<<endl;
cout<<(ta.getTransList())[n]; // -- here is the
problem
cin>>n;
cout<<"The element on position "<<n<<" is "<<endl;
}
return 0;
}
My desired result is that it calls the previous object(of the class) and prints it.

Answer 1

The answer to this specific question is that getTransList returns a single Transaction (rather than, as the name would suggest, the 'list'). The error then happens because Transaction does not have an overloaded subscript operator (which is fine; it probably shouldn't).
Transaction getTransList() {
return *t;
}
should be replaced with
Transaction* getTransList() {
return t;
}
which properly returns the array.
However, there are many other problems with the code provided. Some will become apparent when you try to run/debug the code; for the rest, while you can of course ask (new) questions about specific problems on this site, you might be better served consulting your teacher.
