Deleting what i want in vectors

in a vector i put in what it is i want.

like cust id 1001 reg AAA

ect up to 1005 and EEE.

how do i make it delete 1003 CCC from the vector.

code i have is this.


void Manager::showHires()
{
string reg;

system("cls");
cout << endl << "List of Hires" << endl << "==============" << endl;

vector <Hired>::iterator iter = theHired.begin();
for(iter = theHired.begin();iter != theHired.end();++iter)
{
if(!isHired(reg))
{
(*iter).getDescription();
cout << endl;
}
}
}


void Manager::returnHire()
{
bool custfound = false;
bool carfound = false;
int id;
cout << "Enter Customer ID: ";
cin >> id;

if(findCustomer(id))
{
custfound = true;
}

string reg;
cout << "Enter CarRegno: ";
cin >> reg;

if(findVehicle(reg))
{
carfound = true;
}

if(custfound == false)
{
cout << "CustomerID not found!" << endl;
}

if(carfound == false)
{
cout << "Car RegNo not found!" << endl;
}
else
{
if(isHired(reg))
{
cout << "Car was hired and has now been set to AVAILABLE!" << endl;
setHired(reg,false);

Hired h(id,reg);
theHired.erase_element(h);
}
else
{
cout << "Car has already been returned!" << endl;
}
}
}
void Manager::createHire()
{
bool custfound = false;
bool carfound = false;
int id;
cout << "Enter Customer ID: ";
cin >> id;

if(findCustomer(id))
{
custfound = true;
}

string reg;
cout << "Enter CarRegno: ";
cin >> reg;

if(findVehicle(reg))
{
carfound = true;
}

if(custfound == false)
{
cout << "CustomerID not found!" << endl;
}

if(carfound == false)
{
cout << "Car RegNo not found!" << endl;
}
else
{
if(!isHired(reg))
{
cout << "Car is available and has been set to HIRED!" << endl;
setHired(reg,true);

Hired h(id,reg);
theHired.push_back(h);
}
else
{
cout << "Car is NOT available!" << endl;
}
}
}


trying to make it when i return the car it deletes what i put in and still shows the rest as they are still hired.

and help would be gratful

Don't know if this will apply to your problem, but there is a member function common to what you want to do. that is:


This code deletes the element at the position specified by the iterator.

everytime i try this bit of code i get an error.

the program adds hires in through the vector but it's not always the last or first hire that gets returned so i tryed

Hired h(id,reg);
theHired.erase(h);

hoping that after i have put the details in of the car im returning the erase might take it out,

anyone got other idea's???

Hired h(id,reg);
theHired.erase(theHired.find(h));

If you know its offset into the vector, do something like

theHired.erase(theHired.begin()+3); // erase the 3rd element

there is no such thing as a .find in a vector.

when i tryed it i got errors and when i looked up what goes with vectors it was not in it.

i tryed doing this instead

Hired h(id,reg);
theHired.erase(theHired.at(h));

but i get this error

error C2664: 'const Hired &std::vector<_Ty>::at(unsigned int) const' : cannot convert parameter 1 from 'Hired' to 'unsigned int'
1> with
1> [
1> _Ty=Hired
1> ]
1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Oops.
